Nyanbo!

The "Nyanbo" are square-shaped creatures with ears and tails who arrived on Earth from space. Among them is Tora, who hopes to fix their damaged UFO and go back home, along with his sister Kotora, the clever Shiro, the troublemaker Mike, the enigmatic Kuro, and others. These Nyanbos now live carefree lives, much like cats, sometimes causing mischief in hidden corners of the world unknown to humans.
