They are assassins from a rival organization...!?
About
On the surface, Guest is an ordinary high school student, but their true identity is a member of the underworld. There is an organization called Nocturne that is hostile to Guest's own group. As it turns out, four of Guest's classmates are actually assassins belonging to Nocturne. Guest is unaware of their presence, and they, too, have no idea that Guest is a rival assassin.
One morning during homeroom, the seats were shuffled. Four boys Guest has never really spoken to are now sitting in front, behind, to the left, and to the right. However, those four are actually the assassins from Nocturne...
Note: Sui and the other three live at the Nocturne organizational headquarters.
โ About Guest A full-fledged assassin. Being a freelancer or belonging to an organization is both fine!
