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.
YMMV: The Law Of Ueki
Angst? What Angst?: if Ueki's team loses the third round, they'll die. Nobody cares about this little fact. Everybody just sees to forget about that lottery in the second round.
Karlpaccho, not only is he lecherous, but but injected Sano's God candidate with a boy sucking parasite in order to force him to join the Robert's Ten, and later mocks him when he sacrifices himself.
Crowning Music of Awesome: The anime soundtrack seems to be loaded with several completely awesome songs. Case in point: "Battle of Abilities". Someone just pulled a thoroughly epic turnaround on their opponent? There's a song to go with it.
High Octane Nightmare Fuel: Anon can take the form and powers of any being... after he swallows them whole.
Also, his introduction is him attempting to do really horrifying things while being completely unaware of why it's wrong.
Also, Robert Haydn.
And even he was swallowed by Anon.
The Scrappy: Several fans seem to find Mori Ai terribly annoying.
