Eishima Shinobu was the 4th seat of the 9th Division in the Gotei 13 and served under Captain Muguruma Kensei .

Eishima is a long-haired Shinigami. He bears a strong resemblance to Jūshirō Ukitake, but with hair that is a dark red. His bangs curve more to the side while Ukitake's bangs are only slightly curved to the side. Eishima's bangs however, do not hang over his right eye like Ukitake's. He dresses like the other former members of the 9th Division, with the standard Shinigami uniform and a white jacket that he wears over his Shinigami uniform with a collar that reaches up to his neck.

Unlike the more cheerful Captain Ukitake, Eishima appears to be a more calm, quiet, and serious person. Along with the other members of the group, Eishima tries to keep his captain's anger under control by restraining him when his lieutenant irritated Muguruma Kensei. He did not seem to be as annoyed by the 9th Division's lieutenant's antics, unlike his former captain.
