姉帯 豊音

Toyone is a third-year at Miyamori Girls' High School. She is a very tall girl dressed in black and is a huge fan of Komaki Jindai. Despite her intimidating appearance, Toyone is a fairly lively girl, getting excited over her opponents matches. She is a rather cheerful character, but can be prone to moments of extreme emotion when speaking about how grateful she is for her team. She tried to give encouragement to a devastated Aislinn after her defeat, showing that she is affectionate towards her teammates. 

Toyone is very confident in her mahjong abilities. Coming from a small village with very few people, she learned to play Mahjong by setting up the tiles and watching matches from TV, as it was the only fun she could have. Toyone has several abilities relating to the rokuyou, which are six days in the Japanese calendar that have specific circumstances determining whether they are lucky or unlucky. One of her abilities is Tomobiki, which allows her to pair her final tile after making four calls (in mahjong terms, a naked wait.)

Her third ability utilizes Okkake riichi, which enables her to win off another person who had previously declared riichi by declaring riichi. As an added twist, this ability is also coupled with Ippatsu, where the winning tile is immediately discarded by the riichi declarer.
