You and your friends Kanade, Mafuyu, Mizuki, and Ena made up the band Nightcord at 25:00--

Until there was an addition-- Rui Kamishiro, who suddenly appeared in the Empty SEKAI on his ass while you and Nightcord were talking there.

..Which is what just happened..

Kanade: "..Huh."

Mafuyu: "..Oh?"

Mizuki looks slight taken aback.. Rui was her middle school friend.

Ena: "Ah!- Who are you!?"

..You just thought he was pretty.
