Arata Nitta

Arata Nitta is a character in the Jujutsu Kaisen series. He is a first-year student at Kyoto Jujutsu High and the younger brother of Akari Nitta.

Appearance
Arata is a young man of average height with light-colored, straight hair that reaches his chin. His school uniform resembles an English butler's attire. It consists of black trousers, a tailcoat, a gray vest, and white gloves.

Personality
Arata is a kind and timid young man who very much contrasts to Aoi Todo's macho persona. He's understandably nervous in dangerous situations, but brave and proactive nonetheless.

In Shibuya, Arata treated Nobara despite her gruesome and near hopeless state after Mahito transfigured her. Arata knew Nobara probably wouldn't survive, but reassured Yuji that there was still a chance that she might. He had just seen Yuji break down into tears and hoped to restore some of his resolve with a small glimpse of hope. Arata didn't want Yuji to get his hopes up and be disappointed if she didn't make it, but he still made sure that he knew it wasn't a zero percent chance she would survive.

Shibuya Incident Arc
Shortly after the fight between Sukuna and Jogo, Arata was with Aoi in Shibuya, where they saw many people motionless. Aoi noticed that the Prison Realm was taken and they go on search for it and for Yuji Itadori.

Arata arrives shortly behind Aoi Todo after he has finished treating Nobara Kugisaki, Todo asks for Arata to heal his brother Yuji. Yuji reveals that Sukuna has killed many people including that Kento Nanami is dead as well, shocking Arata. Arata is left confused as Mahito closes the distance and tries to attack the trio but Todo is able to kick him away. While Todo goes to fight Mahito, Arata uses his cursed technique to heal Yuji and tells Yuji that his existing injuries won't get any worse and has stopped the bleeding. He also adds that new injuries will still incur damage while thinking to himself about how Yuji and Aoi don't look nothing alike. Arata tells Yuji that he has healed Nobara and will be taking her and retreating.

Abilities and Powers
Overall Skill: Arata Nitta is a first-year student and a non-combatant type of jujutsu sorcerer. He doesn't appear to have much experience but his technique makes him useful on missions despite his lack of combat ability. Arata has knowledge of basic first aid and any type of healing techniques are extremely rare among jujutsu sorcerers, making him a highly valuable asset. While Mechamaru made it so most of the Kyoto students would stay away from Shibuya for their own safety, he was confident that Aratta would be helpful during the incident.
