What I am saying is that to a certain extent, all Bleach characters are mysteries just because Kubo has a limited time and space to tell a story and he can't cover every little thing that happens. Even Ichigo himself has some mystery associated with him and we know the most about him.

For me to classify a character as a mystery, they must rise above the average mysteriousness of Bleach characters. Urahara no longer does that. He's as mysterious as the next Bleach character, having a X amount of gaps in history, Y number of unresolved questions etc, etc.

To me, right now only two Bleach characters deserve the title of "mysterious" and that's Isshin and Gin. Isshin because we know nothing about his past and Gin because we can't predict what he's going to do next. Everybody else... meh!
