Sometimes i wonder if Ex and Airi are actually the strongest among the children. I know Shin said they are the strongest but it feels like we never actually got to know what the other siblings are truly capable of. Ishibumi seem to only gave us a basic introduction of their powers for the others.

Did Shirayuki or Kurobara even fight? And didn't Kurenai like only fought in 1 chapter on-screen or script? Then there's Elmenhilde's daughter, Ernestine, who did like almost nothing.
