He is a 3rd year top-ranked high school student and president of his school's student council. Yasuhara first appears as a client of SPR as a result of unexplainable phenomena occurring at his school. After the case is solved, he continues to help out SPR on other cases, including standing in as "Kazuya Shibuya" at the request of Naru and performing background research off-site while the others are on a case. He has no psychic powers of his own, but his sharp mind and work efficiency make him a great help to the team. In the anime television series, Osamu Yasuhara is voiced by Kousuke Okano in Japanese and Eric Vale in English.
