Osamu Yasuhara

A third 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 impersonating 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 good support to the team. (Source: Wikipedia)
