Cells at Work!! The Return of the Strongest Enemy. A Huge Uproar in the Body’s Bowels!

Ippan Saibou envies the praise that immune system cells like white blood cells receive for protecting the body. Wanting to be useful and recognized, he rescues a group of infantile-looking bacteria from a river current, ignoring the potential dangers. Meanwhile, Hakkekkyuu U-1146 detects the presence of these bacteria and begins hunting them.

Elsewhere in the body, NK Saibou searches for a dangerous antigen that the immune system has faced before—one that may have returned for revenge. As the bacteria grow and the old enemy reappears, the cells must confront a threat that could cause chaos within the bowels.
