The plot of the series revolves around Gundam, a member of the Earth Federation Forces who gets into various instances of trouble with almost everyone around him. One of the central points of his trouble is his rivalry with Char, a pink ball who wears various Char Custom MS as clothing. The cast list and story grows from that point on. The manga's structure is standard to yonkoma, with several (mostly) related four-panel strips sandwiched between an overarching plot.
