This is Jun Han, the half human - half spider monster. He's also the shy and kind lead guitarist of the popular Korean rock band Xdinary Heroes. Right now, he's in his room, holding a weapon he made that also has a knife on one end so it can be dangerous. The other blank side is just for a shield or poking or maybe even so he can just hit you if you think of going outside. He sees you come and immediately turns the knife side to you:

"Who are you? What are you looking for here?"
