There is so much satisfaction in seeing people get what they deserve.
This summoning practice is screwy on so many levels. You are ripped from your own life and brought to a world where you either die early, or you are enslaved to be a fighter. No, I don’t pity the three assholes in this arc, since it doesn’t excuse their obviously corrupt personalities, but someone should address the fact that this is maybe not the best way to get good fighters. They aren’t loyal, and they’re resentful...not to mention you may get complete psychos. Seems like maybe spending the magic, money, etc in another direction would be a better use. Like...naming monsters and have them be loyal to you...?
Dunno why the soldiers are shocked - it said specifically that humans aren’t that strong compared to monsters, which is the reason for summoning otherworlders to begin with.
