Keysa Oathword. An ordinary woman who hates furry creatures. While visiting her best friend Reeny, Keysa noticed an explosion in the cat's eye. However, the explosion was no ordinary explosion. Vaguely, Keysa could see another world in the explosion. After that incident, Keysa felt different than usual. Keysa felt being watched by someyhing. Until the next night, Keysa was reunited with the cat outside her bedroom window in a floating state. The worst part was that the cat could even talk. Shocked by this fact and the cat's insistence on coming with her to another world, Keysa fell out of the window. As soon as Keysa looked back into the cat's golden yellow eyes, the moment she opened her eyes, Keysa was in another world. A sweet, fairytale-like world filled with furry creatures.
