The series appears to be a sequel to the earlier SD Gundam Musha Maruden. Official relations were formed between Earth and the land of Ark. At an inter-racial school attended by humans and Mobile Citizens, young Ryuunosuke befriends fellow student Kokuryu. Life at the school can sometimes be fierce, with student gangs seeking to disrupt the harmony. But in the face of this, Kokuryu reveals a powerful ability- although he normally looks like a little kid, he can transform into the maturer samurai warrior Kokuryu Gundam. The series initially involves his battles against similar robotic creatures along with Gundam friends such as the bishōnen Hakuou Gundam and good natured/rough and ready Sekijishi Gundam. Eventually a mysterious group emerges, forcing Kokuryu and company to leave simple schoolyard scraps behind and engage in life or death combat. The general merchandising gimmick for this series involves the Gundam's being able to combine. This is similar to the gimmick for the series Transformers: Energon
