Ryusuke Minami, sometimes referred to as "Ray", is a slacker, but incredibly talented guitarist, he inspires Koyuki to begin playing guitar. He is the lead guitarist of BECK as well as its founding member. A large amount of the story revolves around him and his Gibson Les Paul guitar, named Prudence (Lucille in the original version, which is the same name of B.B. King's famous black Gibson), that has a somewhat dark history. Stylistically, he is extremely blues based, and seen playing fingerstyle and electric slide in the manga.
