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

The Fourth Blade, Ulquiorra Cifer.

First Blade, Koyatai Stark.

The Third Blade, Tia Harribel.

When they stepped out of the dark chamber and saw the scene of the Seireitei below, even Ulquiorra, known for his indifference, showed a slight ripple in his usually calm green eyes.

What... is going on?

Seireitei has been taken down?

Why are those monsters with two horns on their heads and those Grim Reapers in black kimonos cleaning together?

Who is that guy sitting at the very top who looks like an ordinary human child?

Why is it that even the immortal old man, Yamamoto Genryusai, has collapsed to the side, ignored by everyone?

The absurd scene before them was momentarily overwhelming for their minds, which were accustomed to killing and conquest.

"It seems something unexpected has happened here."

Stark yawned and said lazily.

"I must report to Lord Barragán immediately."

Ulquiorra said expressionlessly, his eyes having used some kind of ability to simultaneously transmit everything below back to the Royal Palace in Hueco Mundo.

……

The virtual circle, the virtual night palace.

On that huge and empty royal palace made of white sand.

A withered skeleton, wearing a crown, sat quietly on the throne that symbolized supreme power.

He is the former King of Hueco Mundo who, after Aizen's death, regained his throne in Hueco Mundo with his unparalleled abilities.

Bayragang Ruisenbang.

At this moment, the two purple flames of his soul in his eye sockets were quietly "watching" the images that Ulquiorra was sending back.

When he saw Lynn, that tiny, seemingly fragile child, his soul's fire remained undisturbed.

They're nothing but ants.

When he saw Kaido, Whitebeard, and those enormous monsters exuding a terrifying aura, his soul fire remained unmoved.

Even the most powerful creature cannot resist the power of "aging".

but.

When he saw Lynn, he simply waved his hand, causing Yamamoto Genryusai's Bankai, the power of the rules representing "flame" and "end," to be extinguished out of thin air.

When he saw Lynn, with just a snap of his fingers, distort the "reality" of the entire Seireitei from a "conceptual" perspective.

For the first time, the pair of bony hands on the armrest of the Barragán throne unconsciously clenched their fists.

His pair of purple soul flames flickered violently.

He sensed from that child a power on par with, or even higher than, his own "aging" power!

That was an absolute threat, enough to challenge his throne!

"interesting……"

A hoarse sound, like the grinding of dry bones, echoed in the empty royal palace.

"What interesting ants..."

"How dare they attempt to encroach upon the realm of the gods..."

Barragán slowly rose from his throne.

A terrifying aura of decay and death, seemingly capable of halting time, emanated from his skeleton.

"Pass on my orders."

His voice was cold and authoritative.

"Send all Espada to battle!"

"Tell those arrogant invaders..."

"In this land, there is only one God, and that is me, Barragán Ruisenbón!"

"Let them turn to dust in the face of 'aging,' and experience true despair!"
