Kanon

Yuuichi Aizawa returns to his childhood home in the northern town after a 7-year absence, as his parents have relocated to Africa for work. Yuuichi's memories of this place and its residents have inexplicably vanished, leaving him with little connection to the people around him, including his cousin Nayuki. While moving into his new home, he discovers a red headband that sparks his interest and sets him on a path to uncover fragments of his past. As he explores the town, he encounters various girls who seem to be connected to his forgotten memories.
