Hataraku Oniisan!

College classmates Tapio Chatorazawa and Kuehiko Roshihara are two cats earning money through a succession of part-time jobs. Tapio approaches each opportunity enthusiastically, while the more reserved Kuehiko offers a contrasting outlook on their working lives.

Delivering parcels, staffing shops, cleaning windows, and helping at an aquarium introduce them to animal coworkers with very different personalities. Every workplace has unfamiliar routines and hidden challenges, giving the pair plenty to learn before their next shift sends them somewhere new.
