Hyun-Su Cha

The main character of the story. An isolated, lonely teenager who is forced to move when his family dies in a traffic accident. He is eighteen years old and stopped going to high school due to unknown reasons. He spends his time trolling and tricking on internet, as well as playing various RPGs. He sold his old house and moved into Green Home apartments (room 1410) because the money left by his deceased family was insufficient for him to survive as an isolated person. He then proceeds to chose October 25th as a date to commit suicide.

His weapon of choice is a handmade electric spear, powered by a large battery that he carries in his backpack.
