Even if Rui had made predictive models for all of the Martial Squires ahead of time, he could not know which Martial Squire was being deployed when the K'ulnen Tribe's Martial Apprentice inevitably failed, ahead of time. That was why Kane had been deployed outside of the K'ulnen village, waiting to identify which of the Martial Squires of the K'ulnen Tribe had been dispatched against the Martial Apprentices of the Martial Union to protect the K'ulnen Martial Apprentices.
He was to immediately inform Rui of which of the Martial Artists had been deployed via a pre-decided code since they did not know the names of all of the Martial Squires of the K'ulnen Tribe.
Code H was a low-grade Martial Squire, lower than Rui but not by much.
