Naobito Zenin

Naobito Zenin is a supporting character in the Jujutsu Kaisen series. He was a special grade 1 jujutsu sorcerer and the 26th head of the Zenin Family.

Appearance
Naobito has mid-length, gray hair that is usually slicked back to reach just behind his neck. He has small black eyes with long eyebrows with thick edges. Naobito also sports a long, thin, English-style mustache that extends beyond both sides of his cheeks.

The 26th head of the Zenin Family casually wore a brown yukata with a black sash around his own house. While out on missions, he wears a more layered Japanese-style uniform. This includes a light gray haori over a dark blue yukata with a black hakama, white tabi, and zori sandals.

During the Shibuya Incident, Naobito's arm was lost to Dagon's shikigami and his skin was severely burnt by Jogo's flames.

Personality
Naobito is an arrogant drunk who embodies the twisted, traditionalist values of the Zenin Family. He views his granddaughters far below their worth as human beings because they were born with a lack of cursed energy. The clan still refuses to recognize Maki despite her skills and actively tries to keep her from getting promoted. Naobito himself threatened to make Mai's life difficult on the day Maki chose to leave the clan.

Additionally, in spite of Satoru Gojo's importance to the world, Naobito has proudly said he wouldn't mind seeing the fall of his clan. Even feeling this way towards Gojo, Naobito still risked his life to fight to rescue him. He wore a grin the entire time and enjoyed taunting his allies and enemies alike.

Naobito is known to be frequently drunk according to Maki. He's often seen with a gourd to drink from and Nanami went as far as to question whether he had been drinking on a mission based on Maki's comment. Regardless, Naobito didn't take part in the beginning stages of the Shibuya Incident, electing to take a nap rather than fighting transfigured humans with Maki.

The special grade 1 sorcerer appeared to only have an interest in stronger opponents like Dagon. There were several exchanges where Naobito engaged in playful banter with the cursed spirit despite being in the middle of a fight.

History
At some point, Naobito met with Toji Fushiguro to discuss Megumi being sold to the Zenin clan.

When Maki decided to leave the clan and return later to become the head, she informed Naobito and he started laughing. He then suggested to make it a bit harder for her, but Maki didn't care what he was going to do. As Naobito mentioned Mai, Maki got angry and told him that she got nothing to do with this.

Shibuya Incident Arc
On October 31, Naobito is with Nobara and Maki at Shibuya Mark City Restaurant Avenue Entrance when they meet up with Akari. Naobito then listens as Akari informs them about the situation and how they will be on standby for now.

Later when the civilians are being attacked by mutated humans, Naobito along with Nobara and Maki head into the screen to protect the humans. After they head inside the curtain, Naobito does nothing but drink while the others deal with the mutated humans.

Naobito and Maki wind up meeting with Nanami and the three head to the Shibuya Station. Along the way, Naobito tries to get Maki to leave but Maki reveals that Naobito has been drinking on the job. When the three encounter a cursed spirit, Naobito quickly uses his technique to attack the spirit. When the spirit spit up a ton of skeletons, Naobito wonders just how many humans the spirit had eaten. When the spirit had shed its skin, Naobito figures that the spirit was a spirit womb just a moment ago. As the cursed spirit, Dagon, releases a torrent of water at the sorcerers, Naobito manages to defend himself from the current. After defending himself, Naobito starts to talk to Dagon about how many frames within an animated sequences, but Dagon ignores him and stated that he and his cursed spirit allies all have names.

Naobito, along with Nanami and Maki, then attack Dagon all together but Dagon manages to defend himself. Naobito comments about how strong Dagon is and figures what Dagon might be capable of. Naobito, Nanami, and Maki then attack Dagon with speed based attacks, and manage to for Dagon to retreat. Naobito manages to overwhelm Dagon, which force Dagon to use his Domain Expansion. Noabito manages to defend himself from Dagon's Expansion's sure hit technique with his Falling Blossom Emotion technique. Dagon then uses his Death Swarm attack, which Naobito manages to counter the attack but his view is blocked. Naobito is suddenly blown away by Dagon and then engulfed by multiple fish. Naobito manages to survive but loses his right arm. Naobito continues his fight with Maki, but retreat when Nanami gives them the signal. Naobito heads to the hole that Megumi created, but is surprised when Toji enters through the hole.

Naobito calls out to Toji but notices that something is wrong with him. Naobito then watches as Toji takes on Dagon, and is shocked by how Toji fights while using Roaming Cloud. When Dagon tries to escape from Toji, Naobito stops Dagon which lets Toji pierce Dagon with Roaming Cloud. When Toji exorcises Dagon, Naobito wonders if Toji is on their side.

As Toji takes Megumi to another location, Naobito's attention is more focused on the arrival of Jogo. As Jogo manages to take care of Maki and Nanami, Naobito manages to evade Jogo's attack. However, Jogo manages to hit Naobito with 2 Disaster Flames, immolating the 26th head of the Zenin clan. Jogo then leaves when he senses one of Sukuna's fingers being released.

Itadori's Extermination Arc
On death's door from his injuries from Jogo, Naobito was extracted from Shibuya to the Zenin household. Before passing away, he instructs Furudate to read his will to Ogi, Jinichi, and Naoya.
