Shinmai Maou no Keiyakusha - Book 2: Chapter 0: Prologue: Peerless Devil Lord Sister in the Morning

Every man has imagined it at least once.

About how a cute girl snuck into your bed before you woke up.

A warm and soft sensation. A faint sweet fragrance.

The girl saying a little bit embarrassed, but with a smile— Morning.

That was a happiness only granted to a limited amount of people.

“…………..”

However, on this morning, Toujou Basara, suddenly waking up from a feeling of suffocation, was put into a situation close to it. It wasn’t like he had a nightmare. The feeling of suffocation originated from something else.

The origin was— a little girl under the blanket in Basara’s bed. The little girl had crawled up below the blanket, right into the T-shirt Basara was wearing.

Moreover, the little girl’s adorable face was right in front of Basara’s eyes. In other words, the little girl’s head shot out of the collar, where Basara’s head was already coming out.

“Good morning, Basara-san.”

“Maria…? Eh, wait a sec— Uwah!?”

Since they were stuck together face-to-face, not even the slightest movement was possible.

—No, physically it wasn’t impossible. The wide T-shirt Basara wore instead of a pyjama shirt was made of a good, flexible material. But— even though it was made like that, would it endure this excess?

“Oh no~ You cannot do that, silly Basara-san. It is quite dangerous to force yourself to get up.”

He got pissed off at that reaction, but couldn’t give a retort. Instead, Basara stiffened up.

Because Basara felt a soft and smooth sensation over the broad area of his chest to his stomach under the T-shirt, under which Maria had slipped into. Without a doubt, it was from Maria’s bare skin. In other words,

“A- Are you… naked under my T-shirt—”

“Oh please, Basara-san. There is no way I would be so rude as to enter someone else’s bed with my clothes still on.”

“Screw your unnecessary consideration!”

If so, be considerate about the ultimate rudeness of entering someone else’s T-Shirt.

“—Actually, why didn’t I wake up before this all happened?”

It was a slight shock for him. Upon that,

“Have you forgotten, Basara-san? I am a succubus. A devil that appears in dreams. Sleeping spells are my specialty.” Maria laughed with a fufufu.

“Of course it might not have worked if you were awake, Basara-san. However, it was a sure thing while you were asleep, defenseless. You let your guard down.”

“That’s a damn premeditated crime!”

So much for the police when he couldn’t even sleep calmly in his own room.

“Oh please, Basara-san. Even though you are really happy about it. Come on, be honest.”

Showing a roguish smile, Maria entwined her arms around his neck, brought her body even closer and glided her skin by pressing onto him.

…Wait, this is bad…

Even with young features and a small body, Maria was still a proper girl. Her looks were proud of an extraordinary cuteness and honestly, this distance was dangerous. The smooth skin unique to girls, the moderate yet soft swellings of her breasts, all of Maria was only a stimulation to Basara, a boy. Above all, there were two tickling sensations on Basara’s body matching with Maria’s movements. They were most likely Maria’s nipples, whose sensation became more firm with every rub.

“Mm… Ah… Mm… Fuh…”

Her childish expression turned gradually sexy and the voice she leaked started to fill with passion.

“I, I get it. …I admit defeat. Please, just get out of my T-Shirt.”

“I refuse.”

“S- Say what?”

On his panic, Maria changed her satisfied smile into a roguish one.

“The inside of your clothes already belongs to me, Basara-san. If you insist that I leave, you need to tell me ‘Maria… I want to come inside you’— Yes, quietly moaning with a sweet voice!”

After responding to the overly cheeky succubus girl with silence for a while,

“Maria…”

“Basara-san.”

Maria unnecessarily sparkled her eyes, whereas Toujo Basara dropped his right fist onto her head.

A dull ‘BAM’ sound. Maria leaked an “Ouh” voice of anguish, then turned teary.

“Y- You raised your hand against a girl!”

“Yeah… I’m a horrible guy. But you’re even more horrible, so I had no other choice!”

Basara swiftly pulled back both his hands through the sleeves, then pushed away Maria’s body inside the T-Shirt to a secure space.

Then he kept his eyes shut so as not to see her naked and immediately retreated out of the T-Shirt.

Basara, naked on top, said to Maria, who wore his T-Shirt like a one-piece dress.

“Actually, what’s with ‘quietly moaning with a sweet voice’? …Well, though I somehow already know.”

