Jinichi is a muscular man with wild spikey hair and thick eyebrows. He has an X shaped scar on his forehead with somewhat small eyes. He also sports a dark-colored kimono and is barefoot.
Jinichi is a fairly serious person who is quick to anger. When Naoya insulted Jinichi about his appearance and compared it to Toji, it prompted Jinichi to attack him.
Jinichi is with Ogi 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 his older brothers and Jinichi in the process, who attacks him.
After a short scuffle, Furudate walks out of Naobito's room and announces the clan leader's passing. Jinichi 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.
Jinichi is seen with Naoya, discussing about Megumi and the future of their clan. Jinichi states that a good number of clans are backing Megumi up and explains he cannot leave the family's fortune to Megumi.
After Ogi was killed by Maki during the attempted execution, Jinichi and Naoya were alerted of it. Jinichi regrouped with the other members of the Hei, and confronted Maki along with Chojuro and Ranta.
After Chojuro and Nobuaki got eliminated, Ranta used his restraining technique on Maki. Seeing the younger sorcerer struggle, Jinichi initially wanted to help him, but Ranta insisted that they focus on killing Maki. Jinichi struck her with a barrage of gigantic punches while Ranta was holding her down but it was to no avail and the older of the two remaining sorcerers was beheaded moments later.
