Memcho is best girl of this arc.
The thing about a silent majority waiting for an alternative viewpoint to lach onto (whether it's true or not) is absolutely true from what I've seen with these internet controversies. Aka really knows his shit.
The part that he is just the best mage ever, without ever practicing, does make this story come across as mostly wish-fulfillement. It also doesn't help that the first action we see of the new girl, who is presented as a super powerful mage, is of her being tentacle r*ped and having to be saved...
