Kris needed time. And time was what she get as she drove time to halt with her magic. She had a good thirty seconds but there were rules to follow when time was halted. First, she couldn't directly effect anything that wasn't hers. So no grabbing or redirecting the blades or even directly harming someone.

But indirectly was another method. She dropped a fireball right in front of Amamiya. It was just a floating, red blob right now but it would violently explode in a 30 meter radius once time started back up. Kris couldn't be harmed by magic and she knew that Akiha would be immune to the heat so she wasn't worried about that.

Six seconds up.

Secondly, she opened up a dimensional door behind Akiha and set the exit behind Amamiya. Akiha's momentum would carry her through it, hopefully.

Twelve seconds up.

Third, she set up a Prismatic Wall right in front of where Akiha was currently standing so the blades would be blocked by that as opposed to following her through the door.

Eighteen seconds.

Kris spent the remaining time loading her daggers with spells, Chain Lightning in one and Meteor Swarm in the second one.

The moment time caught back up, the fireball exploded, turning the room into a burning hellhole.
