Sabikui Bisco, Vol. 7 (Light Novel)

"All across Imihama, people have begun sprouting feline ears and tails, and adopting bizarre speech patterns. It seems the Ultrafaith Arrow Bisco and Milo fired at Kurokawa opened a gateway to an alternate dimension full of--samurai cats? These katana-wielding kittens are being tormented by an ancient adversary who also happens to be the cause of the cat transformations back home. But as much as Bisco would love to put an arrow between their eyes, it turns out it's pretty hard to draw a bowstring with cat paws. Can the Mushroom Keepers defeat this feline foe before their nine lives run out?"--
