@Sandy Yes and no, i actually though that this happened chapters later, but now that i remember, the robot-looking girl that i mentioned in my spoiler in chapter 21 was actually another thing and was defeated by the MC's second body, the girl in the cover, not the MC himself, So yea, after the mc defeats this thing, he then bring her to his ship to study her, he then modifies her, so she is but she is not, its more like an upgraded version of her body structure and the material shes composed of (Like bones and organs), or perhaps he just copied her "Plans" and made a full blown new body, its actually all secret, so we dont get to see what he does to the body
