He still had no idea what they were, or why Martial Seniors had those, and no way of knowing yet. He knew that neither of the Martial Seniors was going to breathe a word to Rui, most likely.
('Although Senior Ceeran did let slip that the breakthrough to Martial Senior was a spontaneous event that could even occur in the middle of combat,') Rui recalled.
Perhaps that information was too trivial for Senior Ceeran to care to bother hiding. Furthermore, he was recounting his own breakthrough to the Senior Realm which had occurred in the middle of a battle according to him.
Regardless, when he glanced at the Martial Senior, things weren't looking too good. Senior Ceeran was having much greater difficulty than Senior K'Mala. He was not the type that was suited for the ODA system. In fact, Rui was sure that if he did end up adopting the ODA system in some new technique, he would probably use a portion of it.
And that was fine.
