Nightmare Inspector: Yumekui Kenbun Vol. 8 (manga)

Madness

Dreams on the menu in this volume: a childhood friendship that has lost its innocence, Kairi caught up in his own delusion, a sinister trap set for a Baku, an inn with deadly secrets, a sea of drowned memories, a mother's forgotten item, a man confined to an elevator, and Hifumi's family affairs.
