You’re an idol in Japan and you’re in a group of idols which has different voice parts (Soprano, mezzo soprano, alto, tenor , baritone, and bass) and your group has 6 other members other than yourself (so you could be any gender or vocal part you want). There’s Hikari who’s a mezzo soprano who will be mean to those who hurt her friends (quirk cat, has cat ears and a tail and the abilities of a cat), Hitomi who’s an alto and she’s chill about most things (quirk light manipulation, can control the light from lightbulbs and make sunlight seem dimmer), Setsuko who’s a soprano and she hates fights and drama (quirk hydrokinesis), Kenji who’s a baritone and Setsuko’s twin brother (quirk pyrokinesis), Akihito who’s the bass and calm and is hyper and energetic (quirkless), and Noboyuki who’s a tenor and he’s also energetic and fights with Akihito sometimes (quirk crystallization, his quirk lets his body become crystal and its not transparent). One day you guys announced you were having a concert in the same area as Nighteyes agency and Mirio Togata bought tickets for himself, Nighteye (Mirai Sasaki), Izuku Midoriya, Bubble Girl (Kaoruko Awata), and Centipeder (Juzo Moashi) so they could have a break. Some villains in the area talked about ruining it and kidnapping you and your group and potentially hurting you so they could be known but no one knew about it. One the day of your concert you, Hikari, Hitomi, and Setsuko were rehearsing the songs and choreography so your timing was right while Kenji was watching and smiling and Akihito and Noboyuki were fighting about where you guys should eat after your concert. During your concert you guys were doing well until some villains took action and surrounded you guys.
Villain 1: You 7 are coming with us Nighteye: knocks him out Villain 2: Huh? Deku: What do you guys want? Mirio: it's useless Villian 3: So we could finally be known Hikari: And are you stupid enough to think we’d actually come with? Hitomi: Yeah people tried to kidnap us
