Final Eight Arc

Kei appears to help the Achiga mahjong club get stronger in order to prepare for their semi-finals match. She was the only one to answer their call to play and ended up calling some of her friends from the individual tournament to help out. At halftime of the side B quarterfinals, she asks the Achiga girls if they are okay not watching the matches and says that there are others who might want to see their match. After Rise says that its alright, Kei says that its fine but there is a tv in the lobby just in case.

She appears in a flashback of Satoha Tsujigaito when they played each other from the Inter High Individuals last year.
