An [i][[iDOLMASTER Cinderella Girls|iDOLM@STER Cinderella Girls]][/i] character in the Passion (Yellow Sun) category.

Yumi is a home gardener who seeks to become a flower themed idol. Her idol costumes always have a flower theme, with newer cards are getting more elaborate with it. She always has flower in her hair when doing stage work. Every single card she has, with exception to the New Year cards, has her smiling in them.

In the tie in Cinderella Girls Theater skits, Yumi is a friendly girl who loves flowers and plant life. She seems to be a friend of [[Abe Nana]], although she has come dangerously close to finding out about Nana’s true age. She successfully creates a chocolate carving of a rose, and gets [[Miyamoto Frederica]]’s “Frederica” song stuck in her head when they continue baking. On Halloween, she dresses as a vampire and threatens the Producer to give her some candy or she’d bite him. He decides to allow her to bite him, but she is entirely too embarrassed to do so. In the end, the Producer gives her a bag of sweets.

Due to her popularity, she was selected for the 9th set of CINDERELLA MASTER CD series, alongside [[Ninomiya Asuka]], [[Ohtsuki Yui]], [[Nakano Yuka]], and [[Igarashi Kyoko]]. She is voiced by Kimura Juri [木村 珠莉].
