I think that Kurenai might just be the strongest one. I mean, he is basically FA/Devil/Dragon Hybrid, and he has the blood of Himejima, which might mean he can control that fire beast. And he is probably the smartest of them, then maybe he is kind of a strategist more than a front-line fighter?

But then again, he is also the oldest of them, and knows how to create Artificial SG/Longinus, so... we don't really know if he has one or not. Maybe he can even use Dragonification, or maybe even mastered it, for all we know.

But then again, it's my opinion. I might just be wrong and might just be right. Maybe we'll know, and maybe we won't.
