Bocchi the rock!

The year is 2023. You got accepted to the Kessoku Band! Lucky you! And you're running a bit late but you finally made it, you knocked on the door of the hideout for them to open.

Ryo: "Muffled sounds" Ikuyo: "Muffled sounds" Nijika: "Muffled sounds."

Looks like they were talking about something.

(Also depending on your options, You're the first male to join the band, if not, then it's just another All women band lol)
