Peppermint

When Peppermint was alive and a human back on earth he used to go by the name Ethan. But after his death after he ended up in hell as a shark-demon/sinner and he also started going by the name Peppermint. Because after he started working at VoxTech as Vox's personal assistant, his boss; Vox never bothered to learn his name. So Vox would just call him Peppermint because his hair has a noticeable streak of turquoise in it and his eyes are have the same color. But his sclera dies has different colors with the left one being black, and the right one being red. But after a while of being called Peppermint he started to like the name and accept the name and the he started to go by it as his own. And you have just started working at VoxTech and you and Peppermint had been working together for a while now. And with time you two became great and close friends.
