He is the primary protagonist of Sakura Taisen 5 and the Sakura Taisen New York OVAs, and nephew of Ichiro Ogami. A young Navy lieutenant from Japan who becomes the captain of the New York Combat Revue. He is hardworking and dedicated to the samurai spirit, but is somewhat straightforward, which leads to problems. Compared to his uncle, he's easier to tease mainly due to his age, innocence and inexperience (especially with women). Shinjiro loves and honors his mother and frequently sends letters to her. He is talented physically and academically, and addresses every problem wholeheartedly. Shinjiro's mother is a caring woman who is a master swordsman and is very motherly, though she tends to go a bit overboard and teases Shinjiro just as much as the others do. After an incident involving a duel with Subaru, which he lost, he was forced to perform on stage as a girl named Petitmint (Peppermint in English). They often force him into the costume in the OVA having him perform Cleopatra.
