After Inuyasha's work is completed, the world begins to reincarnate.
Sesshomaru fought in endless reincarnations, until in a certain reincarnation, his arm was cut off by Inuyasha again, and his consciousness fell into the abyss of chaos. When he was dissociated, he glimpsed the false nature of the world, and understood that the world he was in was just an animation work. At the same time, as a bystander in the depths of his consciousness, he "saw" the real world where Xia Yuan lived, and everything strange and vivid made him curious.
But as "Half-Demon Yashahime" started airing, his inexplicable taboo feelings for Suzu left him in pain and confusion. In order to deliberately divert this forbidden emotion, he tried to devote all his attention to Xia Yuan, whom he had paid attention to before. Unexpectedly, during his deep spiritual exploration, he unexpectedly broke into Xia Yuan's conscious (spiritual) world. After spending three years together day and night, the two gradually fell in love.
However, the more Sesshomaru fell in love with Xia Yuan, the more he realized the cruelty of reality. His world is filled with monster battles and fateful duels, and as an ordinary person in the real world, Xia Yuan cannot be safely protected behind him. It can only be done through dimensions and cannot provide substantial help. This feeling of powerlessness was like a huge stone weighing on his heart. In the end, he chose to leave Xia Yuan's conscious world and let her be free.
Xia Yuan's resolute departure from Sesshomaru caused a shadow, believing that everything in the conscious world was just his fantasy, and even mental illness, implying that he had never been in love. And Sesshomaru didn't believe that Xia Yuan would travel to his world.
Unexpectedly, two years later, when Xia Yuan reviewed "InuYasha", she broke into his world, and her soul awakened in Princess Sara's body, continuing the unfinished bond.
