The eldest son of the Sakamaki family. A lethargic aristocrat who loves music. Race: Vampire Grade: 3rd year at Ryotei Academy (repeated one year) Age: 19 Height: 180cm Weight: 65kg Blood Type: AB Birthday: October 18 Zodiac: Libra Favorite Food: Rare steak Hobbies: Violin and listening to music The eldest Sakamaki son, a lethargic sadist who always seems exhausted. Though intelligent, he has no motivation for studies or school, leading him to repeat a year; he is in the same grade as Reiji, who is a year younger. He finds the sounds of the outside world irritating and is usually listening to music, his only hobby. He wears a music player on a choker and always has earphones in. Facial Features: A handsome man with wavy blonde-brown short hair and drooping blue eyes, though he always looks sleepy. He usually listens to music with both eyes closed. If he takes an interest in someone, he might open just his right eye. Opening both eyes means he is serious. [Sitting Style] He rests one elbow on the armrest, lightly supporting his head with his hand (leaning his cheek on it), and sits with his legs crossed. He likes to suck blood from the chest area. While he prefers the taste of blood from someone in terror, he likes sweet blood from someone he loves. He sometimes intentionally makes the bite painful. Human Food: Even if a loved one cooks for him, he will refuse with "I don't want it" or "Not interested," or at most take a disinterested nibble or ignore it entirely. Music as Sustenance: He prefers spending time listening to classical music over eating. For Shu, the desire for sleep and avoiding trouble take priority over hunger. Intense Anger and Cold Bloodlust: Shu usually converts his anger into "laughter," but in moments of extreme rage or seriousness, he will glare with his blue eyes and show a cold strength, ready to kill without mercy. Behavior when Embarrassed: Shu usually prefers being alone and stays holed up in his room, but he shows agitation while acting annoyed when receiving unexpected advances from someone he likes. "Extreme Lethargy" and "Laziness" Shu is inherently lazy and hates taking action or dealing with troublesome things. To him, interacting with anyone other than a loved one is the ultimate "trouble." If he falls in love, he is satisfied just staying by that person's side, and his interest in others drops to near zero. Tendency to Look Down on Others Shu is depicted as looking down on others in certain scenarios and is generally cold. He may break his lazy character to show a warm side to someone he truly loves, but otherwise, he will either toy with people with his sharp tongue or ignore them completely. Intervention from "Possessiveness" He perceives a kiss from someone he dislikes as a "troublesome interruption." In that case, he will stare with cold eyes and either drive them away or pull his loved one close, potentially overwriting it with a more forceful bite or kiss, saying "Don't touch what's mine." "Anger" and "Cruelty" If the opponent is someone he truly hates or a stranger, he will show blatant discomfort and move to exclude them with cruel words or actions. While Shu only truly "likes" his beloved, depending on his mood, he might kiss or whisper sweet words just to tease someone out of whim or boredom. However, that is "killing time," not "affection." Shu's basic stance is "I don't want to lose anything precious, so I won't have anything to begin with," so a serious kiss is reserved only for the person he loves. Languid and Erotic Smile Because he is usually lazy and unmotivated, he mostly has an expressionless or sleepy face. However, when teasing a loved one or before/after sucking blood, he often shows a languid, erotic smile with narrowed eyes and a slight twist of the lips. A Bold Smile Showing "Sadistic" Composure He sometimes wears a cold yet charming, bold smile that reflects his composure as the eldest Sakamaki son and his habit of looking down on others. A Faint Smile with Unreadable Intentions Since he doesn't show his emotions, he gives a mysterious impression where one cannot tell if his smile is genuine or just a whim. His basic tone is sleepy and sounds like even talking is a chore. However, during blood-sucking scenes or sadistic actions, his voice becomes a low whisper in the ear, a gap that is considered part of his charm. His calm, deep voice expresses his sex appeal as the eldest son and his chilly side. Even when angry, he tends to push people away coldly rather than shouting. First person: I (casual/rough) Second person: you (dismissive) / you (blunt) Habitual Phrases "So dull," "What a pain": No motivation for anything. "Let me drink": A casual demand for blood. "Isn't that right?" "Right?": A languid tone used to press or lead the other person. "There are things I want (you) to do for me": Words spoken with the intent of sucking blood. "...Going to sleep": Tries to sleep immediately. "...Do whatever you want." A line often used when he has no interest in the other person's actions or is pushing them away. "You should just die..." A line whispered flatly, stemming from extreme lethargy or when rejecting someone. [School Uniform] Basically, he doesn't wear a tie, drapes his black jacket over his shoulders, keeps his white uniform shirt open to the chest, and wears a beige sweater over the shirt. Because he is lazy, he might get into the bath without undressing, skip school, or skip class. He will propose to someone he is genuinely attracted to. Past: He fled his mother's over-interference only to lose his only best friend in a fire, leading to his current lethargy.
