I know everyone says “join the harem” but I wonder how much we believe this ends in a harem. I honestly would be a little disappointed if it did. #Amelie4Life
It's not a matter of 'believing', seeing as statistically speaking, this will end without Iruma ever dating anyone. Second on the list is him dating one girl, but probably not Amelie. Possibly that girl that he saved from Asmodeus in the very first chapter...she was the first to fall in love with him.
Harem endings in harem manga are extremely, absurdly rare.
Which is why...yes, I hope it WILL end with a harem ending. Because I am honestly fed up with harem stories building said harem literally the entire time, only to give a completely and utterly illogical turn at the end.
Look at ToLove Ru. Lala wants Rito to have harem. Her sisters want to be part of that harem. Haruna is fine with the harem. The law of the planet of which Rito would become prince if he married Lala allows harems. He loves more than one girl. But yet...the story ended with Rito literally still conflicted on actually starting a proper relationship (although he DID do things that count as dates, to my memory...for a change), let alone accept that idea which literally is to everyones benefit, his own included.
