If Yachiru really is his bankai then I wonder why he "found" her as well as his sword in rukongai. This and the "sword-has-a-soul" questions are my biggest worry. Tbh I wouldn't be surprised if Kubo leaves the reasoning as "Zaraki is a special case and so he/his sword don't follow the rules".

For the materialization aspect (given that Yachiru even is a materialization) it might just be part of Zaraki's zanpakuto ability because Yachiru's shikai had a sort of materialization aspect too; if she can't get slice something/someone then one of her shikai creatures are able to and the creatures were a materialization as well. Moreover, like with Muramasa, I'm pretty sure that sword spirits can reside outside as long as the sword isn't in shikai or bankai state- which is why, when Zaraki used his shikai, Yachiru seemed to have disapperaed.

To be quite honest, Zaraki hasn't, well, ever been the "control" type of person. Perhaps he, like Ichigo with some of his "transformations", might just charge into a battle without honing all parts of his newly found bankai. Oh, and Yachiru (if she really is his zanpakuto's spirit) might not have told Zaraki about his sword's capabilities because she a) might not have believed he was ready to know, like how Renji and his zanpakuto were or b) wanted to respect Zaraki's wishes to stay as is cuz he didn't really seem to be all too motivated or ambitious to obtain an even higher power prior to the Quincy attack.

Btw, I though Ichigo's dual blades aren't Zangetsu (as in the old man lookin dude) but rather a materialized representation of his soul......WAAITTTTAMINUTE DID WE EVER EVEN GET A NAME FOR THIS NEW STATE??? =.= But yea, I'm pretty sure Kubo is gonna pull a Zanpakuto-ex-machina and have Zaraki's bankai be wayyyyyy too OP but then have it seem meh~ again for other opponents (who may be stronger yet than this Thor-like dude). Also, I've no clue what you were trying to relate with the White Ichigo thingy...?
