Staphylococcus aureus (Manga)

AE3803 is rescued from a germ by a mysterious immune cell called Monocyte, who doesn't speak and wears a hazmat suit. Later, the nasal cavity gets invaded by a band of Staphylococcus Aureus. Vowing revenge for one of their number who was killed in "Scrape Wound", they combine their bodies into a powerful giant who is able to trap the white blood cells in a net of fibrin. A squad of Monocytes appears and sheds their hazmat suits to reveal that they are Macrophages; Monocytes being one of the many roles they play. The Macrophages easily defeat the invaders.
