Commission for Nero Carpio.
Gabriel (the green haired megane danshi) and Zadkiel (the SS officer cosplayer) are her original characters. The theme here is simple, just Gabriel teasing on Zadkiel… by calling him a Nazi. Which is a bit confusing, since Zadkiel is actually dressed as one. Meh, who knows, it is a request after all 😛
I apologize in advance for the nazi swastika here, it’s just cosplay.
