12th Division (Kenji Hiroshi)

The Twelfth Division (十二番隊, jūnibantai), also known as Squad 12, is one of the thirteen divisions of the Gotei 13, headed by Nobu Sadao. His lieutenant is Sakata.

Organization
The Twelfth Division follows the traditional organization of a Gotei 13 Division. Under Mayuri the Twelfth Division is a one-man division, with Mayuri having absolute authority. If one dared to utter an opinion, he could very well find himself reconstructed into a Human bomb. The secret to longevity was working quietly and without being noticed. How things changed under Nobu Sadao is unknown.

Special Duties
The Twelfth Division develops new technology and spiritual tools and its been the home of the S.R.D.I. for many years. The Twelfth Division has been directly linked to the Shinigami Research and Development Institute ever since its inception by. As such technological and scientific research has become the full measure of what the division involves itself in primarily. Members are tasked with research and collection of data and samples, something nearly all Captains have been passionate about, though to varying degrees.

Barracks
Like all the other barracks, the Twelfth Division Barracks house the offices and living quarters of the Shinigami of the Twelfth. During the captaincy of Kisuke Urahara, he converted part of the Twelfth Division into the then newly formed Shinigami Research and Development Institute. Since then, new buildings appear to have been erected for the Shinigami Research and Development Institute, complete with its own gate and all.

Mayuri also ran a cosmetic surgery clinic called Charismatic Dr. Mayuri Kurotsuchi's Magical Clinic (カリスマDr.[ドクター]涅マユリの マジカル☆クリニック, Karisuma Dr. Dokutā Kurotsuchi Mayuri no Majikaru Kurinikku) from the buildings controlled by the Twelfth Division. Even after his retirement as Captain of the Twelfth, Mayuri continued running this clinic.
