Y'know what, I'm not gonna get mad at you for not explaining further. It was my fault for looking up that name in this context thinking that it was going to lead to some misunderstood Cassandra-esque figure.
For posterity's sake, if anyone here doesn't know who that is either but has heard of the infamous guro h-doujin "Mai-chan's Daily Life", well, that's Uziga Waita. And if you haven't heard of the doujin either, you should now have more than enough context to know whether to explore further anyway.
