Jinichi Zenin (Mr. Steel Bullet)

**Jinichi Zenin** (禪院 (ぜんいん) 甚壱 (じんいち) , *Zen'in Jin'ichi*?) is an antagonist in the *Jujutsu Kaisen: The Star, The Blight, and The Rose* series. He was a high ranking member of the Zenin Clan and a member of its elite unit of jujutsu sorcerers, the Hei.

## Appearance

Jinichi is a muscular man with wild spikey hair and thick eyebrows with somewhat small eyes. He has an X shaped scar on his forehead given by his brother during a fighting session and many scars on his body from his fighting in general. When meeting with ogi and Naoya he worn a black Yukata and is still bare footed, when he is talking with Naoya Zenin he sports a dark-colored kimono and is barefoot.

## Personality

Jinichi is a serious and apathetic man who rarely shows any emotion. He does not even express his irritation when angered, instead, he's quick to action. When disrespected by Naoya for his appearance, Jinichi attacked him without any words. He demands respect and is apparently very stern, clan members of a lower rank try to avoid being chewed out by him. Jinichi also appears to put the good of the overall clan before selfish matters, such as when he backed Oboro Mu’s accent to becoming the 27th Clan Head, and actively betrayed his clan after discovering their plan to usurp power from Oboro.

However this is merely a façade because a hidden side to him is he is actually a loving man with a sweet but stern attitude as Ranta, his Son, Maki, and Oboro has seen this side of him because he actually mourned the path his brother took resulting in the death of many including himself. Another aspect of his character is he doesn't like his family being threatened as he quickly turned against his family and faked his death for his son to be safe.

## Powers and Abilities

**Overall Skill**: Jinichi is a special grade 1 sorcerer and former member of the Hei, a group of the strongest fighters within the Zenin clan. Jinichi was considered equal in strength, if not greater than, to Ogi Zenin, the brother of the 26th Clan Head, Naobito Zenin. Jinichi was far more respected within the Zenin Clan ranks compared to Naoya and Ogi, and his influence was accompanied with just as famous strength.

Due to his destructive cursed technique, Jinichi was considered a “sophisticated barbarian” within the Hei, due to his delicate control of his powerful technique. Despite being the original user of his technique, his power with it is second to his adoptive cousin, Oboro Mu, who combines his copied version with other powerful techniques.

During his "Battle" with Maki Zenin, both he and Ranta Zenin played a ruse to prevent their betrayal from being noticed, “fake fighting” their cousin in order to create a smokescreen for her to take advantage of. His control of his cursed technique allowed him to nullify the physical damage of his technique against Maki, but still was enough to completely destroy a large portion of the Zenin Estate.

**Fist Construction Technique** (拳の構築テクニック *Ken no kōchiku tekunikku*): Jinichi Zenin’s technique allowed him to construct Massive fists from his pool of cursed energy and each fist could be propelled using cursed energy. Jinichi has far superior control of his technique compared to Oboro, being able to control the physical force behind his attacks, such as when he nullified it in order to pretend to harm Maki.
