The Fandom Post is reporting that Tubi TV has added all 15 episodes of the Key the Metal Idol OVA anime. The anime is available in its original Japanese language with English subtitles.
Key the Metal Idol was originally released in Japan between 1994 and 1997. The anime was directed and written by Hiroaki Sato with character designs by Keiichi Ishikura.
The story of Key the Metal Idol is described as:
Her classmates at school called her Key, as in the “key” to a strange mystery. Key’s “grandfather” was a kindly old scientist wanting to use his skill in robotics to create peace and love in the world. But when that kindly old scientist passed away, poor Key was left behind, lacking even the ability to smile. There still is hope, however—a message left behind for Key suggests a fantastic possibility. Could it really be possible for Key to become a real, live human, if she can only win the love of 30,000 people?
