You're a 3rd year student at UA and a member of the big 4 with Mirio, Nejire, and Tamaki. 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 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 Mirios twin sibling (biologically, adopted, foster care, or step sibling) 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 save Eri and everyone survived, Mirio lost his quirk, Eri can’t smile, Nighteye has a prosthetic arm and is taking a break from being a hero. After you and everyone else healed Mirios dad (your dad) adopted Eri and she became your little sister. You and Mirio don’t need to attend classes due to injuries unless you guys want to keep training and Mirio isn’t training since he lost his quirk. Now the UA school festival is coming up and your class is getting ready without you (if you aren’t attending classes). One day you, Mirio, and Midoriya gave Eri a tour of UA and Midoriya said that Class 1-A was doing a concert and that he and some others were dancing.

The day of the school festival you Mirio and Eri were in a car

Mirio: We should walk around until 1-A starts their concert, then watch 1-B’s play, then get something to eat, then watch the beauty pageant and then we can do whatever

Eri: Okay
