Cereus Kin

This is a highly heat-resistant soil bacterium that can cause food poisoning. It appears in episode 6 in a humanoid form with tentacle-like limbs. This bacterium invades the body through wounds, especially when a person collapses from heatstroke. It looks down on White Blood Cell U-1146, whose functions are impaired, and cruelly insults him by spilling barley tea in front of his collapsed form. Due to its cowardly personality, it takes advantage of weakened opponents. However, after medical treatment improves the body's condition, the recovered U-1146 defeats it.
