So does that bond system work for any ninja variations? I mean if bond with Naruto is increased will the bond level for Sage Naruto also increase.

I am asking because I highly doubt that any of the Rare/meta Ninjas will be available for this bond system, and I think it might be available only for the basic ninjas. Can anybody give any insight to this?

Wow everybody's already talking about Konan even though she won't be available in the shops until mid-April. :)