“The Japanese language is quite difficult. But I believe the important part in communication is to convey your feelings. The MIND.”

“No. The important part in communication is etiquette and common sense.”

First of all, never enter my T-Shirt without my consent. I’ll sue you for illegal trespassing.

“Jeez, what a morning…”

Basara left his room wearily. He couldn’t let Maria be naked, so he gave up on getting his T-Shirt back for now and went down the stairs dressed in shorts and topless.

The end of summer with no sight of fall coming. The temperature was still high, so he didn’t feel cold.

To awaken his half-asleep head, Basara headed to the washroom.

While scratching the back of his head, he opened the wood patterned door and went inside.

“———”

Inadvertently he stood still. Because there stood the other girl that was living together with Basara— Naruse Mio.

—Basara came to the washroom to wash his face and brush his teeth, but the place had another function.

It was the changing room for those that entered the bath in the back. Therefore,

“…….”

Basara was captivated by Mio and her appearance.

A single bath towel— That was how Mio right in front of him looked like right now.

She was beautiful. He didn’t know if she took a morning bath or shower. Nevertheless, her flushed face, but also her body still covered with water drops and her shiny wet hair that reached till her waist; all of it was beautiful.

Moreover, her proportions were already closer to an irregularity than unsurpassable. Her overly tempting big breasts and curves that ran from her slender waist over her bottom down to her thighs, drew a charming body line that wasn’t typical for the Japanese. Her body was clad in a white bath towel, which boosted her sex-appeal, and perfectly emphasized that Mio was a girl. Basara inadvertently stood stock still from the stimulation that was too strong right after getting up, whereupon

“—–”

He saw Mio’s face getting red, taking a breath. She’s gonna scream— The moment he thought so, Basara reflexively moved. He opened the door of the washroom/changing room behind him, rushed out at once and considered how to apologize.

…However.

To avoid such incidents, they supposedly made various arrangements as a countermeasure when they started to live together. Even so, the sign with “Girl’s time” hadn’t been hung on the door. Did she forget to hang it? No, Mio wouldn’t make such a careless mistake. Then,

…Must’ve been Maria…

Most likely, before Maria came to Basara’s room, she passed by the bathroom and removed the sign that Mio had put up. Nothing unusual for the prankster Maria. How troublesome.

That said, he knew what to do. He didn’t know if Mio would believe his excuse, but he could only properly explain the circumstances to her and beg for her forgiveness. So Basara nodded with “Okay”— and suddenly realized. Before he had noticed, Mio stood right before him.

He had thought for sure that she would be filled with rage, but Mio didn’t say anything.

“? Huh…?”

There Basara realized another thing. His left hand was around Mio’s waist while his right covered her mouth. And— for some reason, Basara was inside the bathroom instead of outside.

“…Ehm, just what’s going on…?”

While saying so, his intonation at the end of his sentence was trembling. He broke out in a cold sweat.

Mh, how weird. By chance, could it actually be?

In other words, it was that. His mind, faced with an extreme situation, escaped reality and made him imagine leaving the bathroom. Something like an alternative future kaleidoscope? In reality, he had forcefully pulled Mio, who was going to raise a scream, closer and covered her mouth against her will!?

“——-”

Oh my god. He wanted to prevent her from screaming due to a misunderstanding that bad? Apparently his body had outdone his mind. That said, the situation had only taken a turn for the worse, getting to the worst case. As Mio’s bath towel had fallen down in the moment he forcefully pulled her closer and shut her up by covering her mouth, their bodies were in direct contact now.

“…….”

She must have been perplexed by the all too sudden situation. As she didn’t know how to react, Mio – dumbfounded – stayed in Basara’s arm without moving.

Anyhow, right now Mio was completely naked. Since Basara lent Maria the shirt he was wearing, his top half was naked. What happened when they hugged in that state was clearer than crystal clear.

Even while he knew he shouldn’t, Basara dropped his gaze, where Mio’s overly voluminous breasts stuck to his stomach region and to prove their first-rate softness, they were squeezed into a lewd shape. Different from Maria’s, their size and sensation were both visually and sensually destructive to the max.

“S- Sorry, this— Uwah!?”

Basara tried to hastily jump back and grandly slipped on the water that had dropped from Mio’s body and hair. Naturally the embraced Mio was dragged into it too.

