Scaling Acqua to Kanzaki

Kanzaki spun her body and turned her head around, slicing the water wing behind her with one slash. Seeing this, three water wings of the messenger of God attacked from the air, each with a slight time interval between them. Even though there was a time interval, the difference was measured by a hundredth of a second. An ordinary person couldn’t really sense that somewhat godlike speed. A human needed 0.18 seconds to process the command from the brain to the fingers, but Kanzaki, as the Breaker of God, and could enter superhuman territory for a fixed duration, thus such logic didn’t apply to her. Her blood vessels, muscles, nerves, organs and bones were all greatly enhanced by that technique. ZAN! The first water wing of the trio was slashed by Kanzaki’s Battojutsu. Before the next hundredth of a second arrived, Kanzaki had already sheathed the Shichiten Shichitou and prepared for the next attack.

She could already predict the moment she would no longer be able to match Acqua’s impossible speed and suffer the finishing blow. For Kanzaki, who already struggled to keep up, it was impossible to make a comeback and go on the counter-offensive.
