Aya Kurihara

This French-Japanese transfer student had a run-in with Yoshihiko when he looked for a ball that sauntered into the library's window. When he crawled to look for it, he knocked the stool where she was standing. Luckily he caught her falling...and after getting a feel of her "lumpy" side, he daydreamed about her... At the start of the second episode, she was the one secretly watching Yoshihiko from a library window. (Source: Wikipedia)
