Compiler

The Igarashi brothers, Nachi and Toshi, have their lives turned upside down when two stunning women from another dimension—Compiler and Assembler—enter their world. Originally dispatched to subjugate Earth through a contest of destruction and creation, the pair instead conclude that everyday existence in this realm is far more appealing than conquest. They move in with the brothers, and over time, quiet affections begin to grow: Nachi finds himself drawn to Compiler, while Toshi develops similar feelings for Assembler, though neither side can muster the courage to speak openly about them. Back in their home dimension, the authorities who sent Compiler and Assembler are furious at what they perceive as outright betrayal. In response, they deploy two assassins, Bios and Directory, to eliminate the defectors and set the invasion plan back on course. From that point on, the real misadventures unfold.
