I'm confused too. I have a vague idea that the 3rd mankind is humans and heaven and hell have somehow merged to manage it. Still it appears as both the angels and devils come from the same stock of beings because they are interbreeding with each other. An angel and a demon make a pair who reform/enforce people who have gone awry. But they also seem to battle actual monsters and I don't know where these come from. I myself also didn't understand the business with the cube in s1 and now the flowers in s2 (except they make you horny). I got the impression that there is no law against the marriage, but most see it pointless.

ok so ill try to explain it best i can since i myself am still kinda confused by the story too lmao so basically god built the heaven & hell roman company because there was mass unemployment on the heavens and im guessing hell too, so angels and devils work together on the company to keep safe the 3rd mankind, amongst other things regarding humans and their creations but the plot seems to be mostly about the 3rd mankind anways. The 3rd mankind is the creations that humans built over the years like the character in a book or movie, basically fictional characters. Sometimes some of the 3rd mankind stray away from their original story so they kind of get corrupted (??) idk what word to describe it as but they’re not the same person/thing they used to be which is where the reform/enforce teams come from where they try to revert them back to their original forms. There’s other teams too but idk what they so since the author hasnt rlly gotten in depth. Also its not against the rules to be gay, since various couples have appeared that are of the same sex and not even the main ones but also some extras, so i dont think thats an issue. The whole marriage thing though is kind of pointless since angels and devils are immortal so whats the point of having a ceremony if they know they’re gonna be together forever you know so its more of a symbolic thing than anything. Also we do see God lmao hes that giant man with orange ish hair that always seems to cover up his eyes with a big halo on top of his head lmao. Im so bad at explaining stuff but i hope this helped a little bit >.<

H&H Roman company is a company formed by angels (who were born from gods breathe then angels went to reproduce sexually) and devils because of great unemployment rates in both heaven and hell to manage 3rd mankind who are the creation of human mind (basically fiction characters in fictional stories). The so called monsters are 3rd mankind which are what they are who reside within these cubes they maintain (there are also transporation cubes btw that exist and those are the ones delivered to boost mankind creativity). This company is ran by both God and Satan I reckon - it's a collaboration !! annnnd as for marriage as stated above - it's just an imported idea from the human world and most of them (angels/devils) don't see the point in it because they live forever while mortal beings (humans) live for a limited time so they want to tie their fate. Also I reckon Mon is afraid of Mananan's feelings towards him changing after a long time ~ that's what I got from rereading and actually taking notes HAHA

Thank you everyone for giving it the old college try but honestly I'm even MORE confused. 3rd mankind? So mankind has evolved two more times? Creationism and Evolution exsist together? What do humans look like now? Fictional characters? So if I go to earth it's populated with Lord of the Rings, Harry Potter, Little Miss Muffet characters? Or is it that humankinds fictional characters have taken on a life of their own and need to be managed? WHAT??? Unemployment in hell? God gives a shit about that because why? Also unemployment in hell, yeah right!!! Most of us are going to hell (if you believe in that) not Heaven. If anything hell will be overpopulated and Heavens gonna be a ghost town so I say unemployment in heaven is far more likely but whatever I digress. Maybe things are just lost in translation or maybe the concepts don't translate to English very well. Jeesy Chreesy I haven't even gotten to the monsters they battle, what are they? Where do they come from? If Heaven and Hell are cooperating then who's sending these monsters? Another God like deity? God himself just to shake things up? WHAT THE F*CK IS GOING ON???? LOL I'm not mad I'm just SOOOOO confused.

Just go with the flow man, go with the flow ╮( ̄▽ ̄)╭

I won't go too deep into it. to me it about a company god created, that's besically it. and there is two places - angels and devils that work together to balance each other in different places haeven and hell - it actually do make a lot of sense! angel's can't work alone on humans dasire's. they need a devil kind with them. and that's it mostly XD
I read this from the beginning but I STILL don't understand what's going on. They are angels? Devils? What do they do? What is their point? Were they ever human? Why can't they get married? It's just a symbolic ceremony, I don't understand. I feel like it would be against the rules because they're gay not because they're angels or demons or whatever the he'll they are. Can someone PLEASE explain what's going on. There's a company in heaven that's NOT run by God? Or it IS run by God but we never see him? SO FREAKING CONFUSED!!!!
