well, they do make it sound like they had to go through a similar process to ichigo to control their powers, so who knows? if I ever meet Tite Kubo, I intend to ask him.
Yes, that's right, but the thing is that Ichigo's hollow is mostly just metaphorical really. What happens in Ichigo's inner world shouldn't be taken literarily because it wouldn't be as interesting writing to just see Ichigo meditate or whatever which is essentially what he was doing with Jinzen for example.
screw your demon foxes, I have Hichigo. because he's the only guy in the show who will always stand on par with Ichigo. for obvious reasons. plus I LOVE his Japanese voice. thankyou for making this and reminding me of the Hichigo awesomes :3
