Naive T Cell is patrolling the body for influenza virus proliferation. But since he’s never taken on the enemy before, he’s completely terrified and useless. He finally ends up fleeing the battlefield where White Blood Cell (Neutrophil) and the veteran Killer T Cells are fighting. Naive T Cell is filled with self-loathing until Dendritic Cell sees him and speaks to him kindly.

The body has been invaded by a mass of cedar pollen! Rushing to the scene so that he can eliminate the cedar pollen, White Blood Cell (Neutrophil) runs into Memory Cell. Memory Cell is a Lymphocyte who retains the immune system’s memories. Seeing what’s actually going on, Memory Cell is strangely flustered. “What the heck? This is just like the legend...” What “legend” is Memory Cell talking about?
