Kagihime

, or simply Kagihime, is a Japanese manga written by Kaishaku which was serialised in Dengeki Daioh. A 2006 thirteen-episode anime produced by Trinet Entertainment was adapted from the manga.

It was one of many anime works influenced by Lewis Carroll's Alice in Wonderland as the story focuses on the completion of a third Alice book, The Eternal Alice.

Plot
One night, Aruto Kirihara was writing his own copy of "The Endless Alice" until he saw a girl leaping through the night sky. Believing her to be the Alice he writes about, Aruto follows her to a library where he sees her fighting with another girl. The next day, she reveals herself as Arisu Arisugawa, an Alice User, capable of transforming into a kemonomimi bunny girl that uses a key in fights against other Alice Users. The keys are used to unlock the stories in other Alice Users's hearts, where the defeated loses her story and can no longer be an Alice User. The overall goal of this battle royale of Alice User is to defeat them to finish the Endless Alice, and will be granted a wish. Thus, Aruto's story of Alive envelops more than what he can imagine.
