One of Kashima's two bodyguards and is Terumi's younger sister. She is by far the cutest of them all (Even Manami thinks Yumiko is cute!). She only participated in one V.G. tournament: the bout of cabalistic goddess. A few years later, she made a great comeback in V.G. MAX (Good move, GIGA!)

     Even though she has a Japanese name, her heritage is very much chinese. She works in a Chinese restaurant, dresses in Chinese clothing, and is skillful at chinese Kung Fu. BTW, whatever Yumiko says in Chinese is not real Chinese (there's this thing about Japanese not getting enough influence in the Chinese language).

     Before the time when Yumiko moved to work in Japan she once worked as a dancer in Hong Kong. She hopes that one day after she finishes what she has accomplished in Japan, she plans to return and live with her grandfather in China.
