^^ @FrankieX98 only if the Female Malebranche looks like Grayfia ^^

Euclid has a bad little possesive nature with woman that look like her (Rossweisse ...cough)

Oh because we are talking about it...did you noted that Katarea Leviathan did not used water based attacks against Azazel. I mean in the Anime it looks a little like dark Water shaped Snakes, but I think it has never been said that it was Water...

Seems the decendants of the Maou in the Old Maou Faction were never fully trained in there Bloodline Ability (exception seems Shalba, but even he did not used it to his full Potential), or they were simply weak in comparison.
