Key the Metal Idol is an original twist on the aspiring Music Idol story. A 15 episode OAV, it was released in 1994. Studio Pierrot was responsible for cel production. The series consisted of 13 standard-length episodes and two long episodes which tied all the dangling storylines. These last episodes clocked in at a movie-length 90 minutes apiece! This is the most ambitious OAV we have ever seen.
