As one of the newest memebers to STN-J, the Japanese branch of the secretive organization known as SOLOMON, Haruto is your typical clumsy, stubborn, yet honest rookie of the team. He's a rather brash character who doesn't always think before he acts, yet his intentions are always for the better good. As a result, he often gets injured, and frequently comes across near-death expereinces. At the same time, he's a fairly warm character who hold no judgment against his other team members.
