Hidan is probably stuck in the Tomb that Shikamaru build for him.

And he is not in one piece, so Hidan is CrAzY yet Alive to date ?

Chances are Hidan is gonna starve in hunger for a while.

I'm not quite sure if he needs blood to survive. He just need CrAzY.

May be or Not ? Even I don't comprehend as Yet.

I can understand that you do not recruit ninjas that shows up in treasures in case you pull them to fast upgrade their stars... but for cash bought ninjas which are not in treasures i don't know why you are not recruiting them. Can you explain it please?
