The supplemental stories and hints were that Unohana was the best kendo practitioner in the Gotei 13. This should be interesting if she gets drill sergeant style on Kenpachi. This will also lead to dozens of Kenpachi/Unohana fanfics. Can't wait for the summaries:
"Unohana and Kenpachi have a very rigorous training session. While taking a post-exercise dip in the Squad 4 spa, Kenpachi starts to notice how attractive she is. R/R and leave comments! THX!
