Hey guys,
So I've been searching for this manga a few days now and I'm really frustrated - I can clearly remember the story and characters(no names of course), but it is neither possible for me to remember the tittle, nor to find it anywhere...
Yeah, so the story is about a son of god(?) going to the demon world. First he is sent as a messenger to the underworld because god(?) wants to let the middle world become heaven's property(sth like this I can't remember the exact thing) Then this really, really beautiful, long-haired(?) guy falls in love with the demon's lord and decides to stay with him in the underworld. But then they have some quarrel because there is people living in the "hell" who need light and so on...After this the beautiful angel was kidnapped and disappeared..Then after a lot of searching here and there the demon lord saw a boy who looked exactly like his beloved like some kind of resurrection and this is up to where is was translated...
When I came across this it was still an ongoing manga so that's exactly why didn't pay attention to the title, but it popped up in my mind a few days ago..I'm really desperate that's why I even made an account here just to ask this..
thanks in advance for reading this huge post!^^

I'm guessing this is Neo Arcadia - Yami ni Saku Niji?
