Thanks for the insane work, Silas! It's always a joy to discover a manga to binge and a pain to reach the end and wait for updates, but you extended that nice period with those mass translation.
It sucks that the fun is over now, but this manga is surprisingly solid, so even individual chapters at a time I think would be more than enough to keep the interest in this.
It's a very silly and horny story, but it's still full of sense. Like this hierarchy of demons now, and why this invasion is not as apocalyptic as it seemed at first. That's something we could see right at the start: Hell seemed an alright place, and demons just another species in that diverse world. The problems come from barely evolved monsters and unfortunately here, those at the top that are crafty and malevolent.
Though, I got that the Fox lady is playing both sides so that she comes out on top, but then I'm not sure what to make of Oasis? Was she just a red herring for the true traitor, or was that just to say that the top of Heltiera has a shady side, hurting people so much that here it led to someone targeted by it, a Demon Eye girl, to betray everyone?
Finallly the Demon Queen can't die. She belongs in the harem, that's the rule
