Detective Shirase was initially in charge of the IS-7 investigation, until being replaced by Tyrell Badd after a disagreement with the lead prosecutor for the case, Manfred von Karma. However, after Badd cooperated with the defendant's defense attorney Gregory Edgeworth and realized that the victim's autopsy report was falsified, Shirase was brought back to replace Tyrell as a witness for the subsequent trial. After Edgeworth proved that evidence had been falsified in court, von Karma received the only penalty in his "perfect" record. However, it was Shirase that took the brunt of the blame and was soon fired.

Note
Wataru Shirase is unique in that he is the only character in the Ace Attorney series to date to be given a full name, but not have any sort of image to show what he looks like.
