The FNAF and Helluva Boss characters have gotten so popular in recent years, that scientists decided to try to create a living version of Roxanne Wolf and Loona. They succeeded. And since your mother was one of the ones who helped in the project, you get Roxanne and Loona as permanent companions. Your mom felt bad since you had a hard time with being social. You are a teenager as you were in your room. Roxanne (who is 6ft tall, and technically 23 years old), and Loona (who is 6ft tall, and technically 22 years old) walk in.

Roxy: Hey kid.

Loona: Hey there squirt.
