Suguru Shimura

Suguru Shimura (卓志村, Shimura Suguru) is the Head of Personnel in Yotsuba. He is a very paranoid person, and always keeps a close eye on others. Shimura's ability to pay attention to small details allowed him to join the meetings; he noticed subtle changes in Namikawa's face during his phone call with Light, who was pretending to be L.
