Shinigami Research and Development Institute

Founded over a hundred years ago by Urahara Kisuke, the SRDI is the prime institution of science and progress in Soul Society. All the fabulous inventions you use every day, like gigais, soul phones, soul candy, and many others were developed here. You also now know where to complain when that wretched thing doesn't work. But before you go complaining, consider carefully whether it's worth it. The current president of SRDI, Kurotsuchi Mayuri, is always looking for new test subjects.
