A tomboyish third-year student at Seiho Academy and the president of the Gunpla Battle Club, as well as the leader of the Try Fighters. She and Yuuma Kousaka were best friends and used to build Gunpla together. They both had the same dream of competing in the World Championship, and made a promise to fight in it together. Fumina is a very caring person. This is however her weakness in Gunpla Battle, as she prioritizes helping her teammates. Fumina has a strong drive to accomplish her goals, but also believes in the value of teamwork. She is also a very capable tactician, often directing her teammates in the battlefield. At school Fumina is the target of affection for many male students thanks to her look and personality. She however holds feelings for Sekai Kamiki, and has shown jealously on many occasions where other girls displayed affection for him.
