Gaia Gear is a series of novels created and written by Yoshiyuki Tomino. Part of the Gundam metaseries, but not part of the canonical Gundam storyline, it was later adapted into a 26-episode radio drama. The character designer is Hiroyuki Kitazume, and the mechanical designer is Mamoru Ito (Yoshinori Sayama only for the pre-renovation Zorin Soul). Kenichi Onuki, Morifumi Naka, Masanori Nishii, Hideaki Anno and Yoshiyuki Sadamoto from GAINAX participated in the frontispiece drawing of the pocket books. Source: Wikipedia (en)
