Ranking of Kings is an anime about a story of a little prince named Bojji who is cursed with deafness and stripped of any strength. Yet he still powers through his difficulties.
The art style may seem childish, but it gets dark real quickly.
However, what's best about this anime is that it breaks from other anime trope and nothing is at it presents to you at first and truly represent the idiom "Don't judge a book by its cover".
A recommended watch for sure.
I've watched the Ranking of the Kings. Definitely didn't think I was going to end up liking it as much as I did. For anyone out there I would definitely recommend it. It's not your classic anime. But it's definitely the one of the most interesting animes I watched.
