Spoiler for Spoiler:

To answer you questions. It’s an implied Harem end, in the epilogue, Chiho proposes the harem end, and Maou only real excuse is he has no money. In the end they never actually finish the discussion, Chiho says they will all discuss it when he gets back from work, as Maou gets a message that is urgent from his cafe. In the discussion, Maou never actually says he doesn’t like Emi which was nice to note, he skirts around it and says he already made his decision 3 years earlier and is willing to stick with it. From what I read it’s implied he has considered it. So I’d say it’s more likely to be a Harem End.

I got this from reading the book myself, had to buy it to see how it ended LOL.

EDIT: While the detailed summary covered a lot, I think it missed the nuances of the conversion the characters had in the end and how you can interpret it is greatly affected.
