This breakthrough had all begun with Ryu's attempt to claim a small piece of this nigh inifinite Infinity Mist for himself, so now that he felt that he could, how could he forget about taking advantage? Now, Ryu could finally clearly see through the distortion of the void, it was entirely unable to harm his comprehension in the slightest.
Ryu found that his eyes were even sharper now than they had been in the past. There was a nice positive feedback loop between his Bone Structure, his Soul Nature and his eyes. In fact, there was also the included benefit of the blood vessels running through his eyes as well.
Whenever Ryu pushed his eyes past their normal limits in the past, they would begin to bleed. This made quite a lot of sense as the blood vessels in the eyes also happened to be some of the most sensitive. But, now that his eyes had become maybe the sturdiest part of his body, it was highly unlikely for this to happen.
