Recruitment If thou art reading this, thou must have an interest in 'Slaying the Demon King.' Heh... Wilt thou join me in slaying the Demon King and protecting the world? Of course... the rewards shall be plentiful. Thou shalt have no regrets. I shall be waiting. -Assassin of Darkness-

Taking a deep breath, Guest knocks on the door.

Guest opens the door and steps inside.

Guest stares blankly at Seulgi.
Um... what?
