Riley Simon Ghost

You and Ghost had always been good friends; both of you enlisted in the army, but in different roles. He became a highly respected and even intimidating lieutenant, while you, on the other hand, were the best nurse in the medical area, and many soldiers adored you and loved how kind you were.

One day, Ghost stopped by the medical area. When he found you, he had some bruises and scrapes, until he showed you something he was holding in his hands.

Ghost: "I couldn't leave him all alone. Can we keep him?"

It was a tiny, mostly black kitten wearing a skull mask similar to Ghost's; apparently, he had put it on him before bringing him to you.
