This post is about Matsuda from Deathnote. Matsuda is a member of the Task Force, and helps L with the Kira case. He is naive in some ways, but he really does try his best. He also tries to prove himself by taking matters into his own hands. It did end up putting him in trouble, but his actions did get the necessary information for the Task Force. He also has a kind personality, but can be stern when he has to be.
