"So it's actually the More-More Fruit."
Hearing Yami's words, Robin couldn't help blurting it out.
"Robin, is that Devil Fruit really that strong?"
Seeing the always composed Robin finally show shock for the first time since learning Master is a multi-Fruit user, Carina and Nami both fixed their eyes on her, itching with curiosity.
In that moment, both girls felt the gap in vision and knowledge.
Compared with Master and this big sister, they were like country bumpkins.
Carina silently decided she had to build a good relationship with this big sister and learn from her, so her knowledge could grow fast and she wouldn't keep embarrassing herself.
"Mm…"
Robin nodded blankly, then a spark flashed in her eyes and she said with a hint of excitement, "If it's the Paramecia More-More Fruit, then it really is the most suitable for the Boss's abilities."
Seeing she had guessed it, Yami gave a thumbs-up. "Impressive. As expected of an Oharan scholar."
"Master, what are you two talking about?"
The riddle-speak only made Carina and Nami itch more.
Catching their pleading looks, Robin pressed her lips into a smile and explained slowly, "The Paramecia More-More Fruit is also called the Multiplication Fruit. Its eater twenty-five years ago was the two-hundred-million-Beli man known as the World Destroyer, Byrnndi World.
"The More-More Fruit lets anything the user touches have its speed, power, size, and weight magnified by set multiples, up to a maximum of one hundred times."
"Multiplication Fruit. One hundred times."
"So strong."
After listening, the narrow-horizoned Carina and Nami were left gaping.
Seeing they were amazed but had missed the key point, Robin went on, "Though powerful, the most terrifying part of the More-More Fruit is its strategic deterrence. As a single combat power it has limits.
"First, it cannot enlarge living beings other than the user. To magnify one's own speed and strength, you still need a strong body and stamina.
"Especially stamina. Without enough stamina, your self-buff and object buffs can't reach a hundredfold, or you can only use a few hundredfold boosts.
"If you lack weapons at hand, the fruit's greatest strategic deterrence can become meaningless."
"But…"
She paused, then the corners of her lips lifted. "Those shortcomings do not apply to the Boss.
"The Boss is an unprecedented multi-Fruit user. The More-More Fruit's multiplication can be applied to his other abilities.
"As long as his stamina holds, the Boss can magnify his powers up to one hundred times.
"For example, if the Boss had the Logia Flame-Flame Fruit, he could flick out a tiny fireball, then use the More-More Fruit to instantly make that fireball a hundred times larger, with no charge-up."
"So the Paramecia More-More Fruit really is the most suitable for the Boss. There is no second place."
"Hiss…"
As they pictured Robin's examples, Carina and Nami sucked in a breath, shaken to the core.
Yami gave Robin another thumbs-up.
As expected of the Straw Hats' future brain.
Just as Robin analyzed, the More-More Fruit fits Yami best, and it is the Fruit he wants most.
After gaining the Monster-born multi-ability physique, Yami longed to obtain the Logia Dark-Dark Fruit and the Paramecia More-More Fruit right away.
But the reason he chose the Dark-Dark Fruit first was to guarantee one hundred percent success when seizing Devil Fruits.
The Fruit he wanted most was actually the More-More Fruit.
Taking the Door-Door and Gaze-Gaze Fruits was also preparation for the More-More Fruit.
Because the More-More Fruit suits his physique even more than the Tremor-Tremor Fruit.
Once he has the More-More Fruit, Yami can seize other abilities, then magnify those techniques with the multiplier so that a casual strike becomes a world-shaking finisher.
More crucially, this power can make Yami himself grow larger.
What does that mean?
It means he can become a giant like Nika.
As for the possibility that higher multipliers consume more stamina, that is not a fatal flaw for a monster-born physique.
As long as he gets the More-More Fruit, Yami won't need to keep a low profile. He can stride openly across the seas.
That was why he was so eager to leave the starting island.
The next morning, their sailboat reached a small island.
This small island lay on the same route as the starting island Yami had reached.
But it was not the next destination the Log Pose would point to once it finished setting.
Earlier, every member nation of the World Government had a nearby Marine branch as a bodyguard.
Those Marine branches are built on islands near the member nations.
In the East Blue, branch locations are chosen more at random.
On the Grand Line, the Marines must consider magnetic fields.
After a Log Pose stores a full charge, it points to the next island.
Yet on the way there, a ship can encounter other islands.
Those islands have weak magnetic fields and are not required stops on the route.
Most Grand Line Marine branches are built on such weak-magnetism islands.
The island Yami reached was one of them.
After landing, Yami hauled the newly awakened and then re-knocked-out Poli Breed and went alone to the Marine base.
Half an hour later, Yami returned carrying a black case to Nami's cheers.
The bounty exchange went smoothly.
Grand Line Marines are unlike the corrupt ones in the Blues. Here, where pirates abound, they need bounty hunters.
After cashing in the bounty, the crew sailed back to the starting island.
Then, every half hour, Yami used Clairvoyance to check whether a prison ship had arrived.
With his stamina, he could go without sleep.
Even at night a prison ship couldn't slip past him.
Because of this, Yami made up for Carina and Nami by taking them back onto the starting island to enjoy themselves.
