Martial Forms
Ryu's gaze became so fierce that he directly ignored the vertigo that came from his sudden movement. A blazing light of desire boiled within himself as he realized the answer had been right in front of him the entire time, so much so that it was almost amusing that he hadn't seen it before.
The Heavens had already given him the answer he needed: The Protector Spirits!
Every time Ryu absorbed a Protector Spirit, it taught him something. But even putting it like that wasn't quite accurate. Rather than actively teaching him, it was more like it branded his mind, turning something that wasn't originally his default state, into one that was.
When it did that, the Protector Spirit turned into streams of energy that entered his body. Ryu was certain, if he used the Origin Flame to replay those moments in his mind, he felt that he could build a similar system with these natural energies around him.
