During a month Inko, Izuku's Mother, would go to the hospital visit her son in coma, she would cry all the time until visiting time was off.
Katsuki at first acted like shocked and sad, only for his mother not notice that it was her son fault.
All might told Tsukiachi that he only told the boy that being a hero is dangerous even with a quirk, and he should try to be a police officer, what was true but not at all.
3 months after the jump Izuku woke up from the coma, but the result wasn't the best, when the nurses arrived Izuku, the quirkless boy, activated a quirk in the middle of one panic attack, leaving one nurse burnt until there were only ashes, the boy went again to sleep, but this time were the nurses of placed him I sleep.
Shota Aizawa Pov
Uh what a pain, I got a call from XXXXX hospital, apparently a quirkless kid that tried to jump of the roof woke up from a coma and manifestes a quirk while having a panic attack leaving one nurse burnt to ashes.
I'm finally in the kid's room, he should wake up in 2 or less minutes.
"so what really happened Doctor Ujiko?"
"apparently this boy, who was quirkless the first time I meet him, when he was 4 years old, after jumping developed a quirk. I don't know what he had endured until that day, but what happened was the same that torture, because this is a trauma inducted quirk." interesting so there was really a background story involving that Katsuki Bakugo and Toshinori.
"What really is his quirk of u don't mind telling me."
"well from what I have seen and my quirk tells me, this boy has a fire type quirk, he produced green flames, the drawbacks I can't find all, but what I did was that he goes insane if he overuse it" insanity uh.
"oh and he also had this notebook, take a look" 'hero analysis for the future nº13' this book was burnt but it had information on heros, very detailed weakness, fighting styles and everything, I can't let this kid go into a villain path, I'll recommend him to UA.
