Isabella watched the man move back and talk about the territories and this being his town, she wasn't really paying to much attention to his speech, before long it'd become noticeable that her wings stopped shimmering, becoming more bold in appearance, as if taking up a harder tune to it, the edges no longer looking pointed but flat and curved, multiple layers in the appearance. In all respect, she still looked like she didn't have a weapon on her, which would be strange, all angelic warriors had weapons visible, even other Seraphims, she just looked un-armed, save for the strange looking cross necklace upon her.
She knew he had some power to him, all to familiar power, it wasn't the first time she fought or seen beings like him, demi-gods. "Earth is my domain to protect now. Since you will not leave..." She started to say, cutting herself off as she simply unleashed a sudden kinetic blast of dark energy from the left flank of her opponent, it wasn't terribly strong of a blast, considering she had no charge to it at all, but at the same time she maneuvered her wings around her front, crouching down, within seconds after the blast went off on the small blast, sending pure black smoke around and a slight ear piercing like noise, enough to confuse most people with the sound and distort hearing flow, within the crouched position she took off the cross into her hand, beginning the change of energy in order to transform it into a weapon.
