Episode 5 (CaW CB)

"Overwork, Hair Loss, and Delirium" (過重労働、脱毛、錯乱) is the 5th episode of the Cells at Work! CODE BLACK! anime adaption.

Plot
After overcoming numerous obstacles, rookie red blood cell, AA2153 has now confidence in his work. One of AA2153 deliveries sends the rookie to the Hair Matrix Cells and bumps into U-1196 exercising despite her injuries. It's not in her nature to stay still.

The two reminisce about the battle between the Neutrophils and the Gonococci. U-1196 thanks the rookie for saving her life by distracting the bacteria. Moreover, the white blood cell tells the red blood cells that there were countless casualties on the Neutrophils' side during Gonococci's infection. As a result, Killer T Cells are overworked. She gets berated by the passing Killer T Cells. AA2153 tries to defend the Neutrophils, but the latter stops him. It's true that due to the white blood cells' dwindling numbers that they've put unnecessary strain on the Killer T Cells.

The Helper T Cells get an alert of an invasion of foreign substance in the blood vessels near the nasal cavity and send out the Killer T Cells despite the subordinates' warning.

AA2153 finds out that inflammation is found in the hair follicles. It seems the Killer T Cells have caused the incident. The latter has gone haywire and attack the Hair Matrix Cells after mistaking them for cancer cells. Their actions cause the hair to begin falling out.

To help stop them, AA2153 organizes the red blood cells to deliver oxygen to the hair cells, hoping to sustain them. But things get a lot worse when the deranged Helper T Cell releases Cytokines to make the Killer T Cells go even crazier.

Luckily, things soon calm down thanks to the administration of Steriods - depicted as battle droids that restrain the Killer T Cells and Helper T Cells.

Elsewhere a healed U-1196 overhears cells talking about the incident with the T Cells.

After saving the hair roots, AA2153 questions the point of working hard as yet another problem arises, this time in the urinary tract.
