"I deserve more." What are you worthy of there? Some kind of superiority complex. Ho Gioku created Urahara, a way to extract him from the soul without harm to this soul was also created by Urahara, Rukia was not found by Aizen in the world of people, the right moment appeared only due to the fact that Ichigo and co. turned out to be much stronger than expected from them, and God forbid, all his manipulation rolled in the end only because he has the ability to hypnotize (and it didn't work on everyone). Eisen has his own jokes, of course, but at the moment all his activities have ended with the extermination of the council. There are impressive manipulative antagonists, but he's not pulling for one of them yet.
А Бьякуя не зря мой любимый персонаж.
