What do you mean by send the monsters to their territory? Are you referring to the Job section? And i understand and agree with the not selling part. I just wanted to know the idea and use of the black market. But thanks for clarification.
As for the text for story at the beginning believe you can keep to a minimum for now. Like Walking in real world , Storm set in , Got Knock out ,Woke up in another world, Demons are attacking, Rebuild by breeding and defending. Here is building, breeding and front gate to worry about. (This is just my thought process. I grown up knowing simple is better but that is just my opinion)
And sure ill be happy to give feedback when i am available irl. Ill join in and comment when needed.
My previous explanation was a bit unclear. What I meant is (as the goddess statue will later explain) the summoned monster girls are naturally allies of the lord. At this point, the lord’s territory should be their home. By assigning them work (through the Quests system) or directly moving them out of the temple, they can live normally in the territory. Once settled, they become part of the territory’s population, contributing to labor, military strength, and other stats, just like regular human residents.
