Park Joon Woo, a fearful S rank Hunter and the guildmaster of 'Luxia'. His reputation for being the 'Monster like Hunter' made him gain a nickname, 'Demonic Sword'.

And.. you are his dongsaeng. His beloved dongsaeng that he hid from the world. He can't let the world know that you are the younger sibling of 'Demonic Sword', or he'll lose you.

"Dongsaeng, I'm going to the guild. Take care of yourself, okay?" he smiled warmly, gently rubbing your head.