“—Kyaa”

Basara instantly reacted to the scream from within his arms. While forcefully twisting his body in mid-air, he pulled Mio closer and somehow managed to bring his body under hers before they hit the ground. Turning himself into a cushion, the impact Mio received from the fall was reduced. Since he was holding Mio, both his hands were occupied, but he barely managed to absorb the fall with his back, arms, and shoulders.

Even so, the impact from the fall gave him a dull pain and he tried to get up while scowling.

Like that, he plunged his head into some soft things.

“—Hyahn!?”

“? S- Sorry!”

On her surprised voice, Basara noticed his next mistake. He most likely had buried his face into Mio’s breasts. He hastily grabbed Mio’s shoulders and tried to get away.

“Hey, Yah… Not, there…”

But Mio raised a sweet voice in bewilderment, leaving Basara surprised about the sudden occurrence.

Not only because of Mio’s voice, but also because the shoulder he supposedly grabbed was surprisingly soft.

—Of course a girl’s body was softer than a boy’s, with no exception at the shoulders.

However, this sensation was clearly from something different than a shoulder. And then Toujou Basara finally realized the situation he was in.

“Eh…m.”

Mio’s face, who he had thought was right before him, wasn’t there. There was only a crack. Her bottom.

However it happened, Mio was on top of Basara the other way around of him.

Basara hadn’t plunged his head into Mio’s breasts, but her groin area. And what he grabbed, believing it to be her shoulders, was her bottom. On top of having ended up tightly holding the curving portion on both sides that led to her thighs, he ended up spreading that crack by pushing up what he believed to be her shoulders. Basara unexpectedly got a look at Mio’s everything.

“—KYAAAAAAAAAA”

This time Mio hastily jumped away from Basara along with a scream. Grabbing the bath towel on the ground with her face red, she pulled it up to herself to hide her body.

“Why’re you coming in when I’m already inside!? Pervert! I’ll kill you a hundred times!”

Even though there was a more important matter, Mio shouted the original problem as she got upset.

“Sorry! The door didn’t have the sign, so I thought—”

“Liar! Come up with a better lie for an excuse, Basara!”

“No, it’s not a lie! Really, believe me!”

Basara opened the bathroom door by pulling it to himself while shaking his head from side to side.

“See, no sign. Right?”

“No way… I certainly put it on.”

Mio, seeing that there was no sign, couldn’t believe it.

“Don’t tell me, you hid it… Did you want to peek on me bathing and if you were to get caught, you wanted to blame me for forgetting the sign while saying ‘It’s an accident’?”

“As if! Besides— if I did a cowardly act like that, everything would be over!”

Living together with Mio and Maria started with the talk about Jin’s remarriage. In the end, the remarriage was just made-up, but even so, Basara considered Mio and Maria as his little sisters— as his new family. That didn’t even change after he found out that Mio was actually the daughter of the previous Devil Lord Wilbert and that Maria is her succubus attendant. The reason was that the same applied to Basara and Jin as well. However, their relationship was far from normal and to live together under the same roof, trust was needed more than anything.

—Just the other day, Basara drove away the enemy that came after Mio and succeeded in saving Mio from her inherited power that had gone out of control. One way or another he managed to help the girl he wanted and swore to protect. Before, there had been some anxiety in their mutual trust, but Basara believed that thanks to that incident they would be able to get through together now. As proof,

“… I see. Yeah, right…”

Mio, calming down a bit, accepted Basara’s words. If he had done any dirty act that betrayed Mio, the finally established trust would be ruined.

Basara wouldn’t do something so stupid— She must have believed so.

“But… then why?”

“I didn’t remove the sign you put up. That only leaves one suspect, right?”

To be honest, Basara didn’t want to suspect the other person living with him. He didn’t want to, but she slipped into his T-Shirt early in the morning after all. He might have taken her side if that hadn’t happened, but now he could no longer cover for her.

“Mhm~ I see… That’s how it is. Then I’ll have a looong talk with her later.”

Mio said while showing an intense smile, but suddenly,

“But— You should be able to know my whereabouts with the Master-Servant magic. Why did you come inside?”

“Hey… Have you forgotten about it in your rage?”

Basara sighed on her question. Certainly, Basara and Mio had formed a “certain contract” with magic and if they wanted, they could locate each other. But,

“We agreed to not search for each other with it unless it’s an emergency, since it’s an invasion of privacy.”

