is a second year student who is the current president (and initially, the only remaining member) of the Half Priced Food Lovers Club. She is one of the strongest wolves of the west, leading her to be known as the Ice Witch. Her title comes from her accidentally almost buying a beer called Ice Cold because she liked the design and assumed it was a normal drink, in addition to it being on sale. While usually calm, she's very innocent and does not particularly know a lot outside of bento brawls and can sometimes be pretty clumsy. She can be very stubborn as well, especially when it involves a challenge from another wolf. Sen, however, does have a good heart, preferring not to judge people by appearances or hold any grudges. She doesn't seem to have any dislikes, besides bento brawlers who do not follow the rules and boys who ignore girls that have been hurt. Despite Yō having many fantasies of Sen, she appears to be oblivious to this particular side of him. Regardless, she cares for his well-being and often shares bento with him, hinting that she may like him.
