Ryouhei Shimokabe, a dwarf-sized researcher, created a specialized combat costume to oppose the criminal organization Demon Seed. He initially engineered a Patlabor-esque robot suit anticipating a male pilot, yet upon discovering the recruited idol was young girl Maron Namikaze, he repurposed the technology and supplied it to Demon Seed instead. Shimokabe displays pronounced arrogance and immense pride in his engineering work, especially the mechanical systems he develops. His core motivation arises from wanting his creations deployed for their intended combat purposes. He becomes visibly disgusted and disillusioned when Maron is leveraged primarily as a pop idol singer for public relations rather than consistently deployed as a frontline fighter against Demon Seed, perceiving this shift as a betrayal of his technical vision.
