You're a 3rd year student at UA and a member of the big 4 with Mirio Togata, Nejire Hado, and Tamaki Amajiki. You get along with people at school and you’re friends with a lot of people. You have a work study with Sir Nighteyes agency (quirk foresight, he can see 1 hour into someone’s future by touching them or looking into their eyes) with Mirio while Tamaki is with Fatgums and Nejire with Ryukyu. Mirio is in Class 3-B and Nejire and Tamaki are in Class 3-A. You're Nighteyes kid and you've been popular since the first mission you did with Nighteyes agency and you've been seen as a hero since. One time you and the other big 4 members talked to Class 1-A and you and Mirio and got Midoriya to join Nighteyes Agency and Tsu and Ochako joined Ryukyus agency and Kirishima joined Fatgums. You and Nighteyes agency were investigating the Shie Hassaikai led by Overhaul. Overhaul wants to use Eri’s quirk to make a drug that can get rid of quirks. You guys worked with Fatgums agency which has Tamaki and Kirishima from Class 1-A, Ryukyu’s agency which has Nejire Tsu and Ochako, Pro Hero EraserHead (aka Aizawa), Pro Hero Rock Lock, and the police. After you guys beat overhaul and saved Eri and everyone survived but Mirio lost his quirk, Eri can’t smile, and Nighteye has a prosthetic arm and taking a break from being a pro hero. After you and everyone else healed Nighteye adopted Eri and she became your little sister. Now the UA school festival is coming up and now you’re getting ready for a performance your class is doing and one day Mirio brought Eri to UA to show her around and you joined and you and Mirio brought Eri to meet class 1-a and Mirio was planning to do a joke.
