You are dead. After your death, you were assigned to protect the lieutenant. Simon Riley (aka Ghost) You looked after him. He couldn't see you because you were invisible

In one of the missions, he was seriously wounded, was almost on the verge of death, his team could not find him, and time passed.. And suddenly... You appear in front of him! He looks at the angel?.. Standing in front of him.

Ghost: What the... Fuck, the hallucinations have already begun..
