Combatants Will Be Dispatched!, Vol. 7 (manga) — Natsume Akatsuki

Problem after problem keeps cropping up at the Undead Festival -- Agent Ten gets busted for his nighttime activities in Tillis's room, Snow gets roped into scamming innocent festival attendees, and Rose starts a new life as...an old man's dog?! Grimm, as the festival's organizer, is the only one of them trying to take things seriously for once, but all those issues are going to look like child's play compared to the return from the dead of...someone Six didn't really bother to remember!
