Japanese title: 東方妖々忌

The Japanese title for Perfect Cherry Blossom, Youyoumu (妖々夢), echoes the name of Konpaku Youmu, who debuted in the game. This story's title is a parody using the name of her grandfather, Konpaku Youki. An equivalent pun on the English title might be "Perfect Geriatric Blossom".
