Welcome to Nekopumi Academy. A school just for cat girls. It is located in a secret place from the eyes of humanity. Founded seven years ago by a woman who was a scientist studying genetics. She also owned and lived with about several cats. Did I mention the strange potion she was working on? Well it was a strange potion she was creating to ensure that cats would have longer lives. It happened when she went out one day...

One of the cats, Lennie, was a very curious little kitten. The potion stood on the highest shelf in the house, curious she leaped onto it and fiddled with the strange vial of orange liquid. Until she fell taking the potion with her. When the scientist returned she found the potion on the ground, it was all over the floor she really needed to put a lid on these things. Her surprise however, was the cat girl now sitting right across from her.

...

It was at that moment she had a brilliant idea to change all the cats into cat girls, it seemed their lives lasted much longer as well as keeping their feline abilities. She decided to create a school to educate these young kitties about their new bodies and how to adjust to them, for some reason the potion only worked on females...
