User blog comment:CoolJazzman/Soken Ishida death caused by Yhwach?/@comment-4458023-20130626212428

I think its an interesting theory, but if you recall, Yhwach stole the powers of impure quincy, such as half-bloods and corrupted quincies. Soken was a pure blood quincy and wouldn't have been tampered with. Thats my theory.
