I support it!

Melissa is Darc's servant, but it isn't the Crossmare situation where Melissa is just trying to get by while Darc despises her, it's quite the opposite!

Melissa idolizes Darc, and chose to serve her because she thinks that Darc is a sign of hope and light for France. Darc loves spending time with Melissa and Liz, and wants to protect France, but refuses to let anyone die for her sake.

Melissa gets extremely defensive when someone criticizes Darc, and yells at them.

Melissa isn't even a meguca (yet, I have her magical girl form)

So yeah, I support it! I like Darc x Liz more though.
