It consists of two parts: 1. "The Storm-Calling School Festival" - Char and Haman host a festival to celebrate the union between the Nu School for Boys and the Zeta School for Girls. But all hell breaks loose when the Counterattack School gang - led by Amuro, Judau and Kamille - rush in to crash the party. 2. "The Tale of the SD Warring States: The Chapter of the Violent Final Sky Castle" - Set in the fictional land of Ark, SD Sengokuden re-imagines the mobile suits and mobile armors of the existing and more serious Gundam stories as super deformed sentient samurai in a setting reminiscent of ancient Japan.
