Oshihito Katsuragi (葛城 忍人, Katsuragi Oshihito, literally "Oshihito of Katsuragi") is one of the main characters in Harukanaru Toki no Naka de 4. He is technically the first Genbu of Earth (地の玄武, Chi no Genbu) of the series. His memories are used to bestow a human trait into the Genbu of Earth dragon gem, thus influencing the Eight Guardians in later generations of the franchise. His particular trait is "Wish" (願い, negai). In Otome Game of the Year 2008, he was ninth place in their favorite character category.
