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.
Anti-Climax Boss: For as much as they're made a big deal of the White Kampfer tend to go down pretty easily.
Moral Event Horizon: The Moderators as a whole cross this with the revelation that defeated Kampfers are turned into Unpersons, meaning Kaede had already crossed the MEH just by her affiliation with the Moderators even before said affiliation was revealed at the end of episode 10.
Snark Bait: Natsuru's stupidity made this series as painful as getting teeth pulled without anesthesia. Even so, that didn't stop many of us from watching it each and every week, did it?
Also, the fact that the entire plot is one big Clingy Jealous Girl fight (with the occasional Manipulative Bastard Shizuku moment) got about as predictable as the morning sun. Hell, even the minor characters are only interested in getting Natsuru naked.