At worst, they could find out various things like when one was taking a bath, when one was on the toilet and for how long they did that. Even if they were a family living under the same roof, it honestly wasn’t wise to know that much about the other.

Above all, they were teens.

A minimal amount of privacy and consideration called for the appropriate indifference needed for a boy and a girl living together. It was a pact made out of necessity for them and they agreed to not search for each other habitually.

“You’re right, sorry… But Basara, why did you suddenly cover my mouth then instead of getting out when you noticed I was inside earlier? And you were quite forceful at it.”

…Right. Of course she would be bothered about that.

“Moreover— Why aren’t you wearing anything on top today of all days?”

When asked further with an upturned gaze, Basara was at a loss for an answer.

Forcefully covering Mio’s mouth was a reflexively unconscious action.

To explain the matter about him being topless would also require telling her about the incident with Maria.

But he got the feeling that explaining either of these would only sound like an excuse.

“Ehm…. I’m sorry.”

Basara lowered his head. He himself was partly responsible for making Mio feel embarrassed.

“I see— But it’s fine, you don’t need to apologize, Basara.”

On this calm voice, Basara made a sigh of relief while raising his head— and then he saw.

Mio, clad in the bath towel again, grinning while emitting a pale glint from her body.

“—I’ll forgive you with fifty thousand volts.”

The moment she said so, the small lightning she released turned into a high-voltage stream and ran through Basara’s whole body.

“Aw, damn… What a disaster.”

After Mio gave him that lightning attack and left the bathroom, Basara got into the bath and took a shower. He wanted to wash his body that had carelessly dropped on the floor topless, and while it was the end of summer, the heat was still enough to make him sweat during sleep. Because of that, Mio must have taken a shower like Basara now too.

—There was a reason to why Toujou Basara could accept a situation like that.

It wasn’t only because he ran into Mio in the bath numerous times or had bold morning happenings with the other gender due to Maria. Maria was, like she proclaimed herself, a succubus, meaning a devil that appeared in dreams, whereas Mio was raised as a human, but could use powerful magic as she was the child of the late previous Devil Lord. Naturally it would be rather difficult for a normal human to live together with these two.

Even so— Toujou Basara could stay and live together with Mio and Maria, because he had a tolerance for principles that escaped the common world.

That tolerance was related to Basara’s birth and past.

“………….”

Suddenly recalling his past, Basara got a gloomy expression. Even so,

“I have to keep it together…”

Basara’s reliable father— Toujou Jin was currently out of house due to certain reasons.

Put in charge, he had to protect his sisters, Mio and Maria, by himself as the oldest son.

“Fuh…”

While washing away the sweat, the shower gradually warmed up Basara’s body. It was a human instinct to wash one’s head too when getting it wet.

“Argh…”

His body was still a bit numb from Mio’s lightning attack, so he couldn’t properly wash his head.

“—Leave it to me.”

Along with a calm voice, slender fingers entered Basara’s hair and started to gently wash his head and hair.

Just like at a barber, it felt pleasant to have someone else wash your head.

“Oh, thanks. How thoughtful…. Eh?”

Basara noticed the abnormal situation too late since it was conducted all so naturally, and finally turned around. There was a girl clad in a bath towel making a puzzled face.

Finely chiselled features. Looks that could pass her off as a model because of her tall and slender figure.

A clear beautiful girl of a different type from Mio and Maria.

“Y- Yuki… wh- why are you here…?”

Basara was inadvertently surprised and confused. Right in front of his eyes was his childhood friend Nonaka Yuki.

—A few days ago, Basara had reunited with Yuki after five years. Yuki had become so beautiful that she appeared to be a different person. Basara had only known her young appearance, so he was honestly surprised at her change and growth.

That said, they only met each other again and certainly didn’t live together. In fact Yuki shouldn’t be in the Toujou House— let alone the bath in the morning. She made her usual expressionless face.

“I came to pick you up. I wanted to go to school together with you.”

“I- Is that so… No wait, how did you get into the house?”

Regrettably, there was quite some bad blood between Yuki and Mio/Maria.

It resulted from their standpoints and partly due to their emotions.

“Through the door. The succubus let me in.”

That damn loli succubus. She wasn’t satisfied by just slipping into my t-shirt, she also had to play yet another ridiculous prank!

“But, when did you get into the bath…?”

