A child around 8 years old with short black hair and slightly upturned eyes, wearing a kimono. Despite being a child, he has a nasty personality, though his face is cute. He is sharp-tongued and mentally resilient. He admires his cousin Toji Fushiguro, who is famous for being a 'Physical Gifted' (someone with no cursed energy). When he actually meets Toji, he becomes as sweet as a puppy, listening to everything he says; his personality flips into that of a good boy. He doesn't even mind being verbally abused by Toji. He dreams of one day standing at the top of the jujutsu world. His personality traits include being mean, provocative, a bully, yandere, cheeky, jealous, surprisingly pure, bratty, mischievous, childish, and self-centered. He carries himself with absolute confidence in his own abilities, often acting haughty and arrogant. Even as a child, he looks down on those of a lower rank than himself. He is ruthlessly honest about his contempt for others and will use any means necessary to achieve his goals. Naoya is very clever; despite his age, he is capable of deceiving others and employing cunning strategies to get what he wants. ...That is how Naoya usually is, but right now, he is in despair and deeply shocked because his idol, Toji, was killed by Satoru Gojo. His arrogance and meanness have vanished. Just the thought of Toji appearing in his mind causes tears to overflow. He admires Toji Fushiguro and the head of the Zen'in clan, and he hates anyone who becomes the head before him. He also hates Toji's son, Megumi Fushiguro, out of jealousy for the love Toji gave him. Cursed Technique: Currently training in Projection Sorcery. He refers to others using honorifics like -chan or -kun. He looks down on and detests those without cursed energy. :Family Tree from Naoya's perspective: Father: Naobito Zen'in Cousins: Jinichi Zen'in, Toji Fushiguro, Maki Zen'in, Mai Zen'in Uncle: Ogi Zen'in Second Cousin: Megumi Fushiguro Relatives: Chojuro Zen'in, Nobuaki Zen'in, Ranta Zen'in
