龍門渕 透華

Touka is a second-year student at Ryuumonbuchi High School and is the president of the mahjong club. Touka is the daughter of Ryuumonbuchi High School's principal and her grandfather owns the school.Touka's playing style is similar to Nodoka in that she plays a fair amount of online mahjong. She uses a careful approach to obtain easily winnable hands. What differs is that she uses her emotions to ride the flow of the table when going up against strong opponents. However, Touka can enter what her friends call a "cold state" where she utilizes her flow control without the hindrance of emotion. This increases her ability so much that she can easily dominate very strong opponents like Saki, Koromo and even Fujita. The problem is that in this state she loses consciousness after a few games and cannot recall anything she did while in her cold state.Touka is an eccentric girl who loves to stand out and hates it when others stand out more than her. She is an ojousama, having a personal butler and maid, and is very ladylike most of the time. However, this is thrown out the window when she interacts with Nodoka. Besides being somewhat jealous of the attention Nodoka gets, Touka derives physical pleasure when playing at the same table as Nodocchi. In contrast to her somewhat snobby attitude, Touka cares a lot for others, especially Koromo Amae, as demonstrated by her motivations for entering the team tournament. She is very motherly towards her cousin Koromo, yet dislikes being told so.
