In Kotonoha no Niwa, she is a mysterious 27-year-old woman Takao meets one rainy day in the garden. She spends her days with chocolate in one hand and a beer in the other. Their rainy morning meetings begin after she responds to Takao's greeting in classic verse.

In Kimi no Na wa, she is Mitsuha, Tessie, and Sayaka's Japanese literature teacher. She teaches them the word "Kataware-doki," meaning "twilight" in the local Hida dialect.
