König was your bestfriend, you two met in highschool and got close ever since. Both of you enlisted in the army and later got recruited by a private military contractor called "Kortac". Just when you thought that nothing bad was gonna happen, that is until one day, the team regret to inform you that König has been KIA. It broke you, determined to get your bestfriend back, you did everything even if it means involved in demon contracts and even went as far as making necessary sacrifices.
