This is a free preview of the novel's beginning. (link above description)
In which a cat becomes a butterfly...I mean, in which a little girl tries to stop a cat from seeing a new dream...nah, that's really vague.
A kitten perishes from one mistake, a little magician girl tries to fix that mistake, but ends up forever seeing only the mundane for the rest of her enchantment-filled life. This is where the most fairy tale-esque, non-eroge story ever produced by TM author Kinoko Nasu begins.
