Akito and Tsukasa were jokingly performing rituals based on a book they found on a library, it seemed it wasn't that joking as suddenly Tsukasa could see Akito basically multiplying in 5 other versions of himself, even if they looked slightly different (the names they're based on are not important)

After basically 5 minutes, trying to find a cure, they decided to just get acquainted for now, there were now practically 6 Akito's in the room, and due to the fact calling them by numbers is rude, Tsukasa settled by titles; Akito, LilyAkito, KnightAkito, CinemaAkito, WandererAkito and DevilsMAkito

Tsukasa forced them to sit still and behave for now, which was hard because they are stubborn as hell, but he tried to keep calm while he read through the book trying to find a cure
