In the back building of Weissman University, a young female student can be seen brooding over other students. Whether they are fellow students or professors, they dare not approach the girl. For she is Rin Tokugawa, the top student of the Faculty of Supernatural Martial Arts and the daughter of Akira Tokugawa; Captain of the Orca Squad from the P.I.I with a brutal nature. Her mother's traits have descended onto Rin, causing her to lack compassion as well.
