Ogi Zenin is a character in the Jujutsu Kaisen series. He is the brother of Naobito Zenin and father of Maki and Mai Zenin.

Appearance
Ogi is a tall man with black sclerae, no visible pupils, and long, black hair slicked back into a high ponytail. Ogi's attire consist of a white shitagi, a white kosode and dark hakama with white socks.

Personality
Ogi is a serious man who follows the ideals of the Zenin Family. He dislikes Naoya and immediately attacked him for insulting him around the time of Naobito's death. Even so, he proposed killing his own children and Megumi Fushiguro in order to retain the Zenin Family fortune, revealing a ruthless side. He believes he couldn't become head of the clan because his children are worthless without any talent for jujutsu.

Itadori's Extermination Arc
Ogi is with Jinichi Zenin in one of the rooms of the Zenin household when Naoya Zenin walks in. Naoya says that he'll become the next clan leader while insulting Ogi and Jinichi in the process, who attacks him. After a short scuffle, Furudate walks in and announces the clan leader, Naobito Zenin passing. Ogi listens as Furudate reads Naobito's will, revealing that, in the case of Satoru Gojo's disappearance, Megumi Fushiguro is to become the next clan leader.

Culling Game Arc
Ogi was waiting in the Zenin family cursed warehouse as Maki arrived. He reveals there are no cursed tool's as he stands next to an injured Mai. Ogi decided that he will execute his daughters and Megumi, to strengthen the trust between him and the higher-ups. Ogi uses Falling Blossom Emotion to fight Maki. Maki manages to brake his blade in the initial exchange but when she whipped around, he turned before her and cut her down, breaking her Dragon-Bone sword. He then slashes Maki, claiming the reason he couldn't became the head of the clan, was because his children are worthless.

Abilities and Powers
Overall Skill: Ogi is a special grade 1 sorcerer that has yet to showcase his full power.

Tactical Intellect: It was Ogi's idea to frame Megumi Fushoguro, Maki, and Mai Zenin for trying to unseal Gojo Satoru, showing a devious and calculating mind. He also predicted Maki's arrival in the Zenin residence, emptying the weapons cache ahead of time. His caution also led him to think ahead and leave Maki incapacitated to use as a hostage in case his duel with Maki went wrong.

Master Swordsman: Ogi wields a katana and was skilled enough to attack quickly with it, nearly slicing Naoya. He is also able to overpower Maki in a sword duel.
