Oh, my God... Who are these girls? I mean, I know where they are from, but I want to really know who they aaaaaaaaaaare! They are so cute.
They're from the new Madoka game, Magia Records. More information on the wiki, but let's just say this, Mitama (blue) is the shopkeeper (and also someone who can actually mess with the soulgem to "fix" magical girl's stats). Momoko is a playable character. They seem to be close, due to the fact that Mitama can't cook (yes she CAN'T), Momoko often comes around to cook for her so yeah, there's that. Mitama is kind of a pervert btw... (literally asked the main character to strip)
Also fun fact. The original sound effect on the original pic is actually written as follow: "もみ もみ", "momi momi", which is a sound effect, but also stands for Mo(momko)Mi(tama). Pretty sure this is not coincidence.
