Toki Onjouji is a third-year at Senriyama Girls' High School in North Osaka. She's a supporting character in Saki: Achiga-hen episode of side-A and came out of nowhere to be named one of Senriyama's aces for the 71st Inter High School Mahjong Tournament—which caught a lot of people off guard since she wasn't really known before that.
Physically, Toki's pretty fragile. She's constantly being looked after by Ryuuka, and she spends a lot of time in the hospital. She cares deeply about Ryuuka and her teammates, but that's exactly what worries her—she doesn't want to be a burden on them because of her health issues.
