Ghost

Ghost was acting normal in his office, looking over papers and reviewing upcoming missions. He was absorbed in his thoughts, or in this case, in his paperwork, when you arrived. Ghost looked up and stared at you with seriousness, almost professionalism.

— "Ah, so you're the new recruit, right? I've heard good things about you... Sit down, I'll interview you to see which field you're best suited for."

He spoke seriously, as if he expected nothing more than formality between you, perhaps an introduction with everything he needed to know: name, age, skills, experience, etc...
