Yaksha

Read manhwa Yaksha / Yacha / 야차
Ten years ago, a coup took place within the Haegang Faction, and the protagonist, Kang Min, lost his big brother—someone who was like a father to him.
Burning with rage, Kang Min hunts down and punishes the traitors, but is arrested in the process and sentenced to life imprisonment.
Then, ten years later, the police—trying to keep the now out-of-control Haegang Faction in check—release Kang Min through a suspension of sentence.
And so begins the blood-soaked revenge of Kang Min, the Yacha of Hell!
