I completely missed that detail! Thanks for pointing that out as a reminder!
Totally understandable to get, it's such a weird decision for these guys to make - especially now that we know they're suffering from a manpower shortage when it comes to special classes. Like I understand using women to threaten the guys, but is that really worth actively hamstringing 50% of your potential fighting force???
And this is done as part of the summoning process, so they can't even
check to see if the class the women would have had would've been worth keeping.
Like even if they want to keep the whole "force a relationship through sex with a slave so the summoned people stay attached", why couldn't the slaves just be native inhabitants? With how scummy this leaders are I'm certain they could get a pack of slaves and throw them in the prisons with the summoned heroes instead, and that way the summoned women could still be part of the war effort.
