Nishina-san, the part-timer at Yukichi's regular supermarket, recently quit her band. And now she's accidentally discovered that Yukichi, the mentor whom she so idolizes, is not actually a man in a cat suit--he's a real live cat! That changes...nothing?! Yukichi is still teaching Nishina-san all the ins and outs of housework and she's still giving him guitar lessons in exchange. Looks like "Operation: Turn Nishina-san into a Self-sufficient Masterful Girl" is still a go!
