He is the guitarist of Blast; attended the same high school as Nana Osaki. He is friendly and optimistic, but at times, he tends to miss the focus of conversations around him. Before Nana's "smoking ban", he's the only non-smoking member of Blast. But, his poor threshold for alcohol meant that he leaked many secrets while he's drunk (most notably, about Nana and Ren's relationship to Shin). Like Yasushi, Nobu comes from a rich family (his parents own an inn). Despite this, he is still very passionate about music, even sharing Osaki's dream of making it big with a band one day.
