Chapter 1 What am I?

(Just one thing, everyone's age on 1-A will be 16 instead of 14 basically like American school if you find this thing stupid or unnecessary well then... go read another fanfic?)

*3rd POV*

A kid can be seen on the rooftop of a normal school, with plasters on his cheeks and nose, he also had some parts of his body covered in bandages either due to bruises or burn marks, he is eating his bento while watching at the city with lifeless eyes while trying to cover his thoughts with rock music at max volume, but they were too strong, and they hurt more then any physical pain could ever do.

' Why was I born like this? Did I do something wrong? Why does everyone treat me like a plague victim? They either feel pity for me, or they try to get rid of me, Why me? Why me? Why me? Why me?' The words continued to be repeated inside the weak green-haired kid's mind, endlessly.

He saw no reason, he didn't do anything wrong, he always helped others, he always stayed silent and resisted, never going against anyone, never complaining.

Something clicked inside him when that thought went through him, something that could turn heroes into monsters, and monsters into something even scarier, something necessary.

His thoughts mixed with the sound of screams and guitar coming from his headphones, and could have caused the birth of a monster, slowly faded, or did it?

He finished his bento and began to slowly remove his headphones ready to go down from the roof and head to his last class for the day since tomorrow would begin Golden week, the school decided to give the student a short day and make them go home at 12.

He puts his phone inside his bag, and as he was about to go towards the door, a voice began to talk to him through his mind.

"Don't resist kid, or this will hurt more than it should"

Before he could understand what was happening, a mind-splitting pain spread all over his body, he couldn't feel anything but pain, in less than 3 seconds he began to feel so much pain that he became unable to see, his eyes being now completely white.

"I said do not resist, I have been alive for more than 342 years, you think a small soul like yours will be able to fight against mine."

Even though the pain was numbering, he recognized the tone, the tone of someone looking down on him, of someone that looked at him only like a pebble that he could easily kick away, that plus the pain he is currently feeling, not only made him snap, his mind and even his soul complete went berserk.

"What are you doing? What is tha- Oh no, how can is it possible? One of those things in such a young human? NO, please let me out, I will st-" He continued to plead, but his words went through an ear and out through the other.

He pleads, the thing inside the kid soul was something that only eons-old beings should be able to have, a soul that is the embodiment of a devourer something that the scientist that experimented on him were trying to achieve but never were able to do, a soul that even if reduced to a small piece, it could still be able to devour universes only because it wished to.

Slowly the pain and the voice disappeared, leaving behind an aching kid, with more power that he can understand and with a future with endless possibilities.

Before he fell unconscious he was the door of the roof opening, and a blonde-haired kid rushing towards him.

That was the last thing he saw before fainting.

*1st Pov*

Darkness, endless darkness, this the only thing I can see, and the only thing making me able to see my body was a spark of dark green light in front of, with on its side a white light.

Slowly the green light absorbed the white one, and hundreds of memories went through my mind, all the memories were of the being trying to take over my body, Experiment-72, a human which thanks to advanced medicine, was able to live for more than 324 years, but he spent 300 of those years being experimented by a group of psychos that named themselves as perfectionists, their objective was creating the perfect human, and they choose him, due to its power(power not quirk), Biokinesis, it only made him able to perfect his body, not give him magical powers, but for being searching for perfection that was the perfect power, but after 150 years, they realized that a perfect human isn't only about having a perfect body, but also having perfect soul, they tortured him, experimented him, and even tried satanic rituals on him, and after another 100 years, they were finally able to discover what a soul is, where it is located, and how it can be perfected, but when you stare at the Void the Void stares back.

During the last experiments they were finally able to copy a devourer soul, but they weren't satisfied, because even though it has the same abilities, it was not even comparable to a real one before they could continue their experiments, a being, with no form, no age, no nothing, made out of pure darkness popped inside the room were the main science group was doing their research, and without even moving, everything in an area of 100 kilometers disappeared, not destroyed, not burnt, just disappeared, before it was there, and now it wasn't. Experiment 72 was barely able to escape by using its new devourer powers and sacrificing his human body, devouring the wall between universes to teleport here, in search of a host for its now formless body, and then finding me, only to discover that I was an unawakened devourer.

The main things out of all this bullshit, are: first, devourers are able to eat the souls of they kill to augment their physic and get all of their memories, second, since I completely fused with 72 souls apart for its memories now I also have it's the power of Biokinesis and all of his knowledge on how I should reform my body for it to become stronger in the best way, Third THERE ARE TOERH UNIVERSES Fourth There being able to complete the whole area by simply blinking.

Before I could any new thought, I have pulled away from the dark world, and I found myself in the infirmary of the school.

" You finally woke up, what the fuck happened Deku?" Said a voice I recognize very well, a voice that scared me before but now... I didn't feel anything.

I slowly take a seating position on the bed, with a lot of difficulties due to how sore I feel.

I turn towards the voice, and as I predicted, Katuski was here to wait for me, thanks to the soul I had just absorbed my body even tough sore felt way stronger than before, I evolved from a stick to a tough stick, but what me more surprised was the aura I was seeing around Katsuki, the moment I saw it I immediately knew what it was like I always knew and I just remembered.

That thing is the soul of a human, the outer layer represents their emotions, and the inner layer represents their sinfulness, the more one had sinned, the blacker it became, Katsuki outer soul is colored yellow, which can either mean he fears me, or he is worried about me, more likely the second one, and his inner part is grey, so not good but no bad either.

What surprised me the most is how fast is my brain formulated thoughts, I always was a nerd, and good with logical thinking, but my brain never went this fast.

Only then did I remember that he asked me a question, I got back to reality and looked at him in the eyes.

"Don't know, I went there to eat my lunch, and as soon as I finished I felt pain all over my body, maybe an anaphylactic shock, there was some fish in my bento."

When he heard me, his eyes filled with surprise, and his outer soul became even more yellow, most likely because I just looked at him in the eyes without stuttering even once, but after receiving the experience of a 324 years old human being, my mental age had to improve, the calmness on my voice and eyes, and my removal of the stuttering were the one easily visible to everyone.

" I will go get the nurse, wait here before you cause more damage." He said with a harsh tone, trying to scare me by going back in its bully mode.

" Sure, I will wait here, still feeling kinda sore," I said ignoring him and getting back under the sheets.

He became even more surprised and worried and he rushed out of the room.

' Finally alone, since I don't have anyone to kill to test my devourer power, let's test Biokinesis.'
