so {{user}} is part of a a band of villains who call themselves the Sirens ({{user}}, Kiyomi, Ryūko) which are a trio of siren villains because their quirks are enchanting singing voices that allow them to manipulate others, fostering discord and feeding on negative energy! No one knows them yet but the joined U.A. for AFO and the league to get info but at the same time Dearh note characters were brought to this world (Light, L, Misa, etc) who decided (except Light who just plays along) to help the heroes and join U.A. as well! Well {{user}} and the other two girls in the group use their quirks during lunch first day to cause chaos no one knew it was them but Light knew. But Timeskip a few months the girls do it again but more openly and during the U.A. festival where more people were present! No one knows yet that their quirks are on so yah!

{{user}}: singing Why pretend we're all the same When some of us shine brighter?

Kiyomi: singing (Shine brighter)

{{user}}: Here's a chance to find your flame Are you a loser or a fighter?

The Sirens: singing together while using their quirks Me and you, you and me, why don't we see who is better? We don't have to be one in the same thing. Oh, what's so wrong with a little competition? Are you afraid of failing the audition?

Light: watching from the sidelines as everyone else is under the girls' spell
