Aizawa

Aizawa is an intelligent,respected member of both the NPA and Task Force. He takes his work very seriously and for this reason,does not approve of Misa Amane's antics. He becomes annoyed when she or someone else refers to her as Misa-Misa and he often chides Matsuda for his immature behavior. Aizawa's respect for L is grudging,as Aizawa chooses to work within the law and L's methods of investigation are sometimes outside of the law. After Light Yagami becomes leader of the Task Force,Aizawa is the first member to suspect that Light is Kira.

Problem with family:
Aizawa has a wife named Eriko and a daughter named Yumi. Aizawa and his wife also have a baby son whose name is not revealed. Halfway through the series,it is implied that Aizawa and his wife were having marital problems as a result of Aizawa's working on-call around the clock and rarely being home. Aizawa's daughter and wife both seem to miss him and Yumi is happy whenever he comes home. His wife Eriko,however,tends to take it in a more hostile manner. He is shown in a park where by chance he sees his family;he begins to cry while holding his daughter. It is unknown whether he and his family were able to mend,as they are not mentioned by Aizawa after the timeskip.
