Ayu Tsukimiya is a young woman with a childlike appearance, who remembers Yuichi after he introduces himself. They had met seven years prior and she might be able to shed some light on Yuichi's loss of memory. She's the main heroine in Kanon. Ayu is the same age as Yuichi, but acts younger. She often uses the word "Uguu" when she is upset or mad. Ayu is the main female character in the anime although it may not appear like that initially. Her favorite food is hot Taiyaki.
