Senko

Follows the lives of Nekota, a human boy, and his younger sister Neneko, a cat, as they bond and try to overcome the differences in their species.

More lovely days ensue for the fun-loving kitten little sister Neneko-chan and her beloved big brother, the human Nekota-kun. The black cat Coco-chan and Tomo-sensei--the air-headed teacher--come along for the complications this time, too.

Human boy Nekota is adopted into a family of anthropomorphic cats and though his life is weird, he is loved unconditionally by his younger sister Neneko.
