My roommates are fictional characters from a different dimension?!

Okay so this isn't a self insert.
This is about what yours truly. And I'm calling myself out here

Okays description
Lexa was a girl living with her grandparents for the time being, they were never home and she had to house to herself. But one day she hears a strange noise outside and hears her grandparents Dogs barking. With bat in hand she goes to see who out there...read to find out what she finds.

Update: so originally it was just going to be anime characters but now I kinda want to add video game characters. So yeah. Enjoy!

2 update: This is just going to be any fictional characters now! Because I was thinking and I was like. Man I really wanna add this character.
