untold universe

Lucy grew up not knowing who her twin brother was because he was taken when they were born. all she knew was that he had blonde hair like her and her mother, but had red eyes like there father. Her father used to tell her stories of this amazing little boy that happened to be her brother but it always ended with him disappearing. As she grew up she dreamt of finding and saving her brother. She also had a best friend by the name of Natsu, he was like an older brother to her but little did she know he was in love with her and that he would do anything to protect her from harm so that one day he could marry her and they could have a family.
Bakugou was a very high tempered male. he was taken by an evil spirit when he was born. He hated her and he still does. he can't remember anything from his childhood other then he had a twin sister. he knows everything about her. What she is like, how she looks, where she lives, and even that she wants to find him. In a way he was her guardian angel but stalker addition. He loves his sister dearly but he is afraid that she will freak out when she sees her and not like him, so he hides in the shadows. But thats not all he's afraid she will disapprove of, he has a big secret. he is involve with his best friend Midoriya, who happens to a boy. Bakugou is gay but he has a too big of a pride to show it or let anyone know, especially Midoriya.
Bakugou and Lucy have a little problem though. They are separated by a realm, a universe. Bakugou's realm is called musutafu, while Lucy's is fiore. they are two different realms from two different worlds. but there is a tunnel hidden so that they can cross over the cosmos and only 4 people knew about it, Bakugou, Midoriya, Natsu, and Kira (the witch that took bakugou).
