Kanon

Yuichi Aizawa returns after seven years to the city he visited as a child, moving in with his cousin Nayuki Minase and her mother Akiko. He barely remembers anything from that earlier visit, and Nayuki's attempts to jog his memory go nowhere. As he meets the people connected to that time, and begins to sense the city's quiet supernatural undercurrents, fragments of what happened seven years ago start coming back to him.
