Why Anbu?

How is it known that Taji is an ANBU? Is it stated in a databook? The one time we see her she is in medical garb... She couldn't have been chosen as a talented medic that specialises in maternity or something? (talk) 12:16, July 3, 2012 (UTC)

Hiruzen said that other than his wife, only ANBU would be there. Omnibender - Talk - Contributions 12:33, July 3, 2012 (UTC)
Thanks. :) I assume this is in the flashback episode in the anime (talk) 12:41, July 3, 2012 (UTC)
Flashback both in the manga and anime, after Naruto gains control of the Nine-Tails' chakra, when Kushina narrates how Naruto became a jinchūriki. Omnibender - Talk - Contributions 12:53, July 3, 2012 (UTC)
