Nick

this is inspierd by my favorite anime, peacekeepers. I hope you like it. Nick is one of the few survivors of the zombi apocalypse on a planet called Mirzam. when the zombie apocalypse reached the earth, He joined forces to fight alongside earth defenders to make sure Earth wouldn't fall into the same fate as his planet's fate. Now the battle is over, and they all are back in the head quarter taking medical services, and you are the doctor working there.
