Named After Ultraman

Traveling through multiple worlds and saving people from fire and water, he is neither evil nor righteous. While he saves people, he also longs for redemption. He does not try to warm others. He believes that instead of convincing others, it is better to rely on his own actual actions. He doesn't have any armor on him, and he doesn't have too many forms. He just keeps learning and learning other people's moves. His name is Saiyan, he was once a scientist, now he is a warrior. He has no story of his own. He said: "I don't have many stories. I only have one or two past events about you. You ask me, what is my story? Your name is my story." He embraced Eren's cold body, he wiped away Mikoto's tears, he embraced Artoria in his arms, and blocked thousands of troops for her. He stood in front of the Ten-Tails, and the coalition forces behind him looked at him with trust. For his own sake... This novel and its characters are purely fictitious.
