Disgrace
Ryu's expression was entirely indifferent. In fact, he had already retracted his blade as he took another step.
He didn't use his Spacetime Soul Nature for reasons only he was aware of. He was sharp and unbothered as a small soul appeared on his forehead. His, however, seemed to be completely counter to the delicate tea green of Emerald Vine's. His own was pitch black and exuded an aura as such.
Ryu vanished again and attacked once more. Emerald Vine was far more serious this time and was ready to counter as well. Her soul began to form hand seals again, but at this moment, Ryu mumbled something.
"[Lines of Fate]."
The world turned into black and white lines in his eyes, even the beautiful Emerald Vine becoming nothing more than a series of probabilities.
He focused on his soul, and in the eyes of everyone else, the moment Emerald Vine's soul began to form hand seals, his moved at the same time.
