Really off topic but has anyone noticed that Shigekuni has been the Head Captain since the beginning (over 1000 years) and in the Arrancar arc he mentions that the Ouken has been passed down from Head Captain to Head Captain by word of mouth for generations.. Kubo kinda messed that up but it makes more sense that Shigekuni is the only H-Captain and the Ouken's whereabouts have never been passed down.
