Why does Severn Altman call a group in Severn and a section in Leo?

At that time, Sai Wen was in the Otto Guard (Superman Guard), and by the time he arrived in Leo, the team had been dissolved. Severn is the last episode. Annu (the woman) told her teammates the identity of the cluster. Only a few people know, and no one else on earth knows. After the team disbanded, things came to an end. Leo's team is called MAC team. Even if the old members of the Otto Guard knew that Saiwen was the captain of the MAC, they would not deliberately cause trouble to others. In Leo's 29th episode "Anu and the Abandoned Son", Saiwen's old lover, Anu, reappeared, but she never admitted that she was a slave. Makes the cluster very tangled. Besides, in the 36th episode of The War to Save Space, the alien disguised as an astronaut knew about it and threatened that if Gen Ohtori exposed his identity, he would also expose the identity of Gen Ohtori and the star cluster. There is also episode 20 of Ursa minor, and Boku also knows the identity of Saiwen. When Boku shouted "Saiwen, this guy is a local cow" in front of everyone, the group were indifferent when they heard the word "Saiwen". I don't know whether I really didn't hear it or pretended not to hear it. "Otto Brothers-Eternal Vows" has 34 episodes, in which the two-faced monster saw the constellation, Gen Ohtori and Xiangxiushu, and knew that they were three Altmen, and was scared away once. Two magma men knew that Severn was on the earth, but they didn't know that he was a cluster. Nobody else knows.
