Ties of Fate
Ryu felt that the full potential of all of his Bloodlines had been released.
If he had to describe it, it was like his body was a jar and his Bloodlines were the objects he had placed within it. Due to his Ice Jade Crystal Body, he was able to balance four Bloodlines almost perfectly, making the objects he placed within the 'jar' that was himself about the size of a finger nail.
However, even with the objects being so small, the air gaps were inevitable. In Ryu's opinions, his impurities, especially the toxic ones, had been hiding within these 'air' gaps, thus diminishing his overall strength and limiting how much power his Bloodlines could flood his body with.
The moment these impurities were gone, Ryu's Bloodlines fell into place like fine sand. Not only was there not the slightest air gap between them, but they had become absolutely perfect.
