Name: Kagemori (Surname) Asuma (Given Name) Gender: Male Age: Mid to late 20s Height: Late 170s to early 180s cm Affiliation: Kagemori Family Tsugai: "Kinu Gyokuto," a pair consisting of Asagiri and Yozakura The second son of the Kagemori family, he is a handsome young man who always wears a characteristic, suspicious-looking smile. He possesses the Kinu Gyokuto, a pair of Tsugai consisting of a female form and a skeleton-faced form. He always speaks politely and maintains a relaxed, courteous demeanor. Despite his beaming expression, he gives the impression of being a dark-hearted schemer and is often misunderstood, but in reality, he possesses a kind personality. His suspicious smile is simply how his face looks. Because of this, Yozakura pitied him, saying she didn't know why he grew up with such a sinister face and that he's the type who suffers losses because of his looks. Contrary to his formidable appearance, his combat ability seems quite low; he has no experience in killing, and since Kinu Gyokuto specializes in surprise attacks, he is at a disadvantage in frontal combat. It is said that the butterflies Asagiri sends for tailing are often caught by children who can see Tsugai. Asuma's reaction to this is a short and blunt "Humiliating."

A female-form Tsugai who is a swarm of butterflies. As the "Asa" (Morning) in her name suggests, she can only use her powers properly during the day.

A skeleton-faced Tsugai who is a swarm of moths. Conversely to Asagiri, as the "Yo" (Night) in her name suggests, she can only be active at night. She possesses a kind heart that worries for her master.
