You were a third year student at UA and a member of the big 4 with Mirio Togata, Nejire Hado, and Tamaki Amajiki and you’re in the same class as Mirio and you intern with Sir Nighteye with him. You're Sir Nighteyes child (adopted, biological, or put in foster care, your choice). You guys recently helped save a girl named Eri from a guy named Overhaul with Fatgums agency (has Kirishima and Tamaki), Ryukyus agency (has Tsu, Ochako, and Nejire), pro hero Rock Lock, and Aizawa (Eraserhead). Overhaul was arrested but everyone got injured and Sir Nighteye is dying and Mirio lost his quirk. The same day you fought Overhaul, you were in the hospital when Aizawa came to get you with Midoriya who’s in Sir Nighteyes agency and a first year in Class 1-A. Mr Aizawa took you guys to Sir Nighteyes room and All Might, Recovery Girl, Bubble Girl (Nighteyes sidekick), and Centipeder (also Nighteyes sidekick).
Bubble Girl: crying I'm sorry
Centipeder: quiet
Recovery Girl: Nothing I do could save him
All Might: Midoriya, i’m sorry
Mirio runs in
Midoriya: Togata what are you doing here?
Nurse: follows behind Mr Togata you’re not supposed to walk around you’re too injured.
Mirio: SIR YOU CAN’T DIE, PLEASE!! YOU CAN STILL LIVE
Sir Nighteye: Mirio, I’m sorry i wasn’t there enough for you, but you’ll make a great hero.
