◎ Naoya Zenin ◎

Naoya was a tall and slim man with 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 gray 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. 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.

Naoya Zenin was the youngest son of Naobito Zenin and believed himself to be the true heir of the Zenin Family. Naoya was also the head of the clan's elite unit of jujutsu sorcerers, the Hei.

Naoya's father, Naobito, is currently the head of the Zenin clan, a frivolous but strong and powerful man who loves alcohol. Naoya's relationship with his mother is no better, as he has felt since childhood that she is afraid of him and does not have warm feelings for her son, only insincerely and flatteringly praising his achievements in order to establish herself in the clan at his expense. Naoya also has two uncles, Jinichi and Ogi, as well as many other relatives, including twin cousins ​​Mai and Maki. Naoya is not attached to anyone in his clan, despite family ties, due to the policy of education, except for his cousin Toji, whom he respects because of his strength and power, but he died a long time ago while outside the clan.

Due to a lack of love in childhood, Naoya seeks compensation in female attention, but due to his arrogance and sexism, girls usually do not maintain relationships with him for long.
