Kakura Kurumi

Kurumi is a third-year of Miyamori Girls' High School, and one of the three original members of its Mahjong Club. Kurumi is a bit of a snarky character teasing her teammates and opponents alike. She is also very childlike in personality and likes sitting on Shiromi watching the matches.

Kurumi does not declare riichi during her matches, thus opponents are not able to determine whether she has reached tenpai. Kiyosumi High School's Hisa Takei likens this to the stealth riichi of Tsuruga Academy's Momoko.
