Neko-senpai to Nekokaburi-kun

The school's most popular senpai is actually a cat!?

Kani loves fluffy animals and one day he picked up a white cat that was totally covered in mud. He brought the cat home and fell asleep while looking after it.
When he woke up, the one in front of him wasn't the cat, but was Nekogami, the school's most popular senpai instead!?
