Everything about the manga begins with the world of Lelouch

The world consciousness once shattered the entire world to cut off the causal connection between the two parties because it was completely disappointed with the travelers in its own world. After meeting several funny dead people, he met Bo Yu and asked him to make a choice after discovering the unexpected harmony of his souls. But Bo Yu did not let her down and chose to help her. Later, with the help of Lelouch's world consciousness, they helped Bo Yu to be reborn, so they treated Bo Yu like a child. Bo Yu also regarded her and Bo Hua as mothers. After receiving treatment, she chose to create a miniature and chose the same appearance as Bo Hua, but she was more mature than the noisy Bo Hua.

In the world"Titanfall" it belongs to, technology has completely reached interstellar colonization. At the same time, Bo Yu was provided with Titan information and resources, and Bo Yu's car was replaced by AI-1 through the influence of world consciousness. (Although this was strongly protested by Ji You) However, due to world rules, interstellar ships can only appear after the world is sublimated. But he has already started to help Bo Yu build a sky battleship.

He gave Seruberia a bottle of medicine that could turn Bo Yu into a weak person. (Since Bo Yu is a child of the world, the system that was once an ordinary person has completely exploded after growing up.) Seluberia used this bottle of medicine to successfully win Bo Yu's first blood with Cornelia.
