From today on, I am a sniper...!? Five girls whose limbs were taken away and equipped with tactical weapons called "LBXUnit" - "Armored Girls". The mission of these girls who were chosen to be the transferors is to sweep and annihilate the metal life forms, Mimesis, which are constantly eroding and proliferating across the multiverse. The mercenary life imposed across time and space is a school trip that allows you to glimpse the "hope" and "despair" of the world and gamble your life!
