To be fair, the Anima she's challenging doesn't seem all that opposed to a quick scuffle. The puppy-sized black dragon is still doing his best to puff himself up, fan his wings to look better... and generally get his 'YOU WANT SOME!?'presence going. He even does a growl, though coming from a tiny dragon it sounds very warble-y at best.

The scion standing nearby, meanwhile? Is doing his best not to bury his face in his palm.

"...Think nothing of it," Oswald replies. "It seems unlikely that any damage was due to happen."

Whether that's an idle boast for his own Anima, or lack of esteem for either of the creatures is anyone's guess. At least he follows it up with another statement. "Both seem willing enough to enter into a fight."
