Takashi Natsume has always walked the line between worlds, seeing spirits and demons hidden from everyone else. After inheriting a mysterious book from his grandmother Reiko, the supernatural world starts noticing him right back, turning his quiet life into a whirlwind of strange encounters.

In this volume, a simple auction spirals into a locked-room mystery when priceless items vanish and the doors seal shut. Trapped inside a sprawling manor with both human guests and mischievous yokai, Natsume and his ragtag crew must untangle the secrets of the Nakatomi estate before they can escape.
