Sayuri Matsumoto

Sayuri Matsumoto (松本小百合, Matsumoto Sayuri) is the daughter of Seireitou Kawahiru and Rangiku Matsumoto, the result of their drunken affair occuring years prior to Rangiku's promotion to the Royal Guard. Having taken her mother's surname, Sayuri became a student under Hanzei Kurosaki.

Behind the Scenes
There are many reasons for this article, but mostly that most people expected me to do something along the line with Rangiku, for obvious reasons I've heard. So here we are. Sayuri's name (小百合) is japanese for the orange lily, which stands for "hatred/revenge".
