Neko ni Tensei Shita Oji-san

When Fuuta comes home tired at night, all he wants to do is spend time with his new cat. All the mysterious habits and mannerisms of house cats are carefully reproduced in this relaxed and cute comedy about living with an adorable furball!

Takes place in the year 2200, where Japan has become a land of cats as the human population's birth rate has declined. In this future world, cats can talk, learn, and work. The story follows a high school girl and her argumentative cat.

The story imagines if Japanese historical figures such as Queen Himiko, the warlord Oda Nobunaga, and samurai Sakamoto Ryouma were cats.

When Saku took in a stray black cat, she never expected that he would become the equivalent of a housekeeping life partner. But Yukichi, a giant cat who towers over Saku, is not your ordinary feline. He takes great pride in his culinary skills, and a good sale at the supermarket always gets his whiskers twitching. Saku may not have her act together yet, but at least she has Yukichi!
