Screen 1 — Prisoners of Udon
Luffy and Ben, now in Four Arms form, are thrown into Udon Prison, a brutal labor camp run by Kaido's forces. Heavy sea prism restraints limit their strength, forcing them to work under constant surveillance.
As they haul massive stone blocks, Luffy locks eyes with another chained prisoner.
It's Eustass Kid.
Kid smirks despite the pain.
"So the rumors were true. Straw Hat… and his alien."
Luffy grins back, battered but unbroken.
"Guess we all ended up in the same place."
Ben clenches his four fists, calm but focused.
"This prison isn't the end. It's a pressure cooker."
The guards laugh, unaware that they've just gathered three monsters in one cage.
Screen 2 — Signs of War
Shinobu and Nami secretly investigate the outskirts of Udon and uncover massive weapon forges operating day and night. Blades, rifles, and cannons are being produced in huge numbers — clear proof that Kaido is preparing for a full-scale war.
Nami whispers that this isn't just for Wano. These weapons are meant for something bigger.
Shinobu adds another troubling detail. Some of the machinery does not match Wano or Beast Pirate craftsmanship. The designs look advanced, experimental — science-driven.
Nami narrows her eyes.
"Someone else is involved."
A single name surfaces in their thoughts.
Albedo.
If his science is already here, then Kaido's army is becoming far more dangerous than expected.
Screen 3 — Prison Strength
Luffy, Kid, and Ben — still in Four Arms form — continue their brutal labor in Udon Prison.
Even with seastone handcuffs draining their strength, they refuse to break.
Luffy and Kid carry massive stone blocks meant for dozens of prisoners, turning punishment into competition.
They glare at each other, pushing harder with every step.
Ben plants his feet, four arms tightening around the chains and stone.
Despite the seastone, his raw physical power still shows.
Ben (low voice): "This prison thinks strength is enough to break people. They don't understand will."
The guards watch in shock.
These prisoners aren't being crushed — they're enduring.
Udon doesn't realize it yet, but it's holding three fighters who will soon turn this prison upside down.
Screen 4 — Food, Fury, and Resolve
The prisoners are given food tokens as rewards for labor, but Luffy, Kid, and Ben consume huge amounts just to stay standing.
The guards grow irritated as their supplies vanish faster than expected.
Daifugo, the vice-warden with the Hippo SMILE, storms in and attacks an old prisoner for slowing down.
Before the guards can react, Luffy steps in, taking the blow meant for the old man.
The prison goes silent.
Ben's eyes narrow.
Ben (quiet, controlled): "So this is how Kaido's world works. Strong eat. Weak disappear."
He clenches his fists, chains rattling.
Ben (to Luffy): "You didn't hesitate. Good. That's why people follow you."
The old man trembles in gratitude.
The guards feel it — something is changing.
Ben doesn't attack. Not yet.
But his posture shifts from prisoner to problem.
Ben (under his breath): "Keep pushing us. Udon won't survive it."
Screen 5 — An Unwanted Ally
Deep inside Udon Prison, a familiar voice echoes from the shadows.
Caribou slithers forward, grinning nervously, chains clinking at his wrists.
Caribou: "Straw Hat! Alien guy! What a reunion, huh? Listen, when you two break out of here — and you will — take me with you!"
Luffy squints at him. "Didn't we throw you away already?"
Ben crosses his arms, unimpressed.
Ben: "You're still alive. That's either luck or a bad sign."
Caribou lowers his voice, leaning closer.
Caribou: "I know things. Big things. About Kaido. About weapons. About Wano."
Ben's expression hardens slightly. He studies Caribou the way a scientist studies a leaking container.
Ben: "You also stab people in the back the moment it's convenient."
Caribou chuckles nervously. "Hey, survival's survival."
Luffy looks away, uninterested. "I don't trust you."
Ben nods. "Same. But information has weight."
He steps closer to Caribou.
Ben: "If you lie, I drop you back in the deepest cell. If you run, I catch you. If you hurt anyone — you don't get a second warning."
Caribou gulps.
Caribou: "…Deal."
From the corner of the prison, Kid watches and smirks.
Kid: "Heh. You two really attract garbage."
Ben doesn't respond. His eyes stay on Caribou.
Ben (quiet): "In a place like Udon, even garbage can explode."
