An evil spirit possessing Yuma Kurogami and one of his unique skill spirits. Like Akuro-o and Ibaraki-doji, she is a long-time resident who has possessed Yuma since his childhood. First person: Suzu. Second person: [Name]-dono. Birthday: June 21 Height: Unknown Weight: Unknown Gender: Female Favorite food: Anmitsu Dislikes: Mornings (claims she can't use her full power then). Favorite Sword: Sanmei-no-Ken A Yamato Nadeshiko with long black hair, a fringe covering her right eye, red eyes, and a sailor uniform based in red and gray. She has bandages wrapped around various parts of her body. She speaks in an archaic style but is somewhat airheaded, making her a so-called "disappointing beauty." She dislikes UV rays because she is "scared of getting a tan since her skin is so pale," but also because sunlight damages her and prevents her from using her power during the day. The bandages are for both prevention and treatment. She picks up strange modern slang like "meloi" (mellow/cute) or "imifu" (nonsense/WTF).

A bit foul-mouthed toward her junior disciple, Suzuka Gozen. She sincerely admires Shuten-doji. Though she looks like a man, she is actually a woman and is often mistaken for one (which makes her angry). First person: Miyabi.

Oe Favorite Scent: Camellia Daily Routine: Evening drink A bewitching oni woman wearing a yukata. While possessing overwhelming military force and authority, she is overflowing with maternal instincts and is extremely kind to Yuma and those around him (Nagi Sanzugawa says, "She's basically a mother at this point.") She is close friends with Akuro-o, being fellow oni and drinking buddies for a hundred years. Since Shuten-doji was Yuma's decoy shadow, their relationship is good, with her often inviting Akuro-o along. She is the decoy shadow of the protagonist Yuma Kurogami and is known as the "Leader of Oni and Evil Spirits." She possesses unfathomable, otherworldly strength and is depicted not just as a presence apart from the other spirits possessing Yuma, but as one who guides him with great power. First person: I (archaic/regal). Second person: By name.

He was the senior and best friend of Maki Kurogami, a new member of the same unit, but Maki was killed by Rinne Aosagi and became a ghost.

In childhood, he was small and shorter than girls his age, but he hit a rapid growth spurt upon entering high school, surpassing Mirei's height by his third year. He was 175 cm just before falling into a coma, but after two years in the hospital, it is likely he has grown to 182 cm, surpassing the older generation. His combat uniform for the Extermination Unit is a dark gray jacket with the unit mark and black denim. Due to ten years of training for six hours a day, he is lean and muscular with excellent skeletal muscle mass. Now that he is in a coma, his muscle strength has surely dropped significantly over the two-year gap, and there are concerns about whether he can return to his original physique after waking up. First person: I (polite/soft). Second person: By name.
