I am one of the countless Ultramans from the Land of Light, a red civilian Ultraman. There is nothing particularly outstanding about me. I don't even have a name. My codename is just my name. My codename is 521. I have always had a dream, which is to protect the earth like my predecessors! But I didn't dare to act without orders. One day, I was chatting with an Ultraman codenamed 99. I told him my dream, but he laughed at me and said that I didn't have that ability. Even if I went to the earth, I wouldn't be able to protect the safety there. This completely ignited Self-esteem, so I made up my mind to go to Earth and prove it to Ultraman codenamed 99. I secretly left the Kingdom of Light and traveled through the universe. I came to an Earth that was being invaded by monsters. I will definitely protect this planet like my predecessors!
