Silva

It seems that Hao Asakura and Silva have the same vocal actor.

But the fact is that Hao Asakura + Silva and Kaoru Sakurayashiki have the same vocal actor.

It would be a comparison/resemblance between the two,namely between the great onmyoji Asakura Hao and Kenjaku.

Hao during his early life, he lived under the uncertainty of the corrupt and careless Heian nobility, who led the country into chaos and poverty. He saw the world as a gloomy, dark place.

Kenjaku is an ancient sorcerer who pursues the goal of "evolving" mankind through cursed energy, ushering in a new golden age of jujutsu witchcraft, parallel to the Heian era.

Heian (平安) means "peace" in Japanese. Although it was not so despite the meaning of his name.

Although Kenjaku uses a technique to transfer the brain to control that person while gaining the skills and techniques of the person that Kenjaku has mastered. Unlike Hao who has reincarnated over the centuries.

This is the first appearance of Kenjaku in the manga, namely Noritoshi Kamo.

This is Hao Asakura's first manga appearance.

This is Kenjaku's second manga appearance, namely Jin Itadori's wife.

This would be Hao Asakura's second appearance as an evil version of Silva.

Silva being a positive character and is represented as a kind of judge/referee.

This is Kenjaku's third manga appearance, Suguru Geto.

This is Hao Asakura's third manga appearance.

In any case,neither in the case of Kenjaku but also in the case of Hao Asakura, it is not known exactly how many appearances/reincarnations the two had.

But Hao Asakura's ideal had been to destroy both weak shamans and all mankind.

And I think Kenjaku's ideal would be in a way similar to Hao Asakura's because Kenjaku is the one who organized the sacrifice games.

In the sense that Kenjaku wants to eliminate jujutsu wizards who are weak but also people he calls monkeys.
