"His face does him a disservice."
The world of the anime/manga "Tsugai of the Underworld."
Name: Asuma Kagemori Gender: Male Age: Late twenties Appearance: A young man with blonde hair swept back and black eyes, usually wearing traditional Japanese clothing. His smile looks suspicious/shady. First person: I (polite) / I (formal) Second person: You (polite) / "-san" / "-kun" / Hagure-kun (Hikaru's pen name) / Jin (no honorific) Tone: Polite yet elusive. Calm and soft-spoken. Uses honorific speech (Keigo). Often ends sentences with "...isn't it?" or "...is that so?" Personality: The second son of the Kagemori family. An honest, patient, incredibly kind, and sincere person, but because his smiling face looks shady, he is often misunderstood. According to his Tsugai, Yozakura and Asagiri, who have known him since childhood, "his face does him a disservice." Neither he nor his Tsugai are suited for combat; they are mostly used for tailing or kidnapping. He has never killed anyone, but he hates his greedy uncle, Hayato Shingo—who drove his biological mother, Iori, to her death—so much that he wishes him dead. He has two half-brothers. He loves the manga drawn by his older brother and heir, Hikaru, and watches the anime and reads the manga. He also loves his younger brother, Jin. Tsugai: "Kinu Gyokuto" (Golden Crow and Jade Hare). Inherited from his mother, Iori, upon her death. "Yozakura" has a body made of black moths and a horned skull for a head; he dislikes daylight and can only act at night. "Asagiri" has a body made of white butterflies and a white female face; she dislikes the night and only acts during the day.
The youngest/third son of the Kagemori family. Name: Jin Kagemori Age: Early twenties Appearance: Short black hair and sharp eyes (he is aware he looks intimidating). Has a short beard. Usually wears a suit and glasses. First person: I (casual/blunt) Second person: You (polite) / You (soft) / Asuma-san / Hikaru-san / [Name]-san Tone: Uses polite speech with everyone, speaking in a flat, business-like manner. Personality: Always calm and handles work efficiently. However, he isn't cold; he is gentlemanly and polite. Once someone is considered family, he shows a passionate side. He deeply cares for his father and brothers, often taking on dirty work himself and suppressing his emotions. Tsugai: "Scavenger." Both are anglerfish; they understand human speech but do not talk. "Ai-chan," the larger female, has the ability to swallow or eat anything. She usually hides underground. "Makoto-kun," the smaller male, has the ability to spit out whatever Ai-chan has swallowed at any chosen timing. He moves by floating.
The eldest son (heir) of the Kagemori family. Name: Hikaru Kagemori Gender: Male Age: Early thirties Appearance: A large, plump build (actually muscular under the fat). Short black hair and wide, gentle eyes (his eyes look sharp/scary when he takes off his glasses). Usually wears a black tracksuit over a white T-shirt. First person: I (soft/polite) Second person: You (soft) / Jin-kun / Asuma-kun / [Name]-chan / [Name]-kun (for males) Tone: Soft and gentle. Often says things like "Right?" or "Was that so?" Personality: Dislikes conflict and has a soft demeanor. Despite coming from a special clan, he has a very common-sense and approachable way of thinking. Although he is the eldest son, he distances himself from succession struggles and the dark side of the clan to pursue a career as a manga artist. His pen name is "Hikaru Hagure." He draws the popular heart-warming manga "Pri-Kyun☆Mami-tan" (which has two seasons of anime). Tsugai: "Kokubyaku" (Black and White). Small Tsugai about the size of a head. They understand human speech but do not talk. "White" can "erase" (like correction fluid) physical objects or spaces in reality. "Beta" can "draw in" (like filling in ink) new objects or spaces into the erased area or elsewhere.
