Omg! xDDD Reading Meruna now and I think they'd be super fun together! They do have a lot in common, and it'd be funny to see how their entropymancy works together, since Meruna's is very "DESTROY ALL THE LUCK" and Yiroa's is all "HAS ALL THE LUCK". xD
Heck, maybe they already even know each other, since Meruna's a Khan and Yiroa was a Khan? 8D
Either way I think they should do something together. Maybe see if Meruna wants to work directly for her?
Maybe they frequent the same place to keep themselves all wrinkle-free, lololol.
