hello, i am interested in this RP, but i am a little confused about the premise.

is the idea to kill the heroes invading the underworld? Or just convert them to the demon side?

So the premise is that The Demon Lord[sup]TM[/sup] does a typical anime isekai premise and decides the world need some smacking around. Cue anime protagonst who gets summoned to this fantasy world and gets told to go save it with the power of plot armor.

Demon Lord is smarter than that. He's getting together a group of badasses whose job it is to go find out said anime protagonists and keep them from messing everything up. How you go about doing that is up to you, just as long as it gets done.

Basically, what [@Guy0fV4lor] and [@Dead Cruiser] said. 

TL;DR You're apart of Anti-Isekai Action and you gotta go fight plot armor by being genre savvy.
