[I like Nirvana so much. If I write it casually, the timeline will deviate from the plot.
Fighting is strictly prohibited and proceed with caution. This is what the captain of the twelfth division wants from his daughter.
Becoming a complete Shinigami means dedication, and participating in battle means sacrifice. As long as anyone in the Soul Society exists, their honor and life have been tied to their loyalty to the Serenity Court.
He did not allow this illusory sense of honor to take Nemu's life. Living in the world, he lost his family; becoming the god of death, he lost his fiancée. If anyone dared to hurt Yinmeng, he would let that person taste the despair he had experienced.
After a thousand years of bloody battles, he made a child's body for Yinmeng. Watching Yinmeng grow and learn day by day, he experienced the joy of being a father again. But a letter from Urahara Kisuke broke this calmness. The letter read:
To the Captain of Division 12,
The store is facing bankruptcy due to poor management. I hope that as the director of the Technology Development Bureau, you can provide some assistance. Please be sure to bring some money and come to the store to get together on a certain day of the month. At that time, two lovely girls will take you to meet your old friends.
Nie doesn't know which of his old friends have not become experimental subjects. Urahara brought up that period of history that he didn't want to recall.
"Miss Linxi, she is still alive. Only you can bring her back," Urahara paused for a while, "After all, you are her fiancé."
Intention: After years of separation, Nirvana and Narcissus meet again a hundred years later.
