Shinigami Research and Development Institute

The Shinigami Research and Development Institute is an organisation within the Shinigami. It is behind the development of many of the Technologies that aid the Shinigami, and is currently headed by Mayuri Kurotsuchi. It was founded by Kisuke Urahara, during the time when he and the Vizard were captains.

The Shinigami Research and Development Institute has performed extensive research into the modification of souls; the results of this research were artificial souls, both in the form of "soul candy" and Project Spearhead. The SRDI also tracks spirit activity in the real world, maintains gigais, and developed Kenpachi Zaraki's reiatsu-absorbing eyepatch.

The SRDI was not involved with Ran'Tao's creation of the Bount, its establishment postdating the Bount's creation by some centuries.

The SRDI has close ties with the Twelfth Division of the Gotei 13 and both presidents of the Institute have also served as captains of that division.
