Konomi Tamura is an artificially created female super-soldier within the Wet Prope military project, part of a five-member unit of genetically enhanced pilots designed to operate large combat mechs called Skelters under Otsuya Funagai's supervision. She possesses ochre hair and grey eyes. Her reserved and shy personality contrasts with the more assertive Misaki Kashima, though both regularly undergo combat training exercises piloting their Skelters.

Tamura holds the designation as the top student in the unit's beginner-level pilot class. She pilots the yellow Skelter Cosmos-03, equipped with a panzerfaust as its primary weapon. The unit's purpose is combating colossal, non-terrestrial organisms resembling giant squids that threaten locations such as Tokyo. Her narrative function centers on her participation in these missions and her ongoing training regimen.
