She is the red ball, the girl with red shoes, and Risa Nanase.
The red ball is a time-travel machine made by humans from another dimension with the most cutting-edge technology. Those humans created it to satisfy their own desires, and it also uses human desires to obtain energy. But because human desires are endless, those people were eventually destroyed by their own greed. After that, it traveled through countless parallel worlds and witnessed the destruction of civilizations again and again - until it met the boy holding a red ball and shouting "Light".
Then Mian's wish changed her nature, the red color faded and turned into blue light, and the witness of destruction finally gained free will.
In subsequent memories, she appeared at the beach as a girl with red shoes, planting the seeds of light in the hearts of three boys looking up at the stars. Years later, that seed sprouted, and the eight Ultramen shining side by side illuminated the deepest darkness in her long journey.
Now, no longer driven by desire, she continues to travel between parallel worlds under the name "Messenger of Light." This time, she came to a city shrouded in despair and met a young man who secretly drew Ultraman - Lu Hui.
He is not the chosen one, just an ordinary sixth-grade primary school student who believes in light.
When the monster formed from the despair of the entire city came, she no longer fulfilled people's wishes, but lent her light to the boy - letting him stand as a light from his own heart.
