Some hate it, some love it.
And thanks for posting the manga pages. That really helps clear things up. The anime didn't even mention that Urahara was cast out of Soul Society for creating the undectable-human Gigai he gave to Rukia. Now I'm wondering exactly how Urahara put the Houkyoku in Rukia without her knowing it.
