Kanon

Yuichi has been apart from his cousin Nayuki for years. Upon his return, he discovers that any memory of their visits has vanished. He struggles to adapt to surroundings that feel only half-remembered, while gaps in his recollection gnaw at him as deadlines close in. Clues emerge: an eerily silent beauty with blazing red hair, the enigmatic girl with a winged backpack, and the sword-wielding demon slayer. It now falls to Yuichi to uncover how these pieces fit together.
