The company Megahouse revealed a new line some time ago called Desktop Army. It is a line of small figures with the exact same play-pattern as Busou Shinki: small robot girls, with modular armor and weapons.
The difference is, Desktop Army are trading figures: they're sold by the case on places like Amiami, with weapons and armor unassembled and unpainted, model kit style.
The first wave, Sylphy-series, was designed by Blade (yes, that Blade).
The second wave, Chrom-series, was designed by Tanimeso (yes, that Tanimeso).
The third wave, most recently revealed at Summer Wonfes 2016, is the Millennia(?)-series, designed by Yanase Takayuki (noticing a trend here?)
