We did Suletta, so it makes sense to do Miorine. I can't be the only one who thinks that these two are like the Gundam Universe's version of Ruby and Weiss. Like come on...
Miorine is the rich "princess" with daddy issues, white hair and she's a massive Tsundere. What is Weiss? A rich Heiress with daddy issues, white hair and a massive Tsundere.
Suletta is the socially awkward, innocent bundle of joy but is a complete badass in a fight and doesn't give up hope with red hair. What is Ruby? A socially awkward, innocent bundle of joy but is a complete badass in a fight and doesn't give up hope with reddish hair. (At least not until Volume 9)
Suletta has the balance of a nice rack and cake. Miorine has A slightly smaller rack but does have nice cake.
Once again, just like Ruby and Weiss.
