just as i thought , this is a garbage manga .
- some random bratty demon : i can isekai all of you children from this demon world to the human world . it is the most greatest thing for you children .
- mary sue and gary stu : what do you want as the reward / the price ? you want gold ? money ? jewels ? diamonds ? some $ex with the boys and girls ? the "bodies" of the boys and girls ? our meat ? our organs ? our brains ?
- nah , I DO NOT WANT NOTHING AS THE PRICE . im in a good mood so will do it for FREE .
- ???????? why ? and why do you also isekai the mass-produced , retar* , brainless children in page 18 , panel 5 ? they can not survive outside of the farms .
- dont ask me , ask the stupid author .
this is just like the trashy plots in some isekai stories : the MCs instantly receive the most greatest , the most strongest powers in the whole world , but they do not have to pay nothing in return . some example : re:monster aka retar* : monster , isekai smartphone , game of familia: kazoku senki , .... , these manga-s are trash , waste your time with them at your own risk .
