Tenchi Muyo!Tenchi Muyo! (天地無用!, Tenchi Muyō!), is an anime, light novel, and manga series created by Masaki Kajishima and Hiroki Hayashi about a boy named Tenchi Masaki, which has grown into a larger franchise. Tenchi Muyo! was one of the early successes for AIC, the animation company behind it, which went on to create El-Hazard, Battle Athletes, Oh My Goddess!, Dual! Parallel Trouble Adventure and many other anime series.
The original series, Tenchi Muyo! Ryo-Ohki, is a six episode Original Video Animation (OVA) released in Japan in 1992–93. As its popularity grew, it spurred a seventh episode (also known as the Tenchi Special) and a stand-alone Mihoshi Special. In 1994-95, the second OVA series (episodes 8-13) was released, featuring episodes 8–13. A third OVA series (episodes 14–19) was released from 2003-2005, followed by a special twentieth episode.
