In this new spinoff of the hit manga Cells at Work!, a newbie Red Blood Cell is one of 37 trillion working to keep this body running. But something’s wrong! Stress hormones keep yelling at him to go faster. The blood vessels are crusted over with cholesterol. Ulcers, fatty liver, trouble (ahem) downstairs … It’s hard for a cell to keep working when every day is a CODE BLACK! The manga and anime Cells at Work! showed you what happens when a young, healthy body gets in trouble … but what if the body wasn’t so young, and was never very healthy? This new take stars a fresh-faced Red Blood Cell and his friend, the buxom White Blood Cell, as they struggle to keep themselves and their world together through alcoholism, smoking, erectile dysfunction, athlete’s foot, gout … it’s literal body horror! Whoever this guy is, he’s lucky his cells can’t go on strike! Links: Official Twitter Manga Artist's Twitter Official Anime
