User blog:Dangai Train/Yhwach's backstory

I hope that when Yhwach is finally defeated that Kubo will reveal his back story and the events that led up to the first Shimigami-Quincy War. I'm curious to see if he and Yamamoto were always at odds with each other from the moment they met, or if they started out as friends/allies with a common goal until their strong idealologies drove them apart and ultimitely into open conflict with eachother, sort of like the relationship between Proffessor Xavier and Magneto from the X-Men comics. It would be even better if it went into some detail of what Unohana's bankai actually does.
