About Shin SD Gundam Gaiden: Gaitoshin Senki

The series introduces the concept of a human-type character that transforms into a Gundam-based form. (Something later reused in another series, New World Advent Legend) The character designs in the series are taken from mostly Mobile Suit Gundam Wing, including the G-UNIT sidestory. The series went only up to three chapters originally, with the fourth chapter being released with the complete box set in 2010.
