A cat with bad sleeping habits accidentally draws a magic circle and summons the "Nicotine Demon"! However, the demon can't stand the sheer dirtiness and filth of the room and bounces back immediately... While the world is saved by the filthy room, the cat who wants to earn a lot of money gets a job cleaning a shady underground facility through a temp agency. This guy always ends up with jobs like that. Meanwhile, Penpen Cat's landlord tries to kindly welcome him back to his apartment after his house was swept away by a typhoon, but an unexpected accident occurs. Don't stand up.
Yanineko joined the kids' soccer game in the park, but was reported as a suspicious person. Well, that's to be expected. Back at his apartment, he was once again yelled at, lectured, and ordered to quit smoking by his landlord. But this guy shows absolutely no remorse. In the end, he's made to weed the garden instead of paying rent, but Yanineko's gaze is fixed on the landlord's cabbage patch... Whether he smokes or not, leaving Yanineko alone never leads to anything good. That's the lesson learned this time (sort of).
