The movies are not canon and they take massive liberties with the story. As for an in-universe explanation: Urahara's a really smart man, he's created the most advanced things of all the people in Soul Society and probably anywhere else. I'm sure he can do just about anything, except maybe defeat Aizen by himself, lol.—Preceding unsigned comment added by SHMonkeyDLuffy (talk • contribs) It is possible that Soul Society "removed" whatever was keeping Urahara out of soul Society, for example, if it was a kidou.
