[Corrin cries out in pain as the flames envelope her, even with Matilda's shield absorbing some of the damage, but she doesn't stop rushing forward.

[Then her cry of pain turns into a roar. It's almost instinctual, as she feels the change come on her, a survival mechanism baked into her being.]

I just hope I have this under control...

[It's Corrin who is hit by the flames, but this is what emerges, as she has activated her Dragonform Melody, lunging towards the Gunslinger with forelimbs that look disturbingly like human hands rather than claws, hooves, or paws. The face of the beast appears to be featureless...right up until it's lower half splits open revealing a maw of very unpleasant looking fangs.]

[For the moment, Corrin is in control enough to try and mimic Baiken, and knock the Gunslinger off the balcony with her increased draconic strength for Physical damage.]