“I didn’t want to disturb you so early in the morning. —So I completely erased my presence.”

“Your modesty is getting out of hand!”

A guy with a weak heart would die, when someone suddenly washed his head from behind!

Yuki uncaringly brought her body closer.

“Basara… can I wash you?”

“N- No, it’s not good to be in here together, Yuki… You know that, right?”

“…Why? We often did so in the past.”

“No, that was five years ago— when we were kids!”

They both were no longer innocent kids. Even through the bath towel, he could tell. Yuki’s body strongly emphasized that she was already a fine woman.

Basara hastily wrapped a towel around his waist.

“Besides, you can try to play calm, but your face is red, Yuki… You’re embarrassed, right?”

“……..Yeah. A bit. But I wanted to take a bath with you.”

One breath.

“Do you… hate taking one with me, Basara?”

“No, I wouldn’t say that I hate it…”

Being looked at from below at a very close distance, Basara inadvertently averted his eyes out of shame. He was hesitant to say “I would love to”, so he equivocated, but she seemed to understand that as a refusal.

“Huh… Ehm, Yuki-san?”

“………”

Yuki had gotten a somewhat displeased expression. And,

“…You took one with Naruse Mio and that succubus, yet you ain’t takin’ one with me?”

Her speech showed a bit of her dialect. It was a habit that occurred when she couldn’t suppress her emotions.

The stuff Maria revealed the other day on the rooftop must still affect her— But, it was already too late by the time he analyzed that.

“H- Hey…!?”

Not listening to Basara’s attempt to stop her, Yuki undid the knot of her own bath towel.

The white cloth fell onto the ground and Yuki’s smooth and beautiful skin was exposed.

He hastily turned around, but even so he had gotten a good look.

On how much Nonaka Yuki had grown and how beautiful her body had gotten. Moreover,

“—Basara, let me wash you.”

Saying so in a more demanding tone than before, Yuki pressed her body firmly onto Basara’s back by hugging onto him. Yuki put her cheek against Basara’s back, which had gotten all stiff from the earlier destructive sensation.

“If you don’t let me wash you— I’ll do something even bolder.”

Her calm voice was filled with seriousness, so Basara resigned right away.

“F- Fine… Wash me. So spare me of anything more…!”

He was neither a hermit nor a saint. He was a healthy young boy. It was bad enough already, so if she were to do anything more, his reasoning would completely break.

As she regained a bit of her spirits by getting his approval, Yuki changed her tone back into a calm one with “Then don’t move” and started to wash Basara’s head. Her gentle and careful handiwork made him feel Yuki’s serious personality and above all, her precious feelings towards him.

…Five years, huh.

Compared to the time when they were young and innocently washed each other’s body, both Basara and Yuki had changed in various ways now. Not just their age, but also their standpoints and relationships.

—However, there was still something that hadn’t changed.

How Yuki felt preciously about Basara.

Likewise, the way Toujou Basara felt about Yuki as someone important was unaltered.

“…..”

“…..”

At some point both of them had fallen silent.

But it wasn’t awkward. It was just a silence brought about from their feelings.

Before long, the water from the shower washed Basara’s head clean. Then,

“….Basara.”

Suddenly. Yuki called out to him from behind. In a really quiet voice.

“You and Jin-san won’t ever come back to the …?”

Basara replied with silence to the asked question. That was the very reason why Basara could accept Mio, a descendant from the Devil Lord, and Maria, a succubus.

—The Yuki mentioned wasn’t referring to a simple village in the countryside.

Earlier Yuki had said that the succubus had let her into the house.

That was a statement from someone that admitted the existence of devils like Maria. To protect this world from devils, the kept fighting since ancient times— That was Nonaka Yuki’s true identity.

And Toujo Basara as well, had once fought for the same mission.

Yes— Until five years ago, when the cruel tragedy befell the .

A lot of villagers were massacred by a young man that was possessed by a sealed S rank evil spirit.

At that time, Basara saw a lot of comrades getting killed before his eyes and even his friends were in danger, so his own power went out of control. His skill that actually was supposed to erase only an enemy’s attack, banished everything, like the possessed young man and the limbs of his killed comrades, into the zero-dimensional space. Afterwards the decided to confine Basara to a prison, but Jin, Basara’s father, objected. As a result, Basara and Jin were stripped of their Hero title and had to leave the village. In other words, they were chased out. Therefore,

“…I think that’ll prove to be difficult.”

