園城寺 怜

Toki is a third-year at Senriyama Girls' High School. Her closest friend and caretaker is Ryuuka Shimizudani. She used to be on the school's third team but after her hospitalization, her ranking increased. Toki is physically weak, she is constantly being cared for by Ryuuka. Though she cares for Ryuuka and other members, she doesn't want to become a burden to them as she is always being hospitalized.

Toki has the ability to see one turn into the future, which she says she received after first being hospitalized. This allows her to consistently get an ippatsu after declaring riichi, which other players are shown to be aware of. She also has the ability to see two, and even three turns into the future. When Toki first tried to see two turns into the future, she fainted, resulting in Ryuuka making Toki promise never to try it again, but she practiced it in secret and until she could do it without fainting, although it still takes a severe toll on her health.
