Adaptation of the third novel of Natsuhiko Kyogoku's "Kyougokudou Series."

In 1950s Tokyo, only the Rose Cross Detective Agency can tackle the cases that the police won't touch. Enokizu is an eccentric private eye with psychic abilities, and Chuuzenji is a surly used book store owner with an encylopaedic knowledge of obscure trivia. Together with their associates, they seek justice for the victims.

Stand-alone side story to the Kyougokudou series, beginning with Ubume no Natsu.

A bizarre set of mysteries have befallen the Kuonji household. Kyoko Kuonji is said to be with child for the last twenty months, and her husband Makio disappeared a few months prior to the prgnancy. The odd circumstances have left the family with no one to turn to for help, until a freelance writer asks his exorcist friend to take on the case. The catch—the exorcist does not believe in ghosts. To Akihiko “Kyogokudo” Chuzenji, the supernatural is as much metaphysical and mental as it is unearthly.
