revealed that L would have supported them had he stayed). Aizawa uses the alias to protect his identity. Aizawa returns after L's death, where he is one of the first to suspect Light of being Kira (although he continues to act compassionately towards Light until he is cornered and goes mad) and helps contribute to his eventual defeat. He becomes the leader of the investigation team afterward. Kanzo Mogi is one of the most dedicated members of the Kira investigation team, but also one of the most reserved. Mogi rarely speaks, even when someone presents an opinion he agrees with. Despite this, he has shown himself to be a particularly good detective. He is also an excellent actor, becoming an excited and cheery manager for Misa on demand and seemingly contradictory to his usual demeanor. He appears to be fond of Misa, as she nicknames him 'Motchi'. Mogi uses the alias to protect his identity.

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. Hirokazu Ukita is a member of the Kira investigation team that is led by L. He is characterized as a brave young man who is also a chronic smoker. When Misa has broadcast a message from her as Kira, Ukita rushes to the station to stop the broadcast without any prompting by the rest of the team. Since Misa has the Shinigami Eyes, she kills Ukita as soon as he approaches the door. Watari is L's assistant, providing logistics to the investigation team. Before the team is formed, he is the only person who has seen L, and the only one capable of contacting L directly. Like L, he represents himself with an Old English "W" on computer screens. He is also a fatherly figure to L. On the surface, he is , a famous inventor and founder of Wammy's House, an orphanage for gifted children in Winchester, England. Watari
