Death: Not Dead? Then I'll Hug Aizen's Thigh Tightly.

Traveling through the world of Death, there is no system, no heaven-defying qualifications, and no bloodline bonus - Higashino Shuichi has practiced for a hundred years, and even the Shunpo principle can only be copied. Since you can't be a genius, then take refuge in genius. He took the initiative to find Aizen Sosuke and became the most loyal tool of this IQ ceiling man. Relying on his identity as the deputy captain of the Fourth Division, he secretly extracted the souls of wounded soldiers, and he had been doing this for more than sixty years. The Zanpakutō "Warrior" can decompose spirit children into villains and disperse them to sneak into position. When Aizen needs to figure out the layout of the noble hunting conference, he is responsible for the precise coordinates; when Aizen needs to harvest souls, he is responsible for attacking in the east and west. But here comes the problem - Unohana Retsu has already set his sights on him, Yamada Seinosuke is eyeing for the position, and Shifouin Yoruichi has witnessed his Bai Da and Shunpo, and is suspicious. And the new task Aizen gave him was to contact the broken bee. "I didn't die, but I have the strongest boss in Soul Society." This novel and its characters are purely fictitious.
