The cover on the new raws shown that she's get beaten by Sulfur. But did she enjoy it?
She didn't.
While Sulfur is also a battle maniac sadist, she couldn't switch Azul's submissive and masochism side... so it could be because Utena who did it she became aroused maybeeeee? It could be also because she knew Tres Magia's identity, but she didn't know Utena's identity...
Also Whimsicat, how different is Utena's battle maniac with say, Sulfur or Leopard's battle maniac?
