Before I start, I would like to say and ask one thing each:
1: I am up-to-date with the Manhwa series (webtoon).
2: (To the manhwa readers) Many of you guys gave bad reviews on the anime, but have you ever thought that there were no possible ending areas for the anime adaptation rather than at the end of the state tournament ending at around manhwa ep 112 somewhere? And with only 13 episodes licensed by Crunchyroll, they had to rush few things up. Or else the ending would've been major cliffhanger (similar to that of No Game No Life) and would've brought hatred also. The problem doesn't lie with the anime. The problem was, crunchyroll should've licensed 24 episodes to the anime (double cour or split-cour, as they like) so that things could've been made way more smooth which wouldn't have had brought about this undeserving hatred towards this anime.
Personally I liked the anime a lot. I mean, A LOT. True, some things might've been a little bit difficult to understand (because at that time I hadn't read the manhwa yet) but once I read the Manhwa, I could understand everything. The action and animation were so good and the character backstories were also super.
Easily received 10/10 from me.
