Tasumi is Riley's best friend, who is of Japanese descent and has a crush on Jacobo and kissed him revealed in one episode. There is hint of Tasumi's crush on Jacobo in "The Truth Hurts" when she passes on a note in the classroom that asks Jacobo if she liked him and was crushed when he signed maybe. She wears a pink metal suit which resembles RoboCop. But during season two she no longer wears her suit. She claims her family is part of a crime-fighting team. (parody of Power Rangers/Super Sentai). She also has a list of people she hates. Riley is either on or off it. In the episode "Best friends For-Never?" it appears Riley first meets Tasumi in a broom closet when she was new at school and tried to get to homeroom but got lost. Tasumi was in the broom closet because she split her armor and was embarrassed, but Riley fixed it with the ducktape her dad made her carry. In the episode "Tasumi Unmasked", it is revealed that Tasumi is in fact a Japanese pop star. She moved to Pleasant Hills in order to escape the constant adoration of her fans and live a peaceful life, as Pleasant Hills was voted as the least culturally aware town in the world and she believed that nobody there would recognize her. However, in order to make sure that nobody recognized her, she wore a costume from a popular anime and used details from that anime in order to get a new history. That's the reason she always referred to things such as fighting giant monsters and so forth, but in reality, she never did anything of that sort. When her fans found out about this, she moved back to Japan for 2 weeks to record a new album until Riley replaced her band members with orangutans and she got kicked out by her new orangutan members because she has thumbs (even though orangutans do have thumbs). She came back to Pleasant Hills with Riley and no longer wears her armor, dumping it in the garbage. Under her armor, Tasumi has long black hair and a pretty face complete with a small mole. She wears a blue wig with her armor. She also has a brother named Roku.
