Manhwa is just like Manga, a comic. But, it comes from Korea. The names and culture are usually a little different but believe me, there are some amazing titles to go through.
The Breaker is a series that I will always remember to be my entry into the Manhwa world and it was just awesome from the get go. The sheer volume of characters and badass moments as the MC develops in the world of a hidden martial arts world was an instant hit for me.
If you're into martial arts stories, The Breaker is right up there with the best. With 2 seasons out, we have long since been awaiting a new set of volumes to start. Sadly that's all there is for now and perhaps that is all we will ever get. But it's totally worth the journey until the end.
