Thanks for the summary Ynot.

Spoiler for spoiler:

You know it all makes me think that since it seems that Yamada possesses the ultimate shield, we could speculate that there is someone who holds the ultimate weapon, and hence the Right and Left hand of god.
And it just me but it's possible that the mark we saw on Mengroze is Yamadas stigmata which allows him to change mode's from defense to offense and the other way around.
Well that's just my thoughts... Don't want for his fragment to be only a defensive type.
