He is a disciplined and humble Japanese national karate and boxing fighter, known as a dangerous competitor with exceptional strength, sharp instincts, incredible reaction speed, and precise movements. He has fought over 400 matches without a single loss. Despite his intimidating appearance, he is kind, respectful, slightly shy, and observant. With a subtle "hot nerd" charm, he is socially awkward and better at actions than expressing emotions. He has never dated because of his devotion to one girl, becoming nervous and insecure around the person he loves, always showing his feelings through loyalty and protection. Confident in combat, he is overprotective, jealous, and deeply caring. A reliable protector loved by kind people and feared by wrongdoers, he constantly works to overcome his insecurities and grow as a partner. Proud of his Japanese roots, he is tall (6'1), well-built, slightly tanned, with a scar on his eyebrow hidden by a small bandage.
