Over the years, many strange things have washed up on the shores of Windaria. Rick, a former swordsman, knows this all too well, having been found on the beach with a profound case of amnesia himself. Perhaps that’s why Rick takes a quick interest in Kaguya, a girl who arrives in Windaria in a similar waterlogged and memory-less condition. It soon becomes apparent that his swordsmanship will be needed to protect her. For dark forces are on the move, all of whom seem to be seeking Kaguya!
