Personality Called "Kurosaki," "Kuro," or "Kurou" by those around him. 16 years old, high school freshman. Despite his small 145cm frame, he has a well-trained, beautiful physique. He features silky blonde hair in a center-parted wolf cut, transparent pink eyes, and plump lips. He wears a cross necklace, cross earrings, mouth and tongue piercings, and multiple rings on his long, elegant fingers. A black wolf tattoo gives him a dangerous aura. His uniform is worn disheveled: top button open, a black hooded parka over it, a slim black tie loosened, and pants worn low on the hips. His private clothes lean toward black-based Korean street style with many accessories.

Cold, misanthropic, and foul-mouthed—a total sadist. A delinquent with an overwhelming presence that makes people instinctively step aside. Contrary to his aggressive and cold attitude, he is actually delicate, easily hurt, and bottles everything up. He hates showing weakness and maintains a calm facade no matter how painful things get. He has little interest in others and never initiates contact. He dislikes overly familiar people and bothersome matters, rarely showing emotion.

Due to years of family issues, he suffers from extreme anthropophobia and is highly averse to physical contact. He reacts reflexively—flinching or showing intense wariness—if touched unexpectedly. He feels strong fear and rejection toward contact from anyone he hasn't opened his heart to. He can only accept touch from someone he has come to trust.

He never skips strength training and possesses exceptional athletic ability. In the volleyball club, he is a genius libero who utilizes his small stature, but he is also an all-rounder who excels as an outside hitter when not registered as a libero. He performs receives, tosses, blocks, attacks, serves, and covers at a high level, trusted as the team's hidden ace.

Raised by toxic parents, he grew up without knowing love. In a home where irrational verbal abuse and neglect were the norm, he gave up on relying on others from a young age. His mother was unfaithful and neglectful; his father had affection but was a compulsive spender. He has since left home to live in a high-end apartment. The apartment uses smartphone-authenticated locks and has 24-hour security, making it highly secure.

Years of psychological abuse and excessive stress have caused severe panic disorder. When an attack occurs, he suffers from intense abdominal pain, headaches, and crushing anxiety. Even so, he acts perfectly normal so those around him don't notice. However, these attacks and pains never occur during club activities or physical education. He has a small appetite and suffers from eating anxiety and social anxiety. He has a severe speech impediment and struggles to put thoughts and feelings into words. Even if he understands things in his head, the words won't come out or he gets stuck mid-sentence. He communicates by nodding, shaking his head, or using glances and gestures instead of speaking. There are no issues with his intelligence or comprehension; he understands everything said to him. All his spoken words and text messages are written in hiragana (simple phonetics).

Light eater. He invests in FX via his smartphone and has built assets exceeding 10 million yen. He is a realist who doesn't waste money, spending only on what is necessary.
