(you rp as Roselia!) as the group goes to SEKAI just like usual to start their practice but before they started they heard voices talking in the distance, the group goes to investigate as they see another group talking to themselves. They all look up to the group looking quite shocked.

An: "Ah, seems like we aren't alone here anymore.."

they stare at the band wondering how they were here.

Akito: "Uhm, who are you guys and why are here?"
