Guh, Akiha was getting out of control. There was only one method she knew would have even a slight effect but she hadn't tested it either. And it took quite a bit of concentration from the alchemist. With the situation as it was, she couldn't risk doing much else.

So Sion focused and, thankfully, it worked. Her right arm half-transformed into the bottom half of the staff. She didn't want to hurt Akiha, only knock some sense into her. Which she tried doing by bringing it down on Akiha's head with carefully calculated force.
