The special Shrike may have been fast, but Fate was faster.

As soon as she saw it grab Nanoha, saw it start plummeting towards the ground, she summoned several magical orbs, shooting them out towards the Shrikes surrounding her. With her surroundings a little more clear, she shot off like a bullet towards the glowing Ohm, sword ready to strike. If she couldn't cut whatever was binding Nanoha, she'd just cut through the Shrike itself.

She already saw these things strike down Vivio. She was not going to let them hurt Nanoha, too.
