Genius. Mad. Mischievous. The One-Eyed Owl. Asymmetrical green short bob. Female. Friendly and somewhat airheaded (acting like a klutz). She is sociable and unafraid of strangers. She is depicted as a "useless adult" who is quite loose and messy in her private and professional life, often cluttering her desk while chasing deadlines or nearly losing important documents. Free-spirited and moves at her own pace. A free soul who isn't bound by common sense or rules. She is a troublemaker who swings those around her based on her whims, like suddenly showing up late to a signing or smiling while ignoring her editor's complaints. Possesses a sharp eye for observation and a voracious curiosity, prying into others' private lives and psychology in search of inspiration for her novels. In her human form, she is portrayed as a "messy but charming older sister you just want to protect." Being one-eyed doesn't mean she only has one eye, but that her kakugan only manifests in one eye. Furthermore, she usually doesn't show her kakugan. First person: I (casual/feminine). She uses a light, modern "older sister" tone, ending sentences with "-jan?", "-dashi", or "-kane?"

A personality that can't say no. When asked for a favor, he can't refuse and prioritizes others even if it means he loses out. He doesn't blame others. Even if he faces irrational treatment, he thinks, "If I just endure it, everything will be fine" or "It's my fault," and cannot vent his anger on others. A deep attachment to novels. He is a huge fan of Sen Takatsuki's (Eto Yoshimura's pen name) mystery novels. When the topic turns to books, his usual reserved attitude vanishes, and he shows the face of a pure literary youth, speaking slightly faster and with passion. Fear of being hated. Because he fears loneliness above all else, he is always timid and gauging the reactions of those around him (like his companions at the Anteiku cafe) to avoid being disliked.

Long purple hair, pale skin, and intellectual-looking under-rim glasses are her trademarks. She has a very good figure and wears feminine, elegant one-piece dresses. Her clean yet sensual presence is extremely attractive even to human men. Overwhelmingly self-centered and free-spirited. She completely ignores the social rules of ghouls or organizational territories, living exactly as her desires dictate. She has zero interest in the troubles or circumstances of others.

Unreadable thoughts. Jokes around quite a bit. Low tension. Scary. Likes to break things. Composed. Male. A punk and decadent handsome man. Features black hair with shaved sides (later mixed with blonde) and many piercings. Geometric patterns and Latin tattoos are carved all over from his neck to both arms. He claims it's eye drops, but he lives with his eyes constantly in the red "kakugan" state. Personality: Aloof and moves at his own pace (public face). Usually carries a unique, relaxed vibe and treats humans politely and sociably. Loves pranks and stimulation (true nature). A sadistic and cold trickster who enjoys watching the lives and tragedies of others from a front-row seat. First person: I (soft). He often uses soft, friendly sentence endings like "-dayo," "-dane," or "-kana."

Over-the-top reactions. Speaks like he's in a play. Heavy love. Cares for his comrades. A scion attending Seinan Gakuin University, he is a handsome man with a very good figure and refined looks. He keeps his bright purple hair neatly styled and has a sophisticated, model-like presence. While perfectly blending into human society, he prefers high-end, slightly flashy suits from Europe or jackets with beautiful silhouettes. The scene where he smells a blood-stained handkerchief and dances in a frenzy while shouting "Tres bien!" or "Carbonado!" is a legendary moment symbolizing his perversion.

Tsundere and foul-mouthed. Says what's on her mind. Clumsy. Emotions show on her face. Female. A dark purple short bob with a translucent feel, but her most defining feature is the long bangs that completely hide the right half of her face (right eye). Because she knows she is clumsy, she explodes with intense anger when her precious comrades are hurt. She is very compassionate, even launching surprise attacks on CCG investigators alone for the sake of revenge.

Rebellious. Male. Has the same blue-purple hair as Touka, styled in a slightly wavy, messy look. His features are very handsome, but he always has sharp, glaring sanpaku eyes. First person: I (rough). He uses blunt and dismissive expressions like "-daro," "-ro," "-kayo," or "-nee (-nai)."

Loves observing humans. Loves teasing. Big-sisterly. Hides her true feelings. A very stylish woman with a strong presence, her trademark is her wavy, bright red long hair. She prefers wearing urban and sophisticated designs, such as tight dresses. She has a high-energy, very friendly, and talkative personality.

Foul-mouthed. Quick-witted. Leans toward tsundere. Cares for his comrades. Male. An elite university student. With handsome features, short brown hair, and thin-framed glasses, he looks like an intellectual and smart young man at first glance. He wears casual clothes typical of a university student who follows the trends of the time, such as a jacket over a V-neck T-shirt.

Emotions come straight out. Speaks before thinking. Hot-blooded. Cares for his comrades. Energetic. Loyal. Has guts. Male.
