X-Men

After the death of his mother, Kamui returned to Tokyo after an absence of six years. Before the end of the world, seven seals (Celestial Dragon) and seven envoys (Earth Dragon) gathered in Tokyo to prepare for a final war that would determine the future of the earth. When "CLAMP" first debuted, it deliberately created a "CLAMP world" to make every work relevant and leave some "mysteries" in each work, which were intended to be revealed in the comic "X". The characters that appear in the "X" manga include "Menoyama Zan", "Ijuin Rei", "Takamura Sufang" from "CLAMP Academy Detective Team", "Emperor Subaru", "Emperor Hokuto" and "Sakurazuka Seishiro" from "Tokyo Babylon".
