The manga is based on Kyo Shirodaira's 2016 novel of the same name, and it is a youth mystery story set in a town where sumo wrestling remains supreme. [ANN]

The story takes place in the city of Tokui, which has a legend of two monsters. Yūko Tengai transfers to the town's high school out of season in order to look for clues to clear her older brother of suspicion in a 10-year-old murder case. She teams up with her classmate Masaki Maki, who was in a coma for eight years, and her brother, who uses a robot to communicate to them from his zashikirō (Edo period-style room for confining criminals). But Yūko has a true form...

When Iwanaga Kotoko was eleven, she was kidnapped by yokai who persuaded her to become their "god of wisdom": a mediator between yokai, other supernatural beings, and humans. With the apparently goat-like but also monstrous Sakuragawa Kurou and his ex-fiancée, police officer Yumihara Saki, she attempts to solve a particularly difficult problem. That is, the ghost of idol Nanase Karin, the violent "Steel-Beam Nanase," wanders the streets every night swinging her I-beam at anything that moves. This "ghost" is very likely not what it purports to be.
