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: Problem Children are Coming from Another World, aren't they? aka: Mondaiji Tachi Ga Isekai Kara Kuru Sou Desu Yo
Awesome Ego: Izayoi, the most arrogant and violent out of the main cast. but hey, anyone who makes defeating a water god look easy (at the end of the first episode none the less) definitely earned bragging rights.
He barely breaks a sweat when he completed a Gift Game in the Episode 4 in one night that according to Kurousagi would have taken years.
His inhuman strength. He made a crater by simply flicking a pebble.
Escapist Character: The titular problem children but especially Izayoi can be considered this - they are beautiful, smart, super strong and have awesome adventures, yet aren't annoying unlike many a Mary Sue character.
Fandom Rivalry: With No Game No Life due to their similar premise where the main characters are transported to another world and changes said world through games.
God-Mode Sue: Just about every battle Izayoi's been in usually has him deliver a Curb-Stomp Battle to whoever's facing him. If he seems to have any trouble, it's mostly because he seems to want to give them a Near Villain Victory right before utterly crushing them. This is not the case whenever he can't win by punching or is otherwise unable to use his arm, and has a hard time with Pest.
Values Dissonance: Black Rabbit is forced into wearing skimpy clothing by her employer and is constantly sexually harassed. This is Played for Laughs. No one could exactly help it either, since Shiroyasha is a goddess after all.
