Ability

A week have passed since his birthday. Eren experimented on his quirk secretly to avoid his parents from worrying. Who would want to see their child hurt himself to activate his quirk?

Someone, but not his parents.

Now Eren in his room sitting at his desk trying to find some writing materials thinking about his plans for the future.

First, he analyzed his quirk Regeneration, it is a mutant/emitter type quirk that activates whenever he is injured.

Despite the power having no offensive application, Eren plans to gain complete mastery over his quirk and unlock the body 100% physical capabilities.

First selective regeneration, like prioritizing the healing of a specific part of the body as well as delayed regeneration. It would be cool but gross at the same time to trap his opponent in his body to prevent them from escaping using rapidly regenerating tissue, but thinking about it sends a shiver down his spine.

"If worse comes to worst, I'll do it! Damn!" Eren gritted his teeth.

Also the skill he noticed in his regeneration is the body ability to get stronger from every instance of wear and tear that muscle goes through. Another benefit of the Quirk is the more time he is injured by a certain kind of stimulus, his body is able to heal faster if struck again, while also taking less stamina and calories to do so.

Eren inferred that being injured in such a way, such as breaking bones often will eventually strengthen and stop breaking from high physical trauma.

"My my what an experiment to infer all of this."

"My body gets stronger the more I am injured, but I'm against being a punching bag and masochist. That's a Kaneki Ken[1] thing to do. But I got no choice if I want to get stronger. I need to stop being a scaredy cat If I want to be ready in facing strong villains when I grow up."

There are also flaws that I noticed in my Quirk that needs to be done something about. For example, I can still feel pain. Obviously. My body gets fatigued like every normal person with quirk, meaning I can be knocked out or get tired out from an extended period of combat. It's a no-no, this call for a need of close combat training while it's early.

"Yosh! Since I'm still young to train my body, I'll focus on martial arts to improve my close combat experience which is totally zero. I'll try to ask mom now."

I closed my notebook, walked out of my room then gone down the stairs. I see my mom preparing food using her quirk. It's my first time seeing her use it since I was born, not that I remember anything.

I approached her tiptoeing trying to prank her but I discarded my thought since I need to ask something who knows maybe she'll get mad, when I'm behind her I asked, "Is that your quirk mom?"

Mom was startled, "My God Eren! Don't do that!"

"Oopsie." I said trying to act cute.

"Nevermind. Who can resist the cuteness of my baby" then he pinched my cheeks.

I noticed that her hands are trembling.

"Yes, Eren this is my quirk. You see, I can manipulate things that are metal using only my eyes. If I close my eyes it will stop the telekinesis. Come come let's eat." She said.

I can see that there's a trace of uneasiness in her words.

"You have healthy eyes for someone who needs it to stay open always."

Then I asked, "Is there something wrong mom?"

"It's because I don't use it often baby. And why would you say there is something wrong? It's nothing Eren. Haha" she said while laughing and ruffling my hair.

"Okay, mom whatever you say. Let's eat!"

I sat at the chair then mom started setting the table and we started eating together.

After some time I finally got the initiative to ask her.

"Mom do you know someone who can teach me martial arts or stuff like that?"

Mom with shock written all over his face asked, "What's with the sudden enthusiasm today Eren?"

"More please!" Eren said after finishing his plate. Karla handed him seconds.

"I need to learn how to defend myself and I need to be proficient in close quarter combat. My quirk has no offensive capabilities at this moment that's why I need to practice it so when I start going to high school I can go toe to toe and keep up with my peers."

"Aww my little Eren has really grown so much he has dreams and aspirations now," Karla said smiling proudly.

"Hmp. I'm not a kid no more!"

"Mah mah okay Eren whatever you say. Just don't push yourself too hard. Your quirk is a mutation that's why you don't have one of our quirks. You're still young there's still time for improvement in the future."

"Hai Okachan! Oh now that I think about it. What's Otosan's quirk?"

"Thi-this."

"What's the matter, mom?" I asked, confused.

"Oh, nothing. His quirk is a transformation type. He can turn into something big! He's suited to be a hero. I don't know why he chose to be a researcher and a doctor."

"Woww! Strong! So are you mom your quirk is strong too!"

"Now now don't think too much. I'll ask your father about your request later."

"Thanks, mom! You're being modest. Hehe."

We spent the rest of the day finishing our lunch and doing household chores while I and mom talk anything under the sun. I asked to help her with his chores but she insists on declining.

"Don't forget to brush your teeth baby."

I go to the bathroom to brush my teeth, then after some time, I climbed upstairs to sleep just a little bit to past time because mom will call dad later.

I remembered all the training and experiments I've done to analyze my quirk and comprehend in this past week and it could be called batshit crazy.

"Arghh I'm so tireddd." Then I immediately fell sleep soundly afterward.

Later that day, waking up I find that dusk already arrived. I rubbed my eyes then stretched my arms upward. I look around my room for the clock and it shows 10 pm.

"Shit. It's already late." He said which is weird if you hear a child cursing.

Eren head to the restroom to wash his face and after sometime when his senses are all up. He walked out of the room and gone downstairs.

"Usually mom is still waiting for dad to come home at this time hour." Eren thought.

"Oh, Eren! You slept in the afternoon you'll have difficulty sleeping later now." Mom said then he pinched my nose.

"I'm just excited for news about my request from dad. Is he coming home tonight?"

"Oh, that! I think he won't be coming home tonight, another overtime. Your father agreed but he said you need to be careful and not punish yourself. You're still a child even though you are mature for your age."

"Yes! Alright mom, I'll be careful and take care of myself." I said with a thumbs up.

Thus began my journey to the top.
