Holy shit. I thought this was just going to be a nice wish-fulfillment power fantasy, but damn, chapter 15 hits hard.
Edit: Just finished binge reading this series and I can confirm it is an exceptional series. It takes all the tropes of the weak to strong hunter in Korean manhwa and capitalizes on them fully. Can't say there is much unique about this series, but it will make you laugh, it will make you cry, and it will certainly get you pumped as you see it's well thought out and well-exicuted action sequences. Definitely deserves the 9/10 it currently has!
