Suzu is a second-year at Himematsu High School. Her mahjong play is somewhat inconsistent, and she is often bullied by other members of the school's mahjong club. Suzu was added to Himematsu's tournament team by acting coach Ikuno Akasaka because her teammate Kyouko believed in Suzu's playing potential. She worries a lot about her opponents' moves and actions during her play, however, she soon sheds this carefulness and becomes confident in her abilities once they activate. In her freshman year people tended to bully her. It is hinted that she is close with Kyouko.

While playing with Himematsu's rules, Suzu is considered a weak player and is always in last place. However, according to Suehara, if the match is simple and only counts incoming points, she is very skilled, even coming in first. Also according to Kyouko, she plays and wins explosively, and has the ability to win "explosive" hands, especially when she is playing against stronger opponents. Yuuki was warned to be careful when Suzu starts winning with 7-8-9 tiles (chanta). When her fuse is lit, she goes on a winning streak comprising of relatively high paying hands (often leaning towards chanta and junchan tiles), eventually reaching expensive hands comparable to that of Yuuki's closed-riichi hands in the East rounds, being iishanten for a yakuman on the first discard. However, she is not above taking the cheaper win if it comes along before her expensive hand. If someone else wins during Suzu's renchan, her fuse is stopped, but this only delays the explosion.
