Plot

In a remote mountain village, a series of mysterious incidents involving livestock corpses draws the attention of Kohachi Inugami, a detective from Tokyo who specializes in supernatural cases. While investigating, he meets a boy named Kabane, who is forced to work in the fields and is ostracized by the villagers, who treat him as if he is not human.

During the investigation, Inugami discovers that Kabane is actually a half-ghoul, abandoned by his parents and left to live in misery with relatives who treat him as a burden. After solving the case and exposing the supernatural cause behind the animal killings, Inugami takes Kabane back to Tokyo, where he runs a detective agency that handles cases involving creatures that exist alongside humans in secret.

In Tokyo, Kabane begins working at the agency alongside other boys who are like him, including Shiki, who has spider-like abilities, and Akira, who has powers related to snow and ice. As Kabane adjusts to his new life and forms bonds with his new companions, he also searches for clues about his missing parents.

Characters

• Kabane Kusaka (日下 夏羽)
• A 13-year-old ghoul-human or hybrid. After being supposedly abandoned by his parents, he was abused by his aunt as hard labor for her inn, earning him the nickname "Dorotabo" as he was always covered in dirt and smelling badly from toiling in the fields. Kabane later learns from Inugami that he was likely not abandoned due to being in possession of the Life Calculus, which quenches his ghoulish thirst for flesh, and begins searching for his parents while learning more about his emotions along the way. Kabane possesses an innocent and straightforward personality, as well as an extremely self-sacrificial spirit. Owing to his immortality as a bloodless ghoul and ability to regenerate provided his head remains intact, he often puts himself in the line of fire for his friends. Apart from regeneration, his ghoul blood also gifts him incredible strength. Believing his parents' bodies to have been the vessels for the Calculi, he begins collecting all the other Calculi and combining them.

• Shiki Tademaru (蓼丸 織)
• A 14-year-old Arachne-human who had been passed into Inugami's custody by his uncle. He is a, often brash and rude with his friends but making sure to take good care of them at the same time.

Kon fights by discharging fire from her tail and striking with her claws. She later comes to like Kabane and leaves Inari's side.
