Check character for the girls in the back raising Erika, though I'm pretty sure the 4 girls in the front are who I think they are.
Also, I think the three girls between Emi and Nonna are yet to be named extras...? Correct me if I'm wrong.
P.S. Would it be more appropriate to add a spoiler tag for this? This is, after all, drawn as a post-match scene for the KMM vs Pravda match we see in the latest Das Finale episode, which I'm not sure all of us have seen yet even though it's already a year ago.
