Hisashi Imakurusu

A doctor who personally denied approval for the Murai vaccine was himself in the final stages of the cyberbrain disease, and was being kept alive using the Murai vaccine he himself worked to keep from the public-along with countless other well-known public servants. Imakurusu had dedicated his life to finding a cure for cyberbrain sclerosis, only to have Murai usurp him unexpectedly. Although Imakurusu had privately felt that he would have approved the vaccine if Murai had been able to discover why it worked, the Laughing Man believed that the dual motivations of greed and jealousy led him to suppress the vaccine. The existence of a custom-crafted ‘approval denied’ stamp would lead one to agree with him.
