Imaginary Number Institute or Imaginary Number Research (虚数研 Kyosū-ken?) is a mysterious research organization that took in the young Accelerator to do research on him. It is apparently a hellish place, though even they could not handle Accelerator and his power.[1]
It is unknown if the Imaginary Number District is involved in their research.