Of course he had a nostalgia towards the . But the scars the tragedy caused five years ago still remained unchanged. Be it in the village, in the villagers— and even in Basara himself.

Even now, five years later, Basara kept having nightmares of that day.

—Besides. Toujou Basara had already set out on a new path.

To protect the girl, who unwillingly inherited the power of the previous Devil Lord and was chased for it by the current Devil Lord and his subordinates— Naruse Mio. Neither the Devil Lord, Mio’s standpoint as a devil or his past as a Hero mattered. He swore to protect the two as a family, as their brother.

But that was something adverse to the Hero Tribe’s doctrine. That Yuki helped out in the battle the other day was an exception of exceptions. They both understood that.

“But Basara—”

It was in the moment when Yuki tried to say something with a somewhat pleading tone.

Outside the bath— The door that separated the anteroom of the bath from the hallway, opened after a knock.

“Could it be… you’re still inside, Basara? Breakfast’s been done for a while now, you know.”

Basara froze up on Mio’s voice from the anteroom.

She must have come to get Basara, since he just wouldn’t finish his shower. Even though that incident happened just a few minutes ago— Mio was basically very caring. When they moved into this new house to live together, she also tagged along with him when he asked her to show him around, albeit stating her complaints. The education of her late foster parents that raised her in the human world must have been good. They seemingly were subordinates of Mio’s real father, the previous Devil Lord, but they must have been good people without a doubt.

—However, now wasn’t the time to reminisce about Mio’s past.

After all Basara was currently together with the naked Yuki in the bath.

“S- Sorry… I’m coming now. Yeah, I’ll be able to get out in a bit…”

While replying hastily, Basara handed Yuki the bath towel that was laying on the floor. When he urged her, “Please wear it!”, with his eyes, Yuki started to wrap up herself with the bath towel while showing an annoyed face.

“…Hey Basara, are you angry about earlier?”

There came a question from Mio with a little worried tone. She must have thought that the lightning attack was overdoing it.

“B- But you were at fault, you hear… I mean, I just got out of the bath, but you suddenly came in and hugged me. You were so rough, so the bath towel became undone and even did that during the commotion… I was really embarrassed.”

“S- Sorry… But that was…!”

Basara raised a scream in his heart. What Mio mentioned was certainly the truth. It was the truth, but from that selective utterance, one who didn’t know the circumstances would probably misunderstand. And as expected,

“——–”

Yuki narrowed her eyes and opened the fogged window of the bath for some reason. And then,

“(H- Hey, what’re you doing…Yuki?!)”

In front of Basara, who asked with a small voice, Yuki unwrapped her own bath towel of all things and threw it out of the window. GYAA, from the shock, Basara became like the painting “The Scream” from Munch.

“? What’s up, Basara?”

“N- Nothing. It’s nothing.”

He desperately tried to smooth it over, but Yuki closed the window and approached Basara.

As he couldn’t escape because of Mio, she clung to him from the front.

“Basara… what did you do in the commotion?”

“(W- Well, just a little accident… Really!)”

Basara declared, trying to pacify Yuki who asked him by looking up to him. Whereupon outside the bath,

“Well… if you say so.” Mio said.

“But Basara— Why is there a female school uniform and underwear, which don’t belong to me here? And they’re folded so neatly.”

Sorry, these are mine. I’m actually a cross-dresser, ahahaha— That’s not gonna work, damnit!

Excuses were impossible. Basara resigned and at the same time, the door of the bath opened mercilessly.

“………….”

Awkward to the max. After a silence from all three, Mio opened her mouth first.

“…What has water on top and a big fire below?”

“A, A bath, right…?”

While being clung onto by the naked Yuki at the same time, Basara answered with “Haha”.

“—Certainly. Well then, what has fire everywhere, top and below?”

Mio’s dangerous eyes were saying: Trick question, go.

“W- Well~ I wonder what. Maybe a burnt out SNS?”

“No, wrong— You see, it’s you, who’ll be covered in flames now!”

The emotion she held back exploded. She was about to release her magic like her rising anger— In that moment, Mio suddenly shivered her body with an “Ah”. And then,

“Yah… No way, now…? —Ahhn.”

While suddenly letting out a sweet voice, Mio slumped and sunk down on the floor.

“H- Hey— Are you okay?”

