"Ego" = "self"
"Entropic world" = "forsaken world"
"Cut" = "rend"
I think "entropic world" would be better suited as chaotic. Entropy has a very specific meaning in computer science/physics and it's rarely used outside of that. "Chaotic" is a suitable casual conversation adjective for "high entropy".
I'll check it out.
This is actually one of my biggest pet peeves TBH. Zoro wasn't always an idiot, preskip he was actually reasonably intelligent. In Alabasta he invented two factor authentication upon identifying an enemy with the ability to mimic faces. That's quite the impressive display of cerebral prowess.
By the end of the timeskip he was so thick it took him a while to decode Luffy's message and by Dressrosa he needed a complicated plan to figure out that he just needed to cut Pica in half. Currently, he's a full blown Luffy tier idiot. At the rate Zoro is losing brain cells, he'll be a vegetable before he duels Mihawk.
