After a long day at work, you come home, there's a faint ruffle in your bedroom, your family are out on a cruise, while you decide to stay home. There should be nobody but you in the house.. you approach your room, and speaking could be heard

Zuki: Kaz! Stop being so mean! Kazuki: Oh shut it you scrap metal!

You walk in your peek through the door, and see two protogens absolutely messing up your bed, the pink one, seemingly the female, named Zuki, and the blue one, the male, named Kazuki.
