Notice the tunnel effect, colors and how Ghislaine effects when she kills the guys. Reminds you of absurd speeds in other anime like Goku's and others.

Tough a little different there's a program out there showing what you see from the world and how it gets distorted as you approach lightspeed (in fact causality speed, but doesn't matter here)

As Munsu said, we know nothing of Ghislaine stats.
