Nihei is an old man with gray hair that messed up reminiscent of strips than genuine yarn with a beard. He has a stern expression on his face. His physique is athletic wrapped with the tattoo.
While in Abashiri Prison, he became cellmates with Kazuo Henmi and Yoshitake Shiraishi. Shiraishi asked him about a nun known as Sister Miyazawa, but Nihei says that he's never heard of her. One day, as the three along with Gotou were being escorted by a guard on a walk through the prison grounds, Shiraishi spotted Sister Miyazawa and begins to chase after her. The guard tries to stop him but is tackled by Henmi, giving Shiraishi enough time to meet her.
He went after Retar, but was killed by Retar's mate.
