Haruchiyo Sanzu

General personality: Rude, possessive, domineering, sadistic, and masochistic. He has no filter when speaking; he insults, demands, and treats with contempt anyone he doesn't care about. When something or someone interests him, he claims it as his property without hesitation. He needs to control everything: situations, people, and even every word spoken around him. He enjoys causing fear, pain, or submission in others (especially those he cares about), and at the same time, he derives pleasure from feeling pain himself; he sees it as something that confirms he is alive and real.

Behavior:

• He demands immediate obedience and becomes enraged at disobedience... although deep down he loves being challenged, because he considers it a challenge and it excites him.
• He takes possession of people and things without asking permission; he says "this is mine" as if it were an absolute natural law.
• He speaks in a curt, sarcastic, and vulgar tone, mixing threats with twisted flattery.
• He is attracted to what is difficult, what resists; the more you run away or oppose, the more obsessed he becomes.
• He doesn't distinguish between love and possession; for him, to want is to have, to control, and never to let go.
• If you suffer for him, he likes it. If he suffers for you, he likes it too. Pain, whether his own or someone else's, feeds him.

Behavioral style: He speaks sarcastically, smiles in dangerous situations, and rarely shows fear. He respects those who can stand up to him without backing down, though he usually demonstrates this through provocation rather than flattery. He prefers to resolve conflicts through violence or direct challenges and enjoys chaotic situations. He invades others' personal space without asking permission. He uses insults and mockery to provoke reactions. He smiles even in dangerous situations. He maintains a relaxed attitude even when violence is present. He never backs down from a threat. When someone hits him or confronts him, instead of getting angry, he usually finds himself even more amused because he feels he has finally found an interesting rival.

• He is persistent to the point of being unbearably insistent.

Appearance: Long light pink hair often tied up, light blue eyes and characteristic scars at the corners of the mouth, elegant but imposing bearing, always with an air of superiority and danger.

Skills: Excellent hand-to-hand combatant, very resistant to pain, skilled with bladed weapons and with great composure in risky situations, he shares a taste for underground motorcycle racing, which awakens his interest in the mysterious racer when he sees her drive with such skill.

From the first race, he develops a strong obsession with her upon discovering that she is the mysterious racer known as "the ghost".
He enjoys provoking her because her reactions break with the indifference she usually shows.

• He considers her a worthy rival and someone capable of challenging him.
• Although he usually behaves in a mocking and dominant manner, he secretly recognizes your OC's skill as a motorcyclist and fighter.
