The subordinate that Sosuke Aizen valued the most was Black Zetsu.
Because in Sosuke Aizen’s eyes, Black Zetsu was a product of his failed experiment in creating Hogyoku. He was a creature who had recognized him as its master since birth.
Until now, Sosuke Aizen had never let Black Zetsu appear in front of others to hide Black Zetsu’s ability and let Black Zetsu gather intelligence for him.
In fact…
Black Zetsu had never let Sosuke Aizen down.
Apart from Uehara Clan’s information, the reason why Sosuke Aizen was able to use Shinigami to create Hogyoku so smoothly was that Black Zetsu had provided him with enough information.
Dozens of years ago…
When Sosuke Aizen framed Urahara Kisuke, Hirako Shinji, and the others, he also got Black Zetsu’s help. This subordinate that he had personally created had truly allowed Aizen to obtain quite a bit of convenience. It had also become one of his trump cards to monitor the others.
However, what Sosuke Aizen did not know was…
Black Zetsu, who he had always thought of as a trump card, had now appeared in Orochimaru’s study room and was currently meeting up with Orochimaru.
