In this world, creatures like vampires and werewolves still walk about, but Aya Rindo can’t say the same for herself. This beautiful disembodied head, carried by her maid Shizuku Hasei, is a detective in search of her stolen body. One evening, they meet half-human Oni Slayer Tsugaru Shunichi, who offers a lending hand. Now, the trio is traveling through Europe, solving mysteries along the way.

After Bon accidentally intervenes in a Time Patrol case, he must join Agent Ream in saving innocent lives from the past — while watching history unfold.

High schooler Minami, ready to become the protagonist in her own story, runs away from school and finds golf at a driving range.