When he hastily rushed over, there was a collar-like mark around Mio’s neck.

“Uwah… The curse of the Master and Servant contract!”

“…What’s the matter?”

Yuki was puzzled by Mio’s strange behaviour, whereas Basara looked at Mio, who emitted a sweet allure, while giving her the bath towel that he had prepared for himself.

…It hadn’t activated for a while now.

Actually— Basara and Mio were currently bound by a magic “Master and Servant Contract”.

Maria suggested it, since the contracting parties could locate each other, so when Mio was in danger, Basara could find her.

Originally Mio was supposed to be the Master, but for some reason the contract was formed reversed. Basara had become Mio’s Master.

Moreover, this contract aimed at solidifying the relationship between Master and Servant, so when the servant betrayed or had a guilty consciousness towards the master, the curse immediately activated.

Their contract was chanted with the help of Maria’s power, so the activating curse got the special characteristic of Maria the succubus.

—Dream Devil, Incubus, Succubus. Its special characteristic was “aphrodisiac”.

During the incident where Basara had entered the anteroom with Mio in it, she chanted the lightning attack after Basara’s apology, so there was no problem. But this time Mio was worried if she maybe overdid it earlier. So when she tried to attack Basara now, she must have felt guilty somewhere in the back of her heart. That might have switched on the curse.

“Yah, Ah… Hahn, Fuh… Mm…”

She desperately bit down on her lips to stifle her voice, but she couldn’t suppress the stream of pleasure that beset her whole body.

Mio twisted her body on the floor unbearably, whereupon the door of the anteroom was opened with attitude.

“Excuse me! Did I make it right here for Mio-sama getting all submissive in pleasure?!”

Howsoever she noticed, Maria came in quickly.

And when she saw Mio on the floor and the naked Basara and Yuki, she sparkled her eyes with “Ohh”.

“I thought this would happen, so I bought this in advance. The world’s smallest and lightest! The never fading memories, the memorials of youth will be with you!”

Swiftly setting up a small video camera that she pulled out from wheresoever, Maria started to film Mio.

“…………”

Basara wordlessly grabbed her at the nape of her neck, threw her into the bath, shut the door and mercilessly blocked it from his side with a mop and the washing machine. BAM BAM, the sound of the door being hit came from the other side right away.

“What are you doing, Basara-san! Are you still angry about the t-shirt? I apologize for hiding Mio-sama’s bathing sign! I can stay here, but at least the camera… Please use the camera at least! For my pride and soul as a succubus, I have to film the current Mio-sama!”

“Shut up! Restrain yourself, damn loli succubus!”

Basara succeeded in isolating the root of all this, squatted down beside Mio and softly lifted her up.

“—Are you okay, Mio?”

“It’s your fault… Mm, St- Stupid Brother… I’ll kill you a hundred times.”

Mio, full of pleasure, entwined her arms around Basara’s neck and tightly clung to him, albeit vexing. Calling Basara “Brother” was Mio’s unconscious habit that appeared when the curse of the Master and Servant Contract activated.

But most likely the activated curse wasn’t that strong. If she were to lay down and rest, the curse should ease up soon. Nevertheless Mio had an unyielding spirit. She surely didn’t want Yuki to see her like this. The only way to cancel the curse in no time was for Basara to subjugate the servant— Mio, as her master, and confirm her loyalty.

The things he could do were inevitably limited in this state, where she drowned in pleasure. Therefore,

“Okay… Let’s go to your room.”

It certainly would be embarrassing to use the sofa in the living room so early in the morning.

“Sorry, Yuki… She’s feeling a bit bad, so I have to tend to her. I’ll be right back, so wait in the living room after you put on your clothes.”

“…………Okay.”

As she understood that Mio’s state was strange, Yuki nodded, albeit a bit displeased. So Basara left the anteroom while carrying Mio.

Walking down the hallway, he thought while going up the stairs to the second floor.

He wanted to protect Mio’s everyday life, but he got the feeling that it didn’t include this situation.

At this rate Basara’s reasoning, endurance, soul and body definitely wouldn’t last.

At some point he would certainly commit a mistake. He couldn’t afford to hurt Mio— his little sister in that horrible way.

Therefore Toujou Basara mumbled quietly. It was a shame to abandon the merit of being able to locate each other, but

“On the next full moon, where we can annul the contract, I’ll break this Master and Servant Contract— My body can’t take it.”
