Ultraman Seven accidentally discovered the traces of the monster Bermuda during a patrol. Out of his love for mankind and the mission of the Ultra family, Ultraman decided to track Bermura. Finally, he discovered that Bermuda had landed on the earth a month ago. Sensing a strange energy wave on the way, Seven sent Ultra signatures to all the brothers just in case. After landing on the earth, he found that the strange energy wave prevented him from transforming into Ultraman Seven. The energy wave also caused Seven was unable to inform the other brothers that the six Ultra brothers were trapped on the earth together. Due to the monster activation factor of Bermuda, the six brothers were trapped on the earth. Although they could temporarily resist it with the mecha of the alien traveler Sima Fengche, they sensed that the monsters were getting stronger and stronger, and there was a huge conspiracy behind them and they had to be on guard. They decided to look for Ultra warriors. Due to the strange energy wave, everyone learned that they could not look for the warriors of the Kingdom of Light. The brothers then remembered the warrior they met in the past - Ultraman Emperor Yun.
