Kanon: Season 1

Yuichi visits his cousin for the first time in years and discovers a haunting fact: he has no recollection of any previous visits.

The pieces of the puzzle that might explain the gaps in his memory begin to appear—a beauty with blazing tresses; a girl with the winged backpack; a sword-wielding demon slayer.

Now, Yuichi must put his missing past together in the vaguely familiar present.
