I Shall Be Happy (Attack On Titan Fan-fic) - Chapter 25

“C’MON! DON’T QUIT!! GIVE ME ANOTHER 10 LAP!”

Inside a room, where time is stopped, a boy was screaming at two girls. These girls were both trying their hardest to pull a heavy block of iron, weighing 500 tons, by using only their physical body. This training was meant to increase their physical strength, but not at the expense of making their muscle bigger. The point was to make their body as strong as possible by condensing their muscles to create greater explosive strength.

All of this training is for making their body sturdy enough to withstand the burden of the titan’s power while remaining human. If they somehow manage to attain 100% of their titan’s power, they will not only be as strong as titans, but each of their punch will create a more devastating impact. This is due to one of the laws of physics which stated, the smaller the surface area of something gets, the more concentrated power it can bring.

(A/N Mikasa’s power comes from the titan)

This is the reason why transforming into a titan is a very ineffective method of gaining strength. It made your body bigger, but at the same time, your strength is no longer as dense. So if you’re in a titan form and you’re punching something, a lot of that force disperse and become wasted. While if you’re in a human form and can exert the same force, it will pack a lot more power without losing much.

An analogy to this is like a sword and a stick. A sword can penetrate better (A/N ( ͡° ͜ʖ ͡°) ) while a stick will only push the thing forward.

As to why Athanatos is training both Annie and Mikasa when he actually despised Annie?

(MC’s POV)

“PLEASE MAKE ME STRONGER!!!”

Wtf? Why are you bowing and asking me this?

“Huh?”

“You’re the guy who drove away from the titans and unfreezes me right? You were that devil. I know you are strong. Probably the strongest in the world. I need your help to become stronger.”

“… you should have never told me that… I usually kill people who know my secret and you know there’s no reason for me to kill you.”

“You can’t do that! Mikan and Karl wouldn’t let you.”

“No… I can. I could just simply delete their memories about you.”

Then she was shocked. It seemed that she didn’t consider about this matter. Let see how she will handle this.

“Why do you want to become stronger, depending on your answer, I might just kill you.”

Then I use my power and look straight into her soul so that I can read her mind.

“I-I… I want to become strong enough to protect myself so I can be independent!”

[I… I want to be useful and not remain a burden. I don’t want to wait for the day the Marley to come invade us and take away my family… all because I was weak.]

Hearing her thoughts, I was stunned for a second.

I mean, she’s aloof most of the time and acting as if she was a cold person but deep inside, she sincerely cared about her family. She’s a bad liar, but her lies are just a cover for her not wanting to reveal her personality. Her communication skill is so bad that it seemed like she’s untalkative but instead she enjoyed having people she holds dear accompany her.

Damn… I’m now seeing her in a new light.

(A/N I’m using her personality from the anime and manga, with the addition of the AOT junior high. I highly recommend you watch this.)

Should I help her?

“You should be more honest with yourself. You’re a bad liar you know. I was just kidding earlier. I won’t kill you, you’re a part of us now.”

“Wh-a-at are you talking about? I’m, I’m telling the truth!”

“Come on, you’re stuttering. Tell me what you really want, then I will help you.”

“I-I-I… PLEASE MAKE ME STRONG ENOUGH TO PROTECT MY FAMILY! I DON’T WANT TO LOSE THEM!”

After a lot of hesitation, she finally spoke out her mind.

I can just deny her outright and she won’t be able to do anything. There’s also the option of wiping out her memories about the ‘devil me’.

But I won’t. I’m the type to believe that everyone should be given a chance to fight for their cause. Of course, that doesn’t mean I will help everyone, but Annie here is now a family member. Why should I deny her wish when all she wanted was to protect my family, our family.

“Ok… But be prepared for the worst, because the training won’t be easy.

“Thank you Athanatos-san!”

“Just call me Thana-kun, people who are close to me called me that. My name is quite long after all.”

“Ah… Ok…”

———————————

(Mikasa’s POV)

Thana-kun has been together with that freeloader for a while. She can be seen listening to Thana-kun’s instruction these days very obediently. Although she is still cold most of the time, she has been opened up more than ever before. It should have been a good change but what is this feeling in my heart.

Now, he even took her into the time chamber to train. When I asked her why he did it, he just replied, ‘She’s a part of us now.’

I don’t want to have less time with Thana-kun because of this.

“Mikasa! Don’t be distracted! Focus on condensing those muscles. You got 3 more ŀȧps! And you ANNIE, you’re too slow. Use the leg to propel forward while pulling it with all your upper body. Don’t waste a single muscle! Is your neck just for decoration? USE IT!!!

———————————

After finishing first, I collapsed to the ground while panting really hard.

“Mikasa… Are you alright?! Here, drink some water.”

Then Thana-kun approached me and checked the condition that I’m in.

“Phew… Your body is fine Mikasa, you just overworked it a little. Don’t always overexert yourself, keep it below the limit and only go over once you deemed necessary.”

Then he patted my head while also providing me some guidance.

“Thana-kun… We’re going to be together as always right?”

I asked him the same question again

“Hahahaha… Are you worried about that? Of course silly girl… We’re always going to be together. But don’t think about it too much. If I repeat it excessively, it will just lose its value as it makes it seems like you’re doubting me. We just need to prove it with action.”

“I’m not doubting you Thana-kun!”

“I know… I know…”

Then he bent his head down and gave me a kiss on the forehead.

“I don’t need any cheap talk… I just need both of us to have absolute trust in each other. And then time will tell the rest…”

(๑>ᴗ<๑) Blissful…

“OK!!”

(A/N If you’re doubting me about the weight that these girls can carry, then hear me out. The girls physical prowess came from the power of the titan. Mikasa has it because she’s an Ackermann while Annie is the Female Titan. The MC unlocked the power of the titan for these girls so they will have titan’s power even in their human form.

Then where did I get the weight from?

Ok… After analyzing the scene where Eren carried the boulder, I determined that the length of the boulder was about his height, which is 15 meters or a radius of 7.5. You put that into the equation V=4/3πr^3, which is the equation for the volume of a sphere. The volume of the boulder was 1767.15. After researching the density of what a normal rock should be, I got 1600kg/m^3.

You use the equation m= PV to get the mass. And voila, you get 2827.44 metric tons. The weight that these girls were carrying was 500 tons which is about 17% of the weight of the boulder. I think this is a good estimate. I may be wrong. )
