Promise of the Stars: Echoes of Time and Space

Lin Chen from the Stardust Exploration Bureau lost his memory due to the space-time storm three years ago, leaving only a pendant engraved with stardust patterns. During a mission, he reunited on the Ice Crystal Star with the silver-haired guardian Su Muqing who held the core of Stardust - the girl who appeared repeatedly in his dreams. As the stardust core resonates with the pendant, the broken memories are gradually pieced together: the two once made a stardust promise to "travel the galaxy", but were separated due to the core losing control. In order to protect the balance of the universe and awaken the power of stardust, Lin Chen, Su Muqing and their partner Chen Feng embarked on a journey in mechas to fight against dark forces such as the Lord of Nothingness and the Lord of Entropy, and unlock the ancient inheritance of the Star Vault Ruins. They used stardust as a contract and mecha as a shield to fulfill their agreement in the depths of the galaxy, fighting against the darkness with love and faith.
