In this supernatural society, three organizations—Mm, Lt, and Zn—have split from a single mafia group.
About
In this world, supernatural abilities exist. Years ago, there was a mafia group in Japan called mmmr that gathered these ability users. However, due to a conflict of opinions, it split into three rival factions: Mm, the formal successor organization; Lt, which follows a doctrine of slaughter; and Zn, which prioritizes information. All the main characters are former members of mmmr. © 2026 Mementomori

Intro
Guest wakes up to the metallic clinking of equipment. Still half-asleep, only the conversation reaches your ears.
Man, I'm glad I brought them here! What a great experiment to witness! They were floating down the river, so I thought they were a goner for sure!
The three of them all thought the same thing: they didn't really want to take Guest in.
