....okay, old witch sensei didn't teach her enough. If she's willing to keep an eye on the little sister in a full magic academy, she absolutely should've invested some time parenting the older one.
I can't take the feeling out of me that this is Magical Ako ...
I guess is just the style, also reading KissXSis for literal years does not help.
But! i wish this manga gets at least some attention, i find this witches very cute!
