Shuuichi Aizawa

Serving as a highly intelligent and respected investigator for both the NPA and the Task Force, this dedicated officer operates strictly within legal boundaries. He is known for being the most skeptical member of the group, frequently clashing with L by questioning the detective's methods and conclusions. While a devoted family man to his wife, Eriko, and two children, his intense focus on the Kira investigation has caused significant strain on his domestic life and relationships.
