Exactly, which is why I hope she appears in more volumes, and she does more than just become a point for Tsubaki and Yuuto. You know fight, help, anything really. Although I really wish Ichiei didn't have to put her with the sword project, as I feel that just brings out old wounds. If he really needed to give her a back story, maybe he could have put Tosuka as an orphan who Kiba met, while he was training under Souji.
