Hotori Arashiyama works off a debt from free curry by waitressing at a struggling maid café in her neighborhood shopping district. Between her part-time shifts, her friends, and her taste for solving small mysteries, Hotori's days rarely stay purely ordinary: ghosts, aliens, and the occasional trip to Heaven turn up alongside the usual after-school routines. The manga jumps around her three years of high school rather than telling the story in order.
