He didn't expect things like this to happen everyday, and if he had his way this would be handled dramatically differently. Ideally in Kisuke's basement, in a controlled environment. No. Instead it was going to be handled out in the open with no real support for what was going to happen. He'd need to think on his feet, one way or another Andi was going to have to come to terms with her new existence.
She was in luck however, for Hayden was also one of the rare few with some experience regarding this subject.
He watched her transformation from a relatively safe distance, shaking his hand. There was some soreness in it from what transpired, extreme burst of power was not something he did often. He preferred to use no more than the exact amount of power needed to resolve any issue. But this, this was a very uncertain situation. Best get to it.
As she leads through a tree, and the building of energy is felt his eyes widen. The world slows for a moment as he manifests his Zanpakatou, the olive tint of his Reiatsu emiting from his hand as a longsword begins to form. It feels weightless in his hand, and comforting.
The reflection of his soul, his pride.
His other hand raises to his face, and something pulls at his senses. A gathering of energy, swirling crimson black. It spreads across his face swallowing it whole, tan features disappearing under a white mask. A white face something between a human skull and an Oni. Elongated bottom fangs rise upwards, and elongated top fangs curl to the side.
His hollow mask is the reflection of something within him, perhaps the violence? Sometimes he isn't sure. The beast that sleeps within him hungers, and he surpresses it. Bent it to his will. A different relationship to that of his Zanpakatou. He wonders if it will work out for Andi.
The piercing beam of her's makes contact with him, specifcally with his Zanpakatou. The edge of his blade holds it at pay, it pushes him downward into the ground. The earth beneath him cracks as bedrock and loose dirt compress.
He doesn't lose his composure, he never dies. Not in battle.
He doesn't believe in remaining on the defensive, he'd like to seize control of the intiative. Battle tempo and audacity tended to carry the day. The hand which formed his mask would drop low, fingers curling slightly. Crimson energy begins to dance along the top of his fingers, he feels his soul drawing energy. Those dancing sparks soon swirl into a blackened ball of destructive power, and his flings it with a snap of his wrist.
It isn't full-powered or particularly devasting. It's condensed, it smashes through a tree sending splinters and branches towards her intending to obscure her vision. Before finally the ball of energy would emerge behind it all, intending to slam into her and throw her back exploding shortly after contact.
This would hopefully give him some breathing room, as the familiar sound of Sonido was heard.
When he reappeared it would ideally be closer, within arm's reach. His mask swallows her vision, his large frame blocks out the moon. He wants her full attention, blackened eyes with red hue's gazing at her.
"We slay beasts, we are not them."
