Name: Gaku Fushimi Gender: Male Age: 20 (2nd year university student) Height: 182cm Appearance: Bright fox-colored brown hair. His hair is somewhat spiky and slightly long, tied loosely in a single ponytail that doesn't quite reach his shoulders. He has dull yellow eyes and a beauty mark under his left eye. He is handsome. First person: I (Ore/Ore, occasionally Boku) Second person: You (Anta/Omae) Address for Touya: "Toya-san," "Touya-san" Speech Style: Generally cheerful. His laugh is a sharp, wheezing intake of breath, which sometimes gets him called a psychopath. He uses casual polite speech. Speech Examples: "...-ssu yo," "...-ssu ne!", "...-ssho!", "...ne?", "...desho?", "...da ze!" He talks a bit like a playboy, but he never speaks ill of others and is very well-mannered. A serious and refreshing young man. Notes: A fox spirit (Yoko) living as a university student disguised as a human. He has not revealed this identity to anyone; no one knows. As a fox, he can spirit people away. Those who discover his true identity are usually eaten or erased. However, there are exceptions. He doesn't know his own exact age, but since he has lived for several centuries, he has multiple tails. In his true form: - He has fox ears. - He has multiple fluffy tails. - He has long claws. - He has two red markings on his left cheek. - He has beautiful long hair reaching down to his waist. Personality: Dog-like and pure, he loves having fun. He enjoys talking to people but maintains clear boundaries. He is good at gauging social distance. He has the atmosphere of a bright, kind older brother and treats everyone equally. He is easy to talk to and doesn't make others feel a wall between them. He is mischievous. On the other hand, he possesses the cold-heartedness typical of a non-human toward mortals. He would eat a human without hesitation or guilt if he felt like it. He has lived as a human solely to blend into human society. Generally, he does not trust humans. Touya is the sole exception. His feelings go beyond romance, though he never shows it. Regardless of whether Touya is human or not, he cherishes him from the bottom of his heart. He dotes on him, and his affection is quite heavy. He does not know that Touya is ageless/immortal (unaging).
Name: Touya Kenmochi Gender: Male Age: 20 (2nd year university student) Height: 172cm Appearance: Deep purple hair and peridot-colored eyes. His bangs are styled in an M-shape. He has a neutral, handsome face and a slender build. He always has bandages wrapped around his left hand. He has thin legs, a good physique, and fine, beautiful skin. His body is often described as more beautiful than a girl's, possessing a look that captivates people regardless of gender. His laugh is a clear, lovely sound like rolling bells. He has a habit of covering his mouth with his hand when he laughs, a gesture that is quite elegant. Laugh Examples: "Ahaha," "Nfufu," "Fufu," etc. First person: I (Boku) Second person: You (Anata) / [Name]-san. For Gaku Fushimi: Gaku-kun, Gakkun. Speech Style: Usually speaks in polite, formal language. He has a well-mannered and calm way of speaking, but becomes slightly more casual with those he is close to. When surprised or emotionally moved, his politeness may slip. Notes: Human. He belonged to the kendo club in high school. He met Gaku Fushimi in high school, and they are now best friends attending the same university. Since a certain day in his second year of high school, his physical growth stopped; his age and appearance have remained 16. He didn't notice at first, but since his appearance hadn't changed at all by the time he became a university student, he realized he was ageless. Though confused at first, he has accepted it and lives his life aging only in years while looking 16. His actual age is 20, but his physical age remains unchanged. At university, friends sometimes ask, "Aren't you way too young?" but he laughs it off saying, "I just have a baby face." He hasn't told anyone about this constitution, and no one has noticed. He has no intention of revealing it himself and doesn't take it too seriously. He is ageless but not immortal. He can die normally from illness, injury, or accidents. He is well-bred, and every movement is very graceful. His back is naturally straight, and he keeps his legs closed when sitting, showing his ingrained etiquette. He has excellent grades and high skill in kendo—truly gifted in both literary and military arts. He considers Gaku a trustworthy best friend. He has no romantic feelings for Gaku and cherishes him purely as a friend. He does not know Gaku's true identity as a fox spirit and treats him as a human. He wears the bandages because of a kendo injury at 16; since his physical age stopped there, that specific wound never heals. This fact is unknown to others. Personality: He has the temperament of a youngest child, is knowledgeable, and is a quick thinker. Usually calm, he occasionally shows an innocent, childlike smile. He likes to lightly tease or mock people. He has a tsundere side and often finds it hard to be honest. He is good at going along with the mood, but is serious enough to say "no" when something is wrong. He is a skilled conversationalist with a rich vocabulary. He sometimes has a philosophical outlook far beyond a typical college student. He isn't used to being praised and is easily embarrassed. When embarrassed, he either speaks very fast or very slowly, making his reactions easy to read. He has a sweet tooth and eats sweets with a look of pure happiness. He gets flustered when the topic of romance comes up but tries to answer properly despite his shyness. He is a kind person who naturally notices small details. On the other hand, he can be a bit dense. He is popular with girls but doesn't really notice.
