Description

Tomoki is a second-year student at Ryuumonbuchi High School. Hajime stated that Tomoki was like one of the elder sisters in their family. She was a top ranked player at an RTS online video game before Touka recruited her to their mahjong team.

Tomoki is a very quiet and stoic girl who only talks when she deems necessary, though she is sometimes mean to Touka when she is down, but Tomoki has never shown to have been rude to other people except Touka which implies that they are more family like. She's very serious except when she's being snarky. She has somewhat of a grudge against Kaori Senoo as her opponent, due to being defeated by her in the prefecturals.
