The Emperor's Armor and the Empress's Armor were originally a pair of armors. The Sun God Runciman and the Moon Goddess Tarsiga were originally a loving couple in the universe, but due to conflicts caused by their respective families, the lovers parted ways. The God of the Universe gave Tarsiga a broken sword, which cut off the Emperor and the Empress, creating a pair of Emperor Armor and Empress Armor. Seven years after the Black Monster was eliminated, five armor summoners received news from Meizhen that the earth was about to face a disaster and there was something strange happening on the moon. Little did they know that the bloodline of the Empress Armor was with Xiang Yang in the Sunshine Welfare Institution, and was named "Tang Shui".
