2nd year High School (U.S. 11th Grade)
She's cheerful, and she gets respect from the fact that her one-track mind tendencies reflect in the seniors; a serious girl with a good eye for trouble-spotting among the juniors.
3rd year High School (U.S. 12th Grade).
Exchange student from a Florida "sister" school. She comes to Japan during her 3rd year of high school, and just for one year.

When an English lesson in each class turns up, she goes around able to speak her native language.
2nd year High School (U.S. 11th Grade)
One year ago, it was "Messatsu!! (Annihilating Kill... had to say it in Nihongo! --ed.) The hot blooded-fighting gang! The flaming 100th certain victory battle!" Shinobu took well-known strong people from the metropolitan area's schools and city dojos as opponents and kept racking up the wins, but after 99 people had watched her fight, she finally tired out. At the Ryouran Girl's Institute, her opponent was Tamaki Shindou. After that she knew of the Mega Fight; she lost to her opponent, who she knew was the overall winner. This year, she will enter the Mega Fight and fight last year's winner to prove that she is the strongest.
