SD Gundam World Sangoku Soketsuden (SDガンダムワールド 三国創傑伝) is a Japanese media project by Sunrise and Bandai Spirits and a reboot of the BB Senshi Sangokuden franchise, based on the long-running Gundam media franchise.[1] Created to celebrate the 40th anniversary of Gundam,[2] it is also loosely based on the 14th century Chinese historical novel Romance of the Three Kingdoms by Luo Guanzhong. However, Sangoku Soketsuden is different from BB Senshi Sangokuden in its theming and story. It is later succeeded by SD Gundam World Heroes.
An original net anime adaptation by Sunrise premiered online from July 26, 2019 to March 25, 2021. Two print side stories by Takuya Yamanaka were announced to be released in their respective magazines.
