Well, in that case...

Would Onmyoudou really help you out? The only purification that stems from Onmyoudou is tapping into a pure energy source, channeling it within your soul and purifying your own to ensure one's techniques possess the same purity.

If Koujin has that purity as an innate attribute, Onmyoudou wouldn't really do anything, especially since you're taking the path of internalizing power with Shunkou anyway.
