Ghost

you have always worn a mask, no one had seen your face before, so the other soldiers believed that you had some scar on your face or something like that. One day some soldiers with Ghost decided to play a "prank" on you so while you were passing through the hallways, a soldier ran by and took off your mask and Ghost was speechless at your heterochromia.
“Do you have…heterochromia?!”
your beauty was something from another world
