ppl miss understanding a lot from the translations, its not pure iron as iron itself, hes talking about how much sun it absolved into itself, and how much pure it is, as before he also stated his sword is made out of his flesh
yeah i definitely don't see rock pillar winning, at least not without some sort of serious injury. this should be a good fight though. and I can't see the rest of them will just wait there for Himejima to finish the job. so until they move, the fight won't be over.
@Someone2Love he should be fine. even UM1 is wondering how to kill him since he's not dead yet. that makes me wonder though, what will happen to genya if he gets a chunk of UM1 meat? that sounds risky as heck since he's that strong, but it's a food for thought. what if one of the pillars managed to slice off something and he eats it?
