Pros: The story itself is intriguing and brings new flavor to the fighting genre (for most of the part). The animation is really good. The 1v1 tournament fight scenes are beautifully animated and extremely pleasing the watch. The main characters have depth and growth with some good character building. The opening is just AMAZING and the music in-between the fight scenes is really good and appropriate. The Japanese voice actors also do a really good job in portraying their character's emotions.

Cons: While the story starts of as intriguing, it is too rushed with a lot of unanswered questions remaining in the end (90 chapters worth of the webtoon have been fitted into these 13 episodes which results in a lot of missing pieces). A lot of the side characters are hyped when they're introduced but seem to vanish the next moment. Moreover, the story shifts from a tournament arc to a fanstasy story, which isn't a bad thing, but seemed to abrupt.

In conclusion, the anime has a lot of potential and over time, could easily become a masterpiece. The shift in story, while abrupt, is interesting, and I'm sure a lot of unanswered questions will be answered in the coming seasons (hopefully). All in all, this is a must watch anime.
