Stefan (Shikai - "Rust & Shatter") wrote: The Sternritter were able to utilize the Bankai they stole from the captains, despite them having no Zanpakuto, by sealing the Bankai within their medallions. I believe Ginjo uses his Shinigami Combat Pass in a similar fashion. Before stabbing Ichigo, and stealing his Fullbring and other techniques, Ginjo attached his Combat Pass to his sword. I'm not sure that's what actually happened, though, it just makes sense to me is all.

Also, Ichigo was able to create, and utilize, Zangetsu, even though he had no Asauchi to work with, so there are ways around that obstacle. ^^

Ahhh I did forget those cases. But even then, you can justify those two:

The Sternritter are Quincy, whose core ability is to absorb and then utilize reishi. Even if unrelated to the medallions, after seeing the Sklaverei technique, it would seem pretty reasonable for them to be able to forcibly steal and then use bankai (and bankai only).

Then with Ichigo, he's just a super hybrid, with a bit of everything mixed in, that gains new powers as the plot demands. Not to mention he had Shinigami powers to begin with.

But with Ginjo, I can't see or make any connections as to how he attained a bankai. I mean it didn't even have a name and it seemingly just appeared from nowhere. Also in my opinion it looked (and functioned) more akin to a Resurreccion than to a bankai. As for the Combat Pass, what Shinigami powers were there to steal when Ginjo stabbed Ichigo ?
