A Former Child Soldier Who Uses a Magic Sword Wants to Live with an Older Sister of a Former Enemy Executive - CH 47

And then, the day the Demon King’s army was expected to arrive had come.

That prediction came true, and the monsters had set up their camp away from the city.

Instead of being crowded as usual, the air in Ulaine Donagh was heavy with the soldiers’ tension and fighting spirit.

The request for reinforcements addressed to the royal capital was heeded.

They would come as soon as they were ready.

Our enemies are heavily wounded, but we can’t let our guard down with the presence of that magic sword soldier. If he alone unleashes that unrivaled power of his… the city will fall before the cavalry arrives. And the inhabitants will lose all hope. (Osiris)

Osiris glared at the Demon King’s army from the top of the city’s walls.

He was ready to launch himself at them.

Aware that it would be the biggest challenge he had ever faced.

Meanwhile, in the woods far from the city, a lone figure was moving.

『…Seto, can you hear me?』(Satis)

『Yeah, loud and clear.』(Seto)

Seto was moving carefully through the woods.

He had been hiding there since yesterday, waiting for the arrival of the Demon King’s army.

As they closed in on the city, the boy moved closer to their position.

『In order to strike at the Demon King’s army from behind, you will have to go a little further through the woods to a hill with several rocks on it. They are positioned just beyond that point.』(Satis)

Satis was communicating with Seto from afar using a telepathy spell.

『From there, I’ll have to remain concealed and crawl along so as not to let them spot me, right? I’m used to that kinda stuff.』(Seto)

『Be sure not to let your guard down just because you’re used to it. Now, I wish you luck. I’ll call you back later.』(Satis)

Satis cut off the telepathy.

Using it as a means of communication was a smart move.

Even from afar, she could give precise instructions to the boy.

However, if there was one downside to this method, it would be that Seto could not use it to talk to Satis unless she contacted him first.

Although he possessed the unique ability to wield a magic sword, he did not have one speck of talent when it came to sorcery.

Therefore, he could not use sorcery, much less a telepathy spell.

Well, I’m not one to look a gift horse in the mouth. …And I gotta make it back alive no matter what. (Seto)

Seto remembered the seashell accessory Satis made for him at the beach.

He did not forget the deep emotion he felt when she gave him his first gift.

In order to avoid losing it or breaking it during this mission, he asked Satis to hold on to it for him.

He would come back alive and see her again without fail.

Then he would put on that accessory again.

I’m almost out of the woods. …Next I gotta locate the enemy camp. (Seto)

Crouching in the shadows of the grass and between the trees, he glared at the flank of the Demon King’s army.

Starting now, he would get behind them undetected, and take out the Lizardman leading their regiment.

He spent a while checking the enemy’s position, then the monsters began to form up to go to the front lines.

At that moment, a telepathic message from Satis went into his brain.

『It looks like the battle is about to begin.』(Satis)

『Yeah, there’s barely any monsters left in the camp. …Actually, there aren’t so many monsters going to the front lines either. And they’re all wounded.』(Seto)

『I can’t believe they’re sent to the battlefield even though they look so worn out… I have no idea what in the world is going on in the Demon King’s head. But it doesn’t matter. Now is your chance. Please keep going. …Stealthily.』(Satis)

『Yeah, I know. …────From now, I will launch my surprise attack.』(Seto)

Seto lowered his center of gravity by adopting a crouching stance, and moved on while occasionally hiding in the shade of the grass and the rocks.

He could see a few monsters guarding the perimeter of the camp here and there.

He proceeded cautiously so as not to be spotted by them.

Normally, he would have preferred acting at night, but considering the danger posed by the magic sword soldier Sebek, the boy decided to challenge him to a brief but decisive battle.

With this grass camouflage cloth Satis made for me… and this telescope… (Seto)

Since he was close to the enemy camp, he had to lay on the ground completely.

He covered himself with the cloth, and looked for a gap in their defense.

At the same time, he heard the monsters shout from even farther ahead.

Apparently, they had launched an assault to bring down the city.

Okay… Found the hole in their security. (Seto)

Seto mobilized all the covert action skills he had built up over the years to sneak behind enemy lines.

Now let’s go back to the battlefield.

Legions of soldiers and adventurers, gathered together to defend the city, clashed with the monsters.

Men, women, and monsters killed and were killed by their opponents.

However, the humans still had the advantage.

One of the reasons for this was Osiris’ hard struggle.

Thanks to his magic gear allowing him to fly, and the light slashes of his magic sword Athribis mowing down his enemies.

[There is no escaping this magic sword of mine…!!] (Osiris)

The monsters fell one after another due to his aerial attacks.

However, the Demon King’s army also brought monsters capable of flight to this battlefield.

Osiris’ aim was accurate, and he shot them down one by one. However, the ones that remained flew around him at high speed, breathing out fire and the likes at him, and gradually driving him into a corner.

[Hmph! Not bad… But if you think you can finish me off with that, you’re sorely mistaken…!!] (Osiris)

As soon as a green glow emanated from his eyes behind his visor, he manifested a second magic sword out of thin air.

[The King’s Heart Athribis is a two-in-one magic sword! This is its true form!] (Osiris)

With that, he spun both of his magic swords with his fingertips in a fast and graceful motion.

Then, he firmly gripped the handles, and fired in bursts at the flying monsters.

[GUGYAAAAHH!!?] (Flying monsters)

Their bodies were gouged out and they fell to the ground one after another.

Without losing that same momentum, he directed his shots at the monsters on the ground, shooting them down one by one.

[Wooow… So this is the power of the magic swordsman of Ulaine Donagh. How terrifying…!] (Goburoku)

While Goburoku was trembling in fear, Sebek, who was mercilessly swinging his magic sword at the humans, turned his attention to Osiris.

[An attack from above? Well, isn’t that interesting.] (Sebek)

[This is no time to be so carefree! Can’t you do something about him!?] (Goburoku)

[Fine, fine. I just gotta kill him, right? But before I do… Are you still hesitating? We’re on a battlefield, remember? You could die, you know? ] (Sebek)

[…My blade wasn’t made to cut down women and children.] (Goburoku)

[And I’m telling you, quit using the back of your blade and letting them go. You’re a monster, aren’t ya? They’re your enemies, so kill them. We’re not playing swordfight in a playground.] (Sebek)

[I’m a goblin second, and a warrior first. Even if this is a battlefield, staining my sword with the blood of women and children is a disgrace…!] (Goburoku)

[You just don’t get it. When you go out on the battlefield, whether they’re a man or a woman, it doesn’t… MATTER!] (Sebek)

Saying that, he dodged the blade of a swordswoman who was trying to slash him from behind, and stabbed her.

Goburoku grimaced for a moment when he saw this, but the humans who immediately rushed over pointed their blades at him, and he readied his sword once again.

[…Amateur.] (Sebek)

[Am I… being crazy?] (Goburoku)

[How should I know? …Hm?] (Sebek)

Right after he thought about dealing with Osiris, he suddenly took a glance at their own military camp.

He instantly realized that the situation inside it had gotten a little suspicious, and smirked.

[Goburoku, you stay here and fight!] (Sebek)

[W-What!? H-Hey!] (Goburoku)

Goburoku’s complaints fell on deaf ears, and Sebek ran back to their base with a gleeful smile.

His leg strength as a human-demon hybrid was so great that he was back in the camp in no time.

It was there that he saw the object of his great delight, something both incredible and that he himself wished for.

[I found it… My wonderful encounter!] (Sebek)

What he found there was Seto, a boy wielding his magic sword to exterminate the monsters within campgrounds.
