Hideki Ide  

, 伊出英基

Soichiro has Hideki Ide as one of his police officers during the Kira Investigation. Initially, Ide departs from the team due to a disagreement with L's methods. However, he later re-joins and contributes minimally to the investigation. He assists in coordinating their efforts and executes tasks such as blocking off police vehicles to trap Higuchi. Following L's demise, Ide rejoins the probe, stating that his primary motivation was to be near Aizawa. Despite this, he holds a deep trust for Light, surpassing any other Task Force members except for Light's father.
