Well, plainly the butler did it, lol... every time he's around there's a black magic aura, and he is obviously controlling Selena-san.
Also, anybody notice the maid cringing in the background while the Harem debates their actions? Cos that seems significant, to me...
I wonder if the manga will be a bit different from the web novel version, because I remember from the WN that from this arc onward, the series sucks ball. I actually dropped the WN after this arc. Hopefully the manga will be better, but so far the details are the same so yeah...
@NoSoup omg same thought..... i don't find the chapter's art pleasing at all i don't even remember if the art changed but i remember the art not being of this quality in the beginning
