Confrontation Between the Four Emperors!

Impel Down, the Undersea Prison.

Level 6, inside a private single-cell Little Black Room.

Roya was still sitting there with his eyes closed, cultivating, while Magellan remained on guard over him, completely unaware of what was happening outside.

Even if Magellan had known about the situation outside, he might not have been able to spare attention for it.

Because Magellan knew very well that this place could not possibly hold Roya. If Roya took advantage of a moment when Magellan was not personally guarding him, he would most likely use the chaos to escape.

If Roya really did escape, Magellan believed that without him here, no one would be able to stop Roya.

Even with Magellan present, he might not necessarily be able to stop Roya.

Watching Roya rest with his eyes closed, Magellan remained constantly on edge. Perhaps in Magellan's eyes, Roya was a sleeping beast. Once that beast awoke, the consequences would be unimaginable.

At this moment.

Big Mom had already broken through to Level 6.

"Kaido!"

"You troublemaking bastard!"

"Get out here!"

The moment she arrived on Level 6, Big Mom let out an enraged roar.

Her roar echoed through the entirety of Level 6, and the walls trembled slightly along with it.

All the great pirates being held there turned their gazes toward Big Mom.

At once!

Everyone's eyes widened in astonishment.

"One of the Four Emperors, Big Mom!"

"Why is she here?"

Bullet, Red Count, Sanjuan Wolf, Donquixote Doflamingo, Crocodile, Fire Fist Ace, and many other infamous great pirates were stunned by Big Mom's arrival.

Even Shiryu of the Rain, who had never spoken before, underwent a drastic change in expression.

These were all notorious great pirates imprisoned on Level 6 of Impel Down!

As for the weaker great pirates, they were utterly dumbfounded.
