Aoba loves to make model robots. However, she is taken to a secret base where she discovers a new mecha, designed to fight the Ancient Jinki.
In early 2007, the series was dropped from the pages of its publisher, Mag Garden, for many reasons, one of which was Tsunashima disagreeing with the editor-in-chief of Monthly Comic Blade regarding the mecha of the manga.1 The series eventually restarted in the Dengeki Moeoh magazine published by MediaWorks.2
An anime television series adaptation animated by Feel aired from January to March 2005. The 13th episode never aired on television and was released as an OVA. This title was picked up in North America by ADV Films for $91,000,3 who released the series in three volumes and box set. However, in 2008, the title along with over thirty other ADV titles were transferred to Funimation.4
Giga would go on to create multiple adult games in the franchise on PC, complete with art by Tsunashima himself. They include 2010's Jinki Extend Re:Vision, a retelling of the Extend manga, 2020's Jinki Resurrection, a sequel to the Extend manga's Complete Edition, and 2022's Jinki Unlimited.
