Senoo Kaori♀

Kaori is a second-year at Tsuruga Academy and Kanbara's childhood friend. She joined the school's Mahjong Club as the fifth member, making it possible for them to enter into the tournament. Kaori is a very shy and ditsy girl who gets nervous easily. Despite her apparent status as a complete beginner in mahjong, she appears to have a perceptive side, having noticed that Saki Miyanaga wasn't the least bit deterred during her match against Kazue Nanpo. She is shown to trust people easily which lead her joining the match against Mako Someya and others during combined training camp (in which they tricked her to get revenge).

Kaori is a beginner at mahjong her moves often confuse her opponents. However, her great luck allows her to win sometimes, and the fact that she cannot be read easily by opponents is another powerful factor.
