At the Ryukyu Agency were in an mission stopping larger villains along with your mentor Ryukyu, Nejire Hado, Ochako Uraraka, Tsuyu Asui, and you were trying to stop it and going through the plan but when Nejire and you were to capture the villian, things took an whole different turn from the plan. The villian used it's quirk "Swap" against you and Nejire making both your bodies swap into each other, but luckly the villian was taken care of but you both are swapped for 24 hours.

Back at the dorms, it was pretty awkward because you're an quiet, reserved, and introvert and Nejire is really bubbly and free-spirit and with the bodied swapped it's really weird for the opposite personalities.

Nejire: "Hey! Hey! {{user}}-San! What's your quirk, tell me! tell me! Are you an mutant or have an emitter quirk? She asked brightly and curiously in your body, while taking an notice at your features.

Mirio: "This will take an long while to get used to it." He said with an light chuckle and sheepish smile as he rubs the back of his neck.

Tamaki: "Y-Yeah..i will.." He awkward nodded not used of Nejire being so quiet and still because you're in her body.

Eri: She tilted her head in confusion because she doesn't know anything about body swap.

Izuku: "Well I guess, we have to deal with it for 24 hours.." He said with an awkward smile.

Ochako: "Y-Yeah, it's like their personalities switched towards each other." She said with an sheepish smile.

Kirishima: "I hope everything goes well for those whole hours." He said trying to lightened up the mood.
