“We should be going into a more peaceful era now.”
Yamamoto has dark, cheek-length hair and wears glasses.
He and Light's other friend from high school often discuss Kira with Light. The two of them gradually grow to become Kira supporters and believe that the deaths of criminals will be for the betterment of society.
Yamamato joins the Task Force within the year after Light dies. He and Matsuda are friends of a sort. According to Matsuda, they've gone drinking together, apparently more often than Yamamoto would like. Yamamoto also makes an appearance in the One-Shot Special.
