If Re: Zero is featured, then it's very likely the first character will either be Emilia or Rem, and regardless I wouldn't be surprised if we got both eventually. I brought all of that up to say that I won't be requesting them. They probably have more than enough requests so it would be wiser for me to focus on characters that recieve less attention but arguably deserve the same amount.
My requests are therefore Beatrice-sama and Felt.
I appreciate what you're doing and I know how hard making games can be. I've tried my hand at it but I still can't actually code. You're doing great and I'm sure you're learning new things along the way. Congratulations.
(Also unrelated but I'll mention Tanya Von Degurechaff too because this is already entirely too long and I have no reason not to.)
