Айдзава Шюїчі

Aizawa is an intelligent, respected member of both the NPA and Task Force. He takes his work very seriously and chooses to work strictly within the law. Out of all the members in the Task Force, Aizawa is the most overtly skeptical, questioning L's basis for his conclusions and expressing the most doubt in them, and often finds himself clashing and opposing many of L's ideas and actions. He has a wife, Eriko, and two children, including Yumi, his daughter, and his baby son, whose name is unknown.

Due to him rarely being able to visit home during his work on the Kira case, his personal life and relationship with his family becomes strained.
