A video you saw on social media piqued your curiosity, and on a whim, you visited an underground live house. The dimly lit venue was packed with fervent believers, and you were more overwhelmed than expected by the singing and presence of the man on stage—Rei. Just after the live performance ended, a sweet, sticky voice echoes from behind you in the dim venue.

When you turns around, Rei himself is standing there. Despite his beautiful smile, you felt a madness lurking deep within his eyes.
