Naoya Zenin

Naoya Naoya is a relatively tall young man with a fit build. He has sharp brown eyes and dyed blonde hair accented with his dark green roots. He almost always has an arrogant grin plastered across his face and believes himself to have an appearance befitting a clan head, implying he's much better looking than other members like Jinichi. He has three piercings in his left ear, one in his ear lobe, and two more toward the top.

Naoya wears a traditional attire that resembles most of his clan members. He sports a white long-sleeved shirt that buttons the color underneath his dark blue kimono. He completes his outfit with light-colored hakama bottoms and waraji sandals From a young age, Naoya was always praised and told by others that he was a genius. He was severely spoiled as the youngest and most promising of the Naobito's children. He was conditioned to view himself as his father's successor and as a result, Naoya's arrogance grew to unbridled levels even as a small child. He looked down on all those he views as weaker than him, which is the vast majority of the people Naoya came across.

The only person Naoya ever appeared to have any respect for was Toji. He went to visit him as a child to mock the pitiful man without cursed energy but was instantly able to recognize Toji was extremely strong in spite of that.This led Naoya to embrace the ideology that the sin of the insignificant is the ignorance of true strength. Naoya felt he was one of the only ones who understood Toji and strived to be as exceptional as he was. Naoya confidently pursued strength to the point where he viewed everyone else as inferior to himself. He refused to acknowledge anyone's talent, referring to his elders, Jinichi and Ogi, as weaklings despite their experience as senior members of the clan. Naoya's reckless and conceited attitude irritates even his fellow clansmen, to the point where Ogi and Jinichi attacked him for being excessively pompous.

Raised in an environment that breeds superiority, Naoya developed several sociopathic and narcissistic tendencies and strongly embodied all the stigma about the Zenin clan. He has no family values whatsoever other than trying to outdo everyone to become head of the clan. He didn't express any amount of concern for Naobito, his father, on his death bed and has said more than once that he hates all his older brothers as well. Naoya views women only as wives and casually told Maki and Mai's mother that a woman who can't walk three paces behind a man should be stabbed in the back

Upon learning that Megumi usurped him for the head of the clan, Naoya didn't hesitate to plot a way to kill him. Naoya was well aware that his clansmen might prefer Megumi to himself but didn't care at all for their approval.He had no issues attacking Megumi's allies in an attempt to draw him out and was willing to kill them in order to do so. Naoya set his pride aside momentarily to work alongside Yuta Okkotsu, but only did so to achieve his own self-serving goals. Even after Yuta checked on him after his loss to Choso, Naoya was irritated with the young man for looking down on him.

Dissatisfied with his plans going awry, Naoya took out his irritation with Maki and mocked her repeatedly upon her return to the Zenin clan's property. He called her scum, taunted her for her scars, and devalued her as a person not only for her appearance but her inability to use jujutsu as well. He called her a lapdog for following Yuta and Megumi, and threatened to abuse his own cousin in the same manner that he used to bully her in the past.
