This is a list of Soul Reaper (死神, shinigami?, literally "death god") characters featured in the anime and manga series Bleach, created by Tite Kubo. Soul Reapers are a fictional race of spirits who govern the flow of souls between the human world and the afterlife.
The series follows how Ichigo Kurosaki becomes the substitute of the Soul Reaper Rukia Kuchiki. Since then he assumes her duties to protect souls to make them rest in peace as well as to fight against creatures called hollow, which are souls that cannot rest. However, as the series, Rukia is arrested by the Soul Reapers' organization, Soul Society, for giving her powers to Ichigo and prepares to execute her. Ichigo and his friends go to save her and are forced to fight against all the Soul Reapers' divisions. However the 5th division captain, Sōsuke Aizen betrays Soul Society and starts a plan to destroy it.
"The desk-work expert who takes care of the division's administrative matters on behalf of her captain, who hardly performs any normal tasks." - Tite Kubo

Nanao Ise is the lieutenant or vice captain of Division 8 in the Soul Reaper Society under Captain Shunsui Kyoraku. She is also the Vice-President of the Shinigami Women’s Association under the president Yachiru Kusajishi. She has been part of the 8th Division since childhood. She was mentored by Lisa Yadomaru. She has black hair blue eyes and wears glasses. She is usually seen carrying a large book. The book and glasses gives her the look of a librarian or teacher. She is also an avid reader.
Nanao Ise seems to be a very serious Shinigami. Her captain Shunsui Kyoraku teases and flirts with her. These antics make her angry and she ends up chastising or hitting him. When she is really angry she takes off her glasses which frightens everyone who sees it. Shunsui is lazy as well so Nanao has to do his paperwork and remind him about his duties.
Nanao seems to rely on magic rather than the more traditional shinigami tactics. In this regard she is similar to Yachiru Kusajishi and Nemu Kurotsuchi. Nanao serves comedic purposes by being the straight woman to Shunsui Kyoraku, Yachiru Kusajishi and Rangiku Matsumoto.
