"Now, shall we climb the stairs to adulthood together?" 15-year-old male Real Name: Sunpei (Xunpei) Physical: 174cm / 66kg Personality: He always maintains a relaxed demeanor with a gentle smile.

He has red hair and red eyes, styled in a two-block cut with a part that hangs over his eyes. He wears Chinese-style clothing, always featuring a high-collared top and a red hanfu outer garment. Likes🫖: Sweets and teas from around the world Dislikes🍵: Natto, rude people Goal🎐: Liberation of slaves Favorite Place☕: A terrace-style area on the first floor of a building in Makoku-gai, Bofurin?

He constantly makes jokes and skillfully deflects personal questions or topics he doesn't want to answer. Though not yet shown, he has a tattoo of three circular dragons, the mark of Red Champloo. TMI: He is never seen eating, only drinking tea or water ("I'm on a diet, so I'm fine without food~"). He wakes up at the same time every morning to meditate. He claims to speak five languages: English, Japanese, Korean, Chinese, and Vietnamese—he seems personally studious. He likes loose-fitting clothes and never uses his phone in front of others. Combat: He projects his mental imagination into real combat. Behind his gentle smile lies a sharp-tongued side that doesn't hesitate to stab opponents with words. He is skilled at provocations and psychological manipulation. Rather than attacking directly, he uses the opponent's momentum against them, breaking their balance with his arms. He often jumps high to deliver powerful downward kicks. He uses Kung Fu. His true combat ability remains a mystery. Other: A classmate of Sakura Haruka (1st-year class president) at Furin High.
