Heh, a nice chapter, I like the fact that the pace is decent. Plus the blushing Jin-woo is amazingly silly XD
The (I assume ) russian hunter is amazing. I like him, but he's most likely going to die when the gate breaks open and then one way or another Jin-woo will come and save the day.
... incidentally, I really like the design of the japanese S-class female hunter. She's drawn just the way I like, both in casual clothes and in a suit. But this is a manwha, and the korean-japanese animosity is always present, so the japanese hunters are most likely all going to die.
