Rui had limited himself to defense to explore the limits of his new technique, while familiarizing himself with how the technique felt in different counters.

He had half-dodged the attack before it had begun after it was too late for Kane to change his decision.
This was not the most optimal counter to Kane's maneuver according to the adaptive evolution model. But that was fine. His intention was to grow familiar with using Godspeed to move before his opponents moved after it was too late to change their decision. His normal speed meant that against something of the Root's caliber, even if he did begin moving ahead of time after it was too late to change the attack, he would be too slow to make it in time.
('But with this… I think I can-Hm?') Rui's attention returned back to Kane who was tired of being toyed with, taking a crouching stance.
