These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Villain Sue: Midousuji can come off as this. There is never a point where he suffers more then a temporary setback, his Hannibal Lectures always are extremely effective even when such chatter should be easily ignored, and he's able to outdo every character. It wouldn't be such a problem if he wasn't such a bastard, having no redeeming features whatsoever.
