Langerhans also have a second self-protection function, shielding the skin from ultraviolet and dryness. Mr. Langer told AE that she must be careful since they are close to the epidermis. They can not tell when and at what time the outside enemies might attack.
AE agrees with Mr. Langer and realizes that she has to focus on her own work. Along with other Red Blood Cells, AE heard a sound wave. Langer is wondering what kind of sound is this. When they look up, they saw two saw chains invading the area, and they notice that its a mosquito man. Mosquito Man started to destroy everything and sprayed a gas that puts other cells to sleep.
AE manages to hold in, but all the Red Blood Cells started floating. They are being taken away, but Langer and AE remain. Mr. Langer picks up the left mask when others were taken, and it covers his face automatically. All the Langerhans cells started rampaging, destroying the Red Blood Cells. B cells notice that the virus has infected the Langerhans cells. Mast says the signal and thinks that she has to release the Histamine to solve the problem.
