I really like your FoE art. I haven't finished Horizons yet, but I'm fairly confident that BJ's legs get replaced at some point based on the fact that her legs are replaced in half the art I see of her. It's probably a bad idea to look at fan art before finishing the story, but so far there haven't been any huge spoilers anywhere.
My thoughts exactly. 52 chapters in and we still haven't found out exactly what EC 1101 does, what causes ennervation, or anything, really. All we really know is that shit has to get even more fucked up before anything gets better.
