Shunichi is one of Riho Yamazaki's old friends from high school. Unbeknownst to her, he loves her. His major hobby is film making, which he, Riho, and friend Mikako used to do a lot before Riho became a dhampire. He's very sweet and aloof, thinking that Riho's sudden personality changes and absence from school have to do with drugs, thus trying to find out exactly what brought about this change.
