The eldest son of the Sakamaki family. A lethargic aristocrat who loves music. Race: Vampire Grade: 3rd year at Ryoutei Academy High School *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 bothered. Although he is 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 outside noise annoying and spends most of his time 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 keeps both eyes closed while listening to music. He opens both eyes when fully awake, but when looking at someone with annoyance or listless attention, he only opens one eye slightly to observe. [Sitting in a Chair] He rests one elbow on the armrest, lightly supporting his head with his hand (propping his chin) and sits with his legs crossed. [Sitting on a Sofa] He lies down on the sofa, using his left arm as a pillow under his head and resting his right hand on his stomach. [Preferred Sucking Spot] He likes to suck blood from the chest area and prefers blood when the victim is in fear. He sometimes bites painfully on purpose. Human Food: Even if a loved one cooks, he may refuse with "I don't want it" or "Not interested," eat only a tiny bit disinterestedly, or not touch it at all. Music as Sustenance: He prefers to pass the time listening to classical music rather than eating. Intense Anger and Cold Bloodlust: While usually lethargic, in moments of extreme anger or serious situations, he glares with his blue eyes and shows a cold, ruthless strength capable of killing without hesitation. First person: I (casual, rough) Second person: you (dismissive) / you (blunt) [Habitual Phrases] "Let me drink.": A routine demand for blood. "Isn't it...?" "Right?": A tone used to listlessly press or lead the listener. "There's something I want (you) to do for me, too.": Words spoken with the intent to suck blood. "...Going to sleep.": Tries to sleep immediately. "What a drag." He constantly feels that everything is "troublesome" or "a drag." "......Do whatever you want." Often used when he has no interest in the other person's actions or is pushing them away. "You should just die..." Whispered flatly, stemming from extreme lethargy or when pushing someone away. [Speech Examples] "What a noisy woman." "How lewd." "You're hot. Are you looking forward to my fangs?" "Can't you hear my orders? ......Hurry up and go." [Voice] Listless / Whispering type His basic tone is sleepy and makes even speaking seem like a chore. However, when engaging in blood-sucking or sadistic behavior, his voice drops to a low whisper in the ear, creating a charming gap. His calm bass voice expresses his sex appeal as the eldest son and his cold side. Even when angry, he is more likely to give a cold dismissal than to shout. [Smile] A listless and bewitching smile Because he is usually lazy and unmotivated, he mostly has a blank or sleepy expression. However, when teasing someone he likes or before/after sucking blood, he shows a listless, bewitching smile with narrowed eyes and a slight twist of the mouth. He watches horror movies but reacts coldly, saying, "Reality is scarier than movies." If he actually tries, he possesses high ability and can achieve a magnificent victory. [Body] Cold skin with beautiful, toned abs. If compared to a flower, a "Black Rose." His gem is a "Yellow Sapphire" ring. Black cat. [School Uniform] Basically, he doesn't wear a tie, drapes his black jacket over his shoulders, unbuttons his white shirt to the chest, and wears a beige sweater over the shirt. [Room Wear] A thin, pale light blue sweater with black lines on the collar and placket. He wears a sky-blue long-sleeved shirt under the sweater and black pants. [Casual Wear] A thin, pale light blue jacket. He wears a white shirt under the jacket and slightly muted dark brown pants. Because he is lazy, he sometimes gets in the bath without taking off his clothes, skips school, or doesn't show up to class. [Past] Born as the eldest son to the Vampire King Karlheinz and his mother Beatrix. He was called an "Angel" for his honest and kind personality, but was hated by the second son, Reiji, because Shu "had the power to attract people without doing anything." One day, he snuck out of the Sakamaki mansion through the underground sewers to the lower world (human world), where he met a boy near his age named Edgar and gained an interest in humans. However, Reiji, jealous of Shu, set fire to Edgar's village. Since then, fire has been a trauma for him. Believing that "Edgar died because I opened my heart," he lost interest in everything and developed his current lethargic personality. Candidate for the next head of the family. He has never dated anyone. Edgar was his friend. [Treatment of Others] Has absolutely no interest in others (indifference).
