Bad Cats (Ikuto Fanfic)

Sora Kimura is pretty much a loner until a mysterious Ikuto Tsukiyomi comes along. She was a traveller around Europe with her only friend, Mika, her Chara. When Ikuto explains his half-truthful situation, Sora offers to help. Ikuto brings her along back to Japan, knowing she has intense power; the Felidae. However, there is a new threat in Japan; the Nonentities, beings of darkness that are created by Charas transforming to the opposite of what you want to be. And Ikuto knows that Sora and four others around the world can stop this.
