One Piece: Kaido's adopted son, starts with the Eight Gates Formation.

As her braids came undone, her gentle and kind demeanor faded rapidly, almost unnoticed.

Instead, there was a cold, sharp killing intent that seemed capable of freezing one's soul completely!

An immense and terrifying spiritual pressure, so immense it was suffocating, suddenly erupted from her seemingly frail body!

That spiritual pressure was filled with an aura of blood and slaughter, as if it were an Asura emerging from a mountain of corpses and a sea of ​​blood!

All the captains present, including Byakuya Kuchiki, felt their breath catch in their throats.

This spiritual pressure...

So familiar!

It's both good and...unfamiliar!

The Captain Unohana they remembered was always gentle and strong, but never like this, filled with a chilling, pure bloodlust!

"Captain...Unohana?"

The vice-captain, Kotetsu Isane, who was closest to her, was so frightened by her captain's cold and unfamiliar profile that she could not even speak clearly.

Unohana Retsu ignored her.

She simply untied her captain's haori, revealing the standard shihaka outfit underneath.

Then, she slowly raised her head.

Her gaze did not fall upon the invincible demon child, Lynn.

They didn't even bother to look at the powerful invaders.

Instead, it traversed the entire battlefield and pinpointed with unparalleled precision the ruins in the distance.

The man who had just been defeated by Whitebeard in one move, but who stood up again because of the Captain-Commander's defeat, his eyes rekindling his fighting spirit.

Kenpachi Zaraki, captain of the 11th Division.

"Did you hear that?"

Unohana Retsu's voice was cold yet carried a strange, almost sigh-like pleasure.

"The sinner's...roar."

As she finished speaking, a hideous and ancient huge scar was exposed to everyone's sight below her neck and collarbone!

That scar seemed to be silently telling a bloody story that had been buried for thousands of years!

The moment Kenpachi Zaraki saw that scar, his heart, which beat only for battle, suddenly clenched!

A long-forgotten pain and...excitement, buried deep in his memory and almost forgotten even by himself, surged wildly from the depths of his soul!

It's him!

No, it's her!

When he was just a wild child in Rukongai, he was the first to let him experience the joy of "fighting", the first to leave a scar on his body, and also the first "prey" to be defeated by him!

"It's you..."

Kenpachi Zaraki let out a beast-like growl, and a smile that was more insane and excited than ever before appeared on his ferocious face!

"Hahaha...hahahahahaha!!"

He threw his head back and laughed wildly, his laughter filled with the ecstatic joy of finding his nemesis!

He finally remembered!

This woman was the strongest rival he had been searching for all his life!

"It seems you haven't forgotten."

Retsu Unohana slowly drew her Zanpakuto, the one named "Ninjazuki," which possessed terrifying healing abilities. At this moment, however, the blade emitted a chilling, ominous blood-red light.

"Then let's relive that battle from back then."

She didn't look at Lynn, nor did she pay attention to the shocked gazes around her. Instead, she issued her final challenge to Kenpachi Zaraki.

"Come on, Kenpachi Zaraki."

"Let us fight to the death here for the name 'Kenpachi'."
