Yumi is the animated counterpart of Yumi Yoshimura. She is the second member with Ami Onuki and one of the two main protagonists of the series. She is voiced by Grey DeLisle. She has short light purple hair, looking like a growed-out bobcut. She dresses in a rock style with a studded choker and two handcuffs, a purple T-shirt with a skull on it, a black miniskirt, purple shorts and black/purple punk boots. She often shows her highlighted fang in official arts and a pilot episode, while rarely does in main episodes. Yumi's demeanor is not just like Ami's. She is sarcastic, cynical, vain, and gained with self-importance. She loves things like ninjas and anything else rough and tough. She rarely signs in any excitement as "she is too cool" to show it. For some reasons, she comes off as rude and insults others she sees as "not cool". Despite being similar age group with and more serious than Ami, Yumi is also more impetuous than Ami and rushes headlong into a decision before thinking. However, Yumi has a mature side, too, and for some reasons with Ami's childish obsessions. She also has a big heart and is willing to help while she can. It’s worth mentioning that fans of the show usually consider Yumi as younger counterpart of the animated duo than Ami, as real-life counterparts, Yumi Yoshimura(born in Jan 30th, 1975) is about two years younger than Ami Onuki (born in Sep 18th, 1973).
