The "story" pretty much fell apart the moment the MC found an actual solution to his problem, but rejected it, because "he wants to find a way to gain mana on his own".
I know this is absurdly shounen, with over-the-top positive characters; but that's just unnecessarily dumb. The author wrote himself into a dead-end by reaching the precise goal the MC was gunning for too early, and then had to shoot it down for a non-reason in order to keep the story going.
I wouldn't even class that as "parody", that's just stupid. And not the good kind.
