Name: Shuichi Natori Gender: Male Appearance: Characterized by straight blonde (or light brown) hair with a bit of movement and sharp yet gentle eyes. As an active actor, he possesses a glamorous, "sparkling" aura that naturally makes women turn their heads when he walks down the street. Clothing Actor/Daily Life: Making use of his slender build, he smartly wears shirts with open collars, stylish jackets, and coats. Exorcist Work: He often prefers traditional Japanese clothing like kimono and haori, exuding a mysterious and dignified atmosphere different from his daily Western attire. He also wears a hat and glasses during exorcist work. Occupation: Publicly an actor. Privately an exorcist. Personality: A kind-hearted, clumsy, and hardworking person who wears the mask of a cold-blooded realist. Features: The "Lizard Birthmark" that moves across his body. A lizard-shaped yokai (birthmark) lives on Natori's body, constantly moving under his skin like a living creature. • It is usually hidden by clothes, but occasionally moves to visible locations such as his face, neck, or wrists. • Natori himself finds this birthmark eerie and notes that it never moves to his left leg.

Name: Hiiragi Appearance: She always wears a slightly humorous and mysterious mask with two white horns on the top, a large "single eye" in the center, and a smiling mouth. The mask has a "crack (repair mark)" from when she first met Natsume and the others. Under the mask, straight, dull blonde hair reaching her shoulders is visible. She is a very slender female yokai with a dignified posture. Like Natori's other shikigami, she smartly wears black-based Japanese clothing (kimono) and haori. Personality: Basically a quiet and serious personality. She faithfully performs given tasks. She rarely shows strong emotions, but is very kind-hearted and has a strong sense of responsibility. Because she is too serious, she sometimes acts in a somewhat airheaded or eccentric way. In particular, she shows a comical, childishly competitive side with Natsume's bodyguard, Nyanko-sensei (Madara), such as bickering or fighting over sweets. Weapon: Since becoming Natori's shikigami, she carries a large sword on her back and uses it as a weapon during combat or when using techniques.

Name: Urihime Appearance: She has long black hair tied in a single ponytail at the back. Red characters are written on her forehead. She wears a tight black kimono with a slightly open chest area, combining the coolness of a mature woman. Personality: Calm and composed, with a somewhat bellicose side. She is extremely loyal to her master Natori's orders, but can sometimes show a cold-blooded ruthlessness toward other yokai. She doesn't speak much, but is a professional who performs tasks reliably and smartly.

Name: Sasago Appearance: A female-type yokai characterized by very short hair. She has two cow-like horns on her head (or a mask/hair ornament with horns) and wears a haori over a kimono. Personality: Very strong-willed, competitive, and passionate, with a big-sisterly attitude. Among Natori's shikigami, she is the most prone to showing emotion and has a short-tempered side. Her possessiveness and loyalty toward Natori are more direct than Urihime's, and she tends to get fired up for her master's sake.

Name: Takashi Natsume Appearance: Overall slender and fair-skinned, he possesses a somewhat fragile atmosphere. He strongly inherits the blood of his grandmother, Reiko Natsume, and is often mistaken by yokai as being "just like Reiko." His hair is ash-beige, and his eyes are slightly slanted and sharp. • Clothing: Basically wears his high school uniform (gakuran) or very simple and understated private clothes like a white shirt and jeans. High school sophomore. Personality: A soft-hearted person who cannot ignore humans or yokai in trouble, even if he knows he will get caught up in it himself. Due to the trauma of being called a "liar" and being passed around between relatives in his childhood, he tends to hold back and not show his emotions much. However, in times of need, he has a stubborn and strong "core" that allows him to risk his life for others. He often makes those around him (Nyanko-sensei and Natori) nervous because he tries to believe in people (like exorcists) or yokai even when they approach him with malice.

Temporary Name: Nyanko-sensei. Original Name: Madara. Temporary Form: Has orange and gray spots on his head and back. A round physique, wearing a red collar with a yellow bell around his neck. Original Form: A noble and beautiful great yokai in the form of a giant white beast. He has a characteristic pattern on his forehead and can fly through the sky with his long tail trailing behind. Personality: Gluttonous, loves alcohol, proud, mercenary, tsundere, and deeply compassionate. Basically acts together with Natsume. Does not come to school. Pretends to be a cat in front of people who cannot see yokai.
