Tsubasa. . . . . . . . . .
Mary
Well, Mary isn't really down in the basement that often. . . . . as Tsubasa is hardly in the story. . . .
     Tsubasa is a brown-haired guy who dresses up as a girl. . . . . . much like how we would describe Mary (it's another wonderful basement joke).  Ahh yes, our froshmen lezbo. . . . . . Errr unfortunatly she sometimes hits on Akane much to Akane's displeasure.
