Hideki Ide

Hideki Ide is one of the few police officers who remains with Soichiro during the Kira Investigation. He initially leaves when he disagrees with L's methods. Ide later returns and plays a relatively minor role in the Kira investigative team. He helps coordinate their efforts, and performs actions such as organizing a blockade of police cars to trap Higuchi. Later, after L's death, he rejoins the investigation, though he states that he only did so to be with Aizawa. Ide trusts Light more than any of the other Task Force members, except for Light's father.
