Firstly we have my favorite princess, Rosalina

There are an infinite number of Galaxies so her pulling up to help out our boy Subaru isn't too far fetched.

Next up we have Rem, we already know how this turns out so not much explanation on her.

Emilia, of course. He won't fall for her when they first meet. That stuff is gonna take time.

Shaula. Subaru is her master, there's nothing much to say about that. Annnnnnnnd, she is one of my favorite characters in Re:zero so....🤷🏾‍♂️

And finally...Elsa

I'm a lil...uh..."iffy" when it comes to her. So I'll leave it to you guys. You guys want Elsa to be a part of this or nah?
