Well introduction to the story sounds pretty standard. Children with super powers fighting monsters while adults are cheering them up from the safe spots. But as we learned in anime that is not a bad thing. Stories based on that cliche can be amazing and entertaining.
And at the beginning QC does not look bad. It has world with not that many plot holes.
We meet world with three cities or rather three schools that defend their world. HOWEVER these schools does not matter. Only difference between them is how their uniforms look like. And fact that in one school students fly on brooms, second has swordsman type fighters and last one is for marksmen. But that doesn't matter, students are just background for the few main characters and it is very poor background.
We meet the world with ranking system which was never fully explained. Of course we instantly know that it is based on combat strength of students. It was opportunity to show some struggle going up, rivalry between students. But nope, instead we get... well nothing. One guy who is proud of being #4 and that's all. One guy who is below top 200 and he doesn't care. Awesome use it, show how strong he is despite his low rank. Nope nothing. We met probably two strongest students but that does not matter at all.
The plot is not complicated and after at most 3 eps you will be expecting the twist. Don't get me wrong. Story is written quite nicely, it is interesting and what is most important - I enjoyed it despite being so straight. I wasn't overjoyed with it but it was decent.
Powers called 'worlds' seemed to be important to the plot. I admit idea of gaining one as the result of dreams is not bad. Child dream about world, gain power based on that world (probably, they never explain it properly) and get supernatural ability called 'world'. And that's all. They are not interesting. Girl unleashing power with her sword made one or two big 'booms', boy controlling gravity never used it in interesting way. Sniper and her sister who is gunner showed few interesting actions but to be fair we never grasped how this marksman's ability worked at all.
But characters. They were very POORLY designed. I just finished this anime and I can't remember single character's name. But let's give main cast at least some thought and why they were... not the worst but not good either.
Chigusa siblings - awkward brother and sister with bond that you will feel while watching them interact. But also I felt very awkward watching them. And I loved Ore no Imouto so I believe I can even accept anime when you put line 'incest ftw'. Their social awkwardness and weird interaction between them was both interesting and creepy. I guess Kasumi was meant to be the smart guy in this anime as well as caring guy who shows it being asshole but it didn't go well. He was just... creepy.
Ichiya Suzaku aka #4. At start he is guy who is full of himself and believes that he can handle everything alone. Of course we discover he acts that way so he can protect the girl he loves (what a shocker!). And he starts to change into a little bit more cooperative guy (and more tsundere guy yack!) after accident. Then we see him go berserk after he loses the reason to live, which is understandable but it is again not showed properly so we can't feel bad for him. Instead he was at the beginning annoying asshole, then annoying wimp. Of course he was written to be opposite to Kasumi but that didn't work well.
His supposed reason for living and fighting wasn't written better at all. Canaria Utara has little to no personality and quirk of being a slouch (is this proper word? the moments when I feel my english sux ;) ).
Maihime Tanekawa was the #1 student who also believed in protecting everybody. Great she didn't left any impression on me!
And last but not least Hotaru who was Maihime's friend and something like her guardian angel. They tried to show how strong their bond was but I just couldn't feel it. It was obvious what author intended to write but he did poor job.
But side characters do not add poor impression. Why? There is almost no supporting cast. Few guys even more forgettable.
Art and sound seems fine. Wasn't great, but ok. Few nice songs, decent graphics, fights wasn't impressive but didn't look terrible too.
Bottom line it is not bad anime it won't make you bleed from eyes or ears but if you don't have much time I suggest to skip that one. You wont miss anything at all. I bet in two weeks I will forget about it.
