Cells at Work [BLACK] 

A manga about the hustle and bustle of cells trying to keep an unhealthy human host alive.

A spin-off of the popular Cells at Work series, this manga is about a human who’s riddled with health problems like smoking, alcohol addiction, and STDs. Just like it’s title, the tone is much darker and grimmer. It also gender swaps the main red blood cell and white blood cell characters.

Funny story is that before the anime started I had only read this manga so I was pleasantly surprised to learn that this was a spin-off specifically following an unhealthy human. I recommend watching the anime or checking out the original because the tone of this one is just too depressing.
