The Career of a Shinigami Starting from Hueco Mundo

After his death, Natsuki came to the world after death. When he opened his eyes, he saw a vast desert and a pale moon hanging in the sky. Afterwards, another monster all in white attacked him. Just when Xia Mu thought he was going to die, a figure dressed in black and holding a long knife appeared and killed the monster. Everything is developing in a good direction. Unexpectedly, a bigger monster appeared, and before he could ask the name of the man who saved him, he died. In order to survive, Xia Mu could only pick up the long knife left by the man and choose to fight. He didn't know that when he held this knife, he had already become the god of death! … From Hueco Mundo to Soul Society, from the Expeditionary Force to the Gotei 13. This is Natsuki's death career! (Note: Hueco Mundo is just the initial spawn point, it won't last long, and it will soon enter Soul Society.) (Note 2: The protagonist has only watched the animation, so he only knows the plots that appeared in the animation and those original TV plots, but does not know the plots of the official novels)
