Cassiel seemed content to have reigned supreme in this moment. Even so, she wasn't unfamiliar with the things the Red Dragon Emperor was experiencing. Even as they were healed, it seemed that he was struggling with something within himself and Cassie observed this with a knowing light within her eyes. Sariel observed it with something much closer to fear, the last time this particular dragon had rampaged, he'd rather easily dispatched a fallen angel and would have taken out a large chunk of the city without the help of almost a dozen other devils, and various creatures of lore working together. Right now, she didn't much like her chances with just herself and Cassiel as the only thing standing between this lad and the kind of destruction he could reign down upon them. Even if Cassiel were capable in this moment of doing something great about him, with their current exchange of abilities, in their Juggernaut Drives their battle would be closer to fair than the last time, and that would be the sort of battle which could wipe this whole town off the map. Whatever the case, these fears were not realized. Either by the mark on his hand, or his own will, he overcame those voices at least once, and didn't finish the incantation which would have started the pair of them onto another epic battle. The bit of tension that had built up in the angel, was let out in an exasperated sigh. "Whew, I thought I was about to be in trouble for a second there. I am glad, she managed something..." she said without much detail on the point, but seeming to understand the lad had been reigned in at least a little by his master. "I am Sariel, the Angel of Mercy and also the Guardian Angel of Cassiel, it is nice to properly meet you, Yasukawa Takumi..." she said, already being privy to the name which the boy had and among other things choosing to be polite in this moment.
Regardless of this, Cassiel had one piece of advice for the lad, which likely would let him know at the very least, even though she was already past this point, she understood what he was going through. "Yasukawa-kun, if you are truly the Dragon of Domination... make sure your voice is the loudest. Drown out the others with that will of yours," she said giving the lad a curt nod. "Arigatou na..." she said turning to walk away now. She had plenty more to think about and all of it surrounded the strange events which seemed to constantly take place around this boy. Meanwhile the angel who'd landed with them so recently simply nodded her head. "I am sure that is all she has to say. Thank you... for keeping her company. She may not show it well but, she appreciates it," she said acting as emotional speaker for the girl who seemed to be a bit of an anomaly as she was fine with abandoning this fight having given the lad the only advice she knew could help him.
