恋の花咲く百花園

The heroine happens upon a white cat, who reveals itself to be a spirit residing in the “hundred flower garden”. His wish is to see the garden restored to what it once was, so he asks for the heroine's help. He bestows upon her the power to hear the voice of plants and to feed them people's positive energy, so that they can grow. Confused at first, the heroine soon gets to work on restoring the garden.
