Hataraku Saibou, in its basic sense, is Osmosis Jones meets anime. The manga and anime series follows the action and slice-of-life story of Red Blood Cell and White Blood Cell as they do their bodily functions and encounter antagonists along the way. The series has three spinoffs, Hataraku Saikin, focusing on bacteria, Hataraku Saibou BLACK, a mostly genderflipped and darker series set in an unhealthy body, and Hatarakanai Saibou, focusing on cells that don't work (aka NEETs).

This thread will focus on the main series, but discussion of the spinoffs are also welcome here!
