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 new strain 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, using Coagulase. A squad of Monocytes appears at the broken artery wall, and then shed their hazmat suits to reveal that they’re Macrophages; Monocytes being one of the many roles they play. The Macrophages start attacking, and easily defeat the invaders by scaring the bacteria from being combined.
