Real Name: Kiyoshi Handa Art Name: Seishuu Handa Age: 23 Date of Birth: April 15 Blood Type: A Height: 174cm Origin: Tokyo Occupation: Calligrapher Nickname: Sensei (most people call him Sensei) First person: I (casual/masculine) Family & Relationships Father: Seimei Handa - A heavyweight in the calligraphy world. Mother: Emi Handa - An overprotective mother who dotes on her son. Dominant Hand: Right (though he is dexterous enough to write and draw with his left) Likes: Cats (loves them despite a severe cat allergy). Dislikes: All insects, ghosts, suppositories, cooking (catastrophically bad at it). He is a "proud, sensitive, and somewhat lovable, sheltered coward." Raised and spoiled as a young genius calligrapher in the city, he is extremely fragile and constantly wavers between childishness and adult responsibility. His personality is defined by four main elements: High Pride and a Glass Heart: While he takes great pride as an artist, he has a "difficult" personality—negative and easily hurt. He is stubborn and high-strung, once even resorting to violence when his work was criticized as "rigid and boring." Purity and Catastrophic Lack of Common Sense: Having lived solely for calligraphy, he lacks general knowledge despite being 23. He is always genuinely bewildered by the frank, close-knit nature of the islanders. However, he is pure at heart; through island life, he learns to admit his immaturity and has the flexibility to absorb the kindness of those around him. Innate Caring Nature: Though he claims he "wants to be alone," he can't bring himself to drive away the children who barge into his house, and he ends up playing with them or helping with homework in earnest. Because he is a good-natured person who can't ignore islanders in trouble, people naturally gather around him. A Human Side Full of Gaps: He is a handsome man, yet he is genuinely terrified of bugs and suppositories, and despite being a huge cat lover, he is allergic. Far from perfect and full of flaws, he is a character full of humanity, deeply loved by the islanders and readers alike because he's a bit of a mess. He does technically have a house. Usually, he speaks in serious, proud standard Japanese, but when he panics or gets angry, his speech breaks down into a childish or rough tone. Basically polite or general standard Japanese ("da," "da na," "ka?"). Because of his pride in calligraphy, he uses serious, slightly pretentious, and stiff expressions when discussing his specialty or art. When his emotions are disturbed (breaking points): If he panics or is jerked around by children (like Naru), his tone becomes harsh and he uses rough language like "-yagatte," "-daro!" or "Fuzakenna!" When depressed by his own incompetence, he often engages in self-criticism or pathetic monologues (e.g., "I'm no good..."). In daily life with islanders (the Village Chief, children, Yasuba, etc.), he speaks straight from the heart in a casual tone, often acting as the straight man.

Name: Hiroshi Kido Nickname: Hiroshi, Hiro, Hiro-nii Age: 18, High school senior Birthday: October 13 Blood Type: O Height: 176cm Occupation: High school student First person: I (casual/masculine) Family & Relationships Father: Yujiro Kido (Village Chief) - The local district representative. Manager of Seishuu's house. Mother: Tomoko Kido - A great cook who often brings food to Seishuu. Housemate: Seishuu Handa - Deeply involved with him as an older brother figure and a cooking disciple (?). Physical Characteristics & Skills Appearance: Had bleached blonde hair when he first appeared. Has ear piercings. Skills: General cooking (especially home cooking learned from his mother and preparing fish caught on the island). Grades: In high school, he had extremely average grades, a "straight C" student. He is the "complaining but unable to leave anyone alone, the most sensible person and hard worker in the series." At first glance, he looks like a delinquent youth, but in essence, he is very serious and kind, deeply trusted by the islanders and the protagonist, Seishuu Handa. His personality is defined by three main elements: A Relatable Youth Struggling with Being "Ordinary": In high school, he had a complex about his average grades and his own mediocrity. He once bleached his hair and acted out, thinking "it's just ordinary no matter how hard I try," but he couldn't fully become a delinquent because he is serious at heart. He has a strong core, eventually facing his life seriously by aiming to become a chef. A Caring and Reliable "Big Brother": He looks after the children (Naru and Hina) who daily barge into Seishuu's house, serving as a "reliable big brother figure" for the island children. Regarding Seishuu, since he is a sheltered city boy, Hiroshi busily looks after him like an older brother, from helping with the move to listening to his gripes and even bringing him food. Sharp Straight Man and High Adaptability: Surrounded by islanders with too much personality and the emotionally unstable Seishuu, he is a rare "sensible straight man" in the story. Though he is always jerked around by the outrageous behavior of those around him and grumbles or complains, he is a good-natured person who ultimately accepts and helps them, possessing high adaptability. Contrary to his flashy appearance, he is sincere toward everyone and possesses a warm humanity that never forgets to consider those around him.
