From One Piece to the Soul Society: The Strongest Shinigami

In the world of One Piece.

At the Summit War, Teach kneels on the execution platform and shouts to Newgate: "Old man, you're finally here! Save me!"

Nearby, Bane, possessing the power of darkness, watches the chaotic battlefield with interest and whispers: "Another hunt for abilities."

The New World's war for supremacy erupts, while in Fleet Admiral Sengoku's office, a Marine vice admiral reports to him: "Admiral Bane has gone mad! He says he wants to establish a new Marine! Zephyr-sensei has run off with him!"

In the world of Ninja.

Inside the Ryūchi Cave, Bane holds the Pink Dragon Fruit and says to the White Snake Sage: "If you serve me well, I will grant you the method to become a dragon."

In the Rain Village, under a heavy downpour, Bane looks at Pain of the Six Paths and asks softly: "Kid with the Rinnegan, what god do you want to be?"

In the Pure Land, the Shinigami flees in panic at the sight of him. It runs, he chases. In the end, the Pure Land loses its Shinigami but gains the Spirit Sovereign of Ryūchi Cave.

Harnessing the power of the Pure Land, he achieves supreme spiritual pressure.

In the world of Shinigami, upon first meeting Unohana, he uses the Chibaku Tensei technique to seal her.

Yamamoto Genryūsai is "all phenomena, reduced to ashes."

Then Bane is "above heaven and earth, alone I am honored!"

Even Aizen secretly thinks that the vacant throne is not yet something he can sit on.

"Yhwach, even Aizen Sōsuke and Yamamoto Genryūsai address me as Spirit Sovereign with respect. What identity do you have to stand before me?"
