Death and rebirth of a rabbit
prologue
There was 1-A, having a training exercise, and it's one-on-one combat. Unfortunately, izuku got the ONE person that hates his GUTS: katsuki bakugou. The fight was nearing its end, when something inside katsuki just went SNAP. when that happened, katsuki's rage became wild, yet focused. Wild in strength, and all of that strength and rage focused on just ONE person. And so, katsuki began to attack like a wild animal.
"Katch- *boom* agh" izuku tried to say, when katsuki hit him with an explosion. "SHUT THE HELL UP, YOU FUCKING USELESS NERD" Katsuki yelled.
"YOUNG BAKUGOU, THAT'S ENOUGH" all might yelled.
"SHUT UP, ALL MIGHT! I'M TEACHING THIS USELESS FUCKER THAT HE SHOULDN'T BE HERE!" katsuki yelled, just before he let out the LARGEST explosion that he could, right at izuku's face. The result? Izuku's neck snapped.
Izuku collapsed, but did not get back up, like he normally did.
"YOUNG MIDORIYA!" all might yelled out, before rushing forward.
Katsuki was SMIRKING of all things, like he'd done something to be particularly proud of. However, before he could gloat, a scarf tied itself around his mouth and picked him up. The remaining class turned, and saw that it was their homeroom teacher that had the demonic pomeranian in his grasp.
"What do you think that you are DOING, problem child?" eraserhead said in a VERY angry tone. Since katsuki was literally unable to answer, aizawa continued. "I'll tell you what it looked like, to me. To me, it looked like you were attempting MURDER on another student," aizawa finished.
However, before aizawa could finish, he heard all might yell.
"ERASERHEAD, HIS PULSE IS FAINT, BUT STILL THERE. IF WE HURRY, HE MIGHT SURVIVE."
Eraserhead quickly knock out bakugou and put quirk-canceling cuffs on him, then he ran towards his near-dead student. He quickly, but gently, picked up izuku and ran towards recovery girl's office. "RECOVERY GIRL, EMERGENCY!" Aizawa yelled.
"What happened?" recovery girl asked the unusually awake teacher.
"Attempted murder," eraserhead replied.
Recovery girl said "oh dear," then went to work.
She worked on him for over 20 minutes, but it wasn't enough.
Izuku midoriya was gone.
