The fight with Rocks D. Xebec had gone badly.
Yuuichiro's strikes had landed, but Rocks' sheer weight of experience and the crushing force of his Haki had overwhelmed him. And then came the sound he had been dreading—crack.
His Bloodline Pool Bracelet, the only anchor back to his own universe, split during a clash. In that instant, he realized he couldn't return home — not yet.
And so, when Rocks barked an order, Yuuichiro accepted a lesser role. He joined the ship as a cadet under Kaido's unit, knowing it was the only way to learn this world's rhythm, power, and politics without being discarded.
Kaido had seen something in him — the hybrid bloodline, the stubborn refusal to break entirely even after losing. He didn't ask questions, just pointed Yuuichiro toward the crew's duties.
Days turned into weeks. Out at sea, Yuuichiro hunted beasts the size of fortresses—sea kings with jaws wide enough to swallow boats. Their meat was rich, their blood heavy with energy, and every meal pushed his body to new thresholds.
The blend of Saiyan bloodline and Kaido's monstrous vitality was changing him from the inside; each breath drew in more strength, each sunrise left his body harder, faster, tougher.
Then came that night.
A full moon hung clean and bright over the open ocean. Yuuichiro was on the main deck, his meal half-eaten, when instinct hit him like a lightning strike. His body froze, breath coming faster — and then the growth began.
His muscles swelled, bones lengthened, fur erupted across his frame. Tail bristling, claws gouging the deck, he rose until he towered above the main mast.
The Great Ape form of the Saiyan bloodline had taken him — but he was too enthralled to fear it.
The crew went dead silent. Pirates on deck stopped mid-task, jaws slack, staring at the massive beast that was once a man. Even Kaido squinted up at him, intrigued more than afraid.
Yuuichiro flexed his new form and roared, a sound that rolled out across the waves like thunder. Maybe, he thought, this was what his bloodline was always meant to become.
Meanwhile — Original Universe, Zoldyck Estate
In the lounge, Haruko sat across from Yujiro and Baki, explaining the fundamentals of the Saiyan bloodline.
"We can transform into a Great Ape under the full moon," Haruko said plainly. "It multiplies power enormously. With training, it's controllable — but the tail is our weakness. Lose it, and the form is gone until it regrows."
Yujiro leaned back, processing the implication. Baki looked skeptical, but curious.
Haruko excused himself briefly and returned with a large machine, smooth and metallic, screen glowing faintly with unknown symbols.
"This," Haruko said, resting his hand on it, "is from my bloodline world. It contains not just fighting techniques, but advanced scientific knowledge from there."
Yujiro's brow arched. "Science knowledge?"
Haruko nodded. "I'm thinking of using its schematics to build a Gravity Chamber here."
Grandfather Zenny — who had been quietly listening nearby — finally rose from his seat, his eyes sharpening in interest. "And what exactly is this chamber?"
Haruko's hands moved over the machine's interface. "In short — it can increase gravity to extreme levels in a contained space. Your body trains under much heavier pressure than normal. In Saiyan culture, it's one of the fastest ways to develop true strength and durability."
Baki's eyes widened. "So you're saying… this thing could make us stronger than any normal training?"
"Far stronger," Haruko confirmed. "Physical power is the base for what comes after — the Super Saiyan transformation. If you can't survive multiplied gravity, you'll never make it there."
Even Yujiro's interest sparked — though his voice stayed even. "So in that world… what are we compared to them right now?"
Haruko looked him straight in the eye. "In that world, one powerful fighter could destroy an entire planet. By their standard, without transformation, we're nobodies."
For a moment, even the confident smirk faded from Yujiro's face. Baki glanced at his father, then back to Haruko, the weight of those words settling in.
Zenny's voice broke the silence and created big smile looking at big machine created by shernon "Then we'll build it. And let me put call my friends and clan member all over the world to summoning meeting "
