Mafuyu Oribe

Mafuyu Oribe is the adopted daughter of Yuudai Yamanobe (the previous dean of St. Mikhailov Academy's) and the self-appointed protector of Tomo Yamanobe. Mafuyu is so proficient in kendo that she carries a wooden sword with her at all times. She has had to endure hardship on a daily basis in the form of her classmates harshly picking on her and especially Tomo Yamanobe due to a loss of status when their father disappeared. This changes when she encounters Sasha for the first time, where he starts living with her and is pitted herself in the fights between Qwasers. Mafuyu is an average girl with shoulder-length maroon hair and purple eyes. She is always seen wearing her school uniform and holding her kendo sword, but she changes her outfits naturally. She is often made fun of by Sasha for having small breasts, one of the smallest in the series along with Hana Katsuragi, Ekaterina Kurae and Fumika Mitarai being the only ones smaller than her before hers increase. In the manga, Mafuyu's breasts continue to grow throughout the story. In the second season, after training with Katja, Mafuyu eventually grows into a G-cup which is revealed in Episode 6 of Season 2. Mafuyu is a strong-willed, determined and cheerful girl who likes to be independent. She won't hesitate to help others. Mafuyu gets embarrassed easily, but she can be surprisingly kinky, especially when it comes to Sasha.
