All this unnecessary risk just to reveal the enemy commander has a shield that can stand up to magic and magical swords. Selena hasn't even used any attack from the sci-fi side yet. They have energy rifles that they barely used, why? Now is not the time to be hoarding ammo. It is precisely the time to be using it. Rapid shooting guns made swords obsolete, but I guess she wants to play fair with more primitive fighting methods for some reason.
This is the perfect opportunity for a "parry this, you filthy casual" moment... don't miss this chance, mangaka. Already missed the chance for an Indiana Jones-style gun vs sword meme "fight" that ends in 1 second. If the objective was to strike fear in the hearts of enemy soldiers and win more admiration from allies, then a merciless curbstomp with overwhelming force would've worked better than a flashy but generally fair fight.
Corinth->Conlinto->Collins
Yep, feeling even more sure this is trolling. There is no possibility コリント would ever romanize to the latter two. Not even MTL would get this wrong, it has to be intentional given that the licensed title has "Corinth" in it. Next chapter it's probably going to be different again. Corinto would probably be in that list at some point...
