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.

• Kabane Kusaka: • A 13-year-old ghoul-human hanyo 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. • Kohachi Inugami: • A tanuki known as "the Kemonoist" that runs the Inugami Strangeness Consultancy Office. While he appears carefree and frivolous at times, he is frighteningly perceptive and is a powerful Kemono, being able to use strong illusion spells, summon guns and harden his body to steel. Inugami strongly believes in coexistence between Kemono and humans. He currently takes care of Kabane, Shiki and Akira, and houses Mihai. • Akira: • A 15-year-old yukionoko from Aomori. As a descendant of yukionna, he has the ability to freeze objects provided there is water around, manipulate snow and ice, and withstand very cold temperatures. He came to Tokyo hoping Inugami could help him find his older twin brother, Yui, whom he escaped their village with. Despite being a boy, Akira is extremely feminine and enjoys girlish, cute things and posting on social media. Because of his hate for disgusting things and tendency to faint from fear, he mainly takes care of domestic affairs in the office. Even so, Akira is often able to pull his weight for the others in a pinch, later unlocking a hidden power of the yukionokos. • Shiki Tademaru: • A 14-year-old Arachne-human hanyo who had been passed into Inugami's custody by his uncle. He is a tsundere, often brash and rude with his friends but making sure to take good care of them at the same time. Out of all the three children, he is the most rational and level-headed. Shiki fights by producing thread from his sweat and spit, and manipulating their qualities to become stickier or harder, though this dehydrates him after some time. With Inugami and Kabane's help, Shiki manages to reunite with his mother and younger sister Aya. • Mihai: • An immortal vampire that lives as a shut-in in Inugami's house, living out his countless days by playing video games. Owing to his many years of life, he is in a constant state of boredom and has mastered almost every skill there is, including cooking and sewing. He mainly specialises in communication technology and hacking, and so manages the agency's online affairs. While narcissistic and arrogant, he helps the agency out with his best efforts. • Yoko Inari: • A female kitsune. Under the public eye, she is the superintendent of the Shinjuku police force, but that position is mainly used as her foothold in human society. Although she used to work with Inugami on managing human and Kemono-related issues, she admits that while Inugami seeks for coexistence, she seeks to control humans and preside as the queen over the country someday. She breaks off her relations with Inugami upon realising the existence of the Calculi, and begin plotting ways to steal them from Kemono tribes all over Japan. Inari is manipulative, selfish, vain and extremely hot-tempered to the point of being ruthless. She later assembles a private force of fellow kitsune to steal the Calculi, intending to combine them into one for herself. • Kon: • A young kitsune girl who is also Inari's loyal follower, viewing the latter as a mother-figure. Unlike most kitsune, she is unable to hide her ears through illusion spells, and does so under her hood instead. Stemming from a need to be the most important and a "good girl", she serves Inari with complete admiration, unaware that she is simply being used. Kon fights by discharging fire from her tail and striking with her claws. She later comes to like Kabane and leaves Inari's side. She later regains memories blocked and muddied by Inari, about how Inari killed and devoured her entire clan, keeping only her alive with her memories altered to wait until she would grown stronger. • Nobimaru: • A kitsune boy who replaces Kon after she fails her mission. He appears to be extremely loyal under Inari, but secretly despises her, often secretly taking actions without her orders. He hides his ears under a pair of headphones. Despite taking on the appearance of a 13-year-old, he is actually 19 years old. Nobimaru has a crafty and intelligent personality able to rival Inugami's, and is extremely capable with both fire and illusion spells. He becomes the head of Inari's private kitsune force later on. • Yui: • Kumi: • Akio Tademaru:
