First I saw a very little picture, which had the Mami-san witch.
From there, I drew what you see here...
Then larger official pictures of the setting were confirmed, and when I noticed that in fact they more strongly resembled maids, I immediately prostrated myself like so... OTL
And so after all... I willingly kept to it in the initial setting~ (Not that I'm saying I dislike the maid costume look~)
