In a human body, trillions of cells work tirelessly to keep the host alive. "Hataraku Saibou Black" follows the battle waged by these cells against the owner's unhealthy habits, fighting to safeguard his well-being.

Humans are complex biological robots that are made up of trillion of cells, each with their own structure and function. Even a single cell cannot slack off. Scientists have come a long way in estimating the number of cells in the average human body. According to the most recent estimates, the number of cells in a human body is around 30 trillion. Hataraku Saibou Black is about a fight of these 30 trillion cells against the bad habits of the owner of the body to keep him alive.—Scientiiaa
