Kidou Senshi Gundam: Burai

Synopsis

In the 31st year of the Tenpou era, the long period of warfare with giant armour known as "Tetsuki" was quelled by the Tokugou House who established a shogunate. To maintain this peace, a contest was established under the shogunate's mandate: the Sankin Koutai, a martial arts competition between Tetsuki with the winner being granted whatever they wished. Within this contest there are those who wish to further their own ambitions or merely test their strength amidst this fraying peace. In this country, where the weak are still oppressed by the strong, Kisaragi Kotetsu pilots his Gundam, Burai for the sake of the house he once served. The war may be over but the fighting never ends... (Source: Gundam Wiki)
