Yassan
She is a 16-year-old second-year high school student of Sanada West High School. Her friends and classmates call her Yassan, but since Ikushima once referred to her as Yasunaga-chan, this could just be a nickname. She is a classmate of Takahiro and Takahiro’s Friend, and a known acquaintance of Habara, Ikushima and the Self-conscious Woman. A girl who wanders by the riverbank in search of her fated encounter, which is an act from a novel she is writing, she happened to chance upon Hidenori who parallels the man from her novel who has the power of the wind. Although she can converse casually with her classmates, she speaks profoundly around Hidenori in hopes of generating a fantasy scenario. She gets furious and violent when this fantasy is disturbed. She develops a strong crush on Hidenori.
