The Secret of the Void Century

There were four rulers in the prosperous kingdom, serving as ministers to the king. Each of them was entrusted with a legendary weapon, which could be either physical or a supernatural power.

 The rulers were:

 Ruler of the Sea

Controls all sea creatures through Poseidon

 Ruler of the Earth

Controls a massive ship powered by mysterious energy, capable of destroying entire islands — Pluton

 Ruler of the Forest

Possesses the weapon Uranus, powered by solar energy

 This is Imu

 Ruler of the Sun

Close to the king and the crown prince — Joy Boy (Nika)

Controls the source of energy itself, through a special power or weapon, and no one can use this energy without his permission

 In secret, the Ruler of the Forest (Imu) sent his “demons” to nations oppressed by the prosperous kingdom, starting a war.

 

 

While the kingdom was preparing…

Someone killed the king and stole the ultimate energy source

 After the king’s death, the world split into two sides:

 One supporting Nika (Joy Boy)

 The other seeing him as foolish and unfit to rule, even as the king’s son

 Imu sought one thing in secret:

 Eternal immortality

When Nika confronted him and declared rebellion, the Ruler of the Earth was forced to submit.

 The Ruler of the Sea, enraged by this,

 cursed all “demons”

 forbidding them from the sea

As a result:

 Devil Fruit users become weak when touching water

 Imu continued conquering the world and enslaving all races, alongside his new allies.

As for Nika, he was taken by the Ruler of the Sea to the depths of the ocean, where he planned his return to defeat the immortal devil.

 Lacking a sufficient army,

he decided to form a pirate crew

 Becoming:

 The first pirate in history

He set sail, abandoning the title “Ruler of the Sun”

and adopting the name Joy Boy

 Imu managed to control the elephant Zunesha, forcing it to fight on his side — a grave sin.

When Joy Boy returned, he punished Zunesha…

 condemning it to wander the seas and obey the Kozuki clan

 Before that, Joy Boy secretly contacted the Ruler of the Earth and agreed to:

 Hand over Pluton

 Hide it beneath Wano

Then the Ruler of the Earth fled and became a pirate as well

 Joy Boy also made a deal with one of the kings allied with Imu,

to betray him at the right time, and tasked him with spreading the Poneglyphs after defeat

 The final battle began…

A brutal war where all legendary weapons were used

 The result:

 The world sank by 200 meters

 The end of the prosperous kingdom

 Imu emerged victorious…

And erased the entire battle and its history

 The World Government was established

 The Celestial Dragons rose

 But the victory was not complete…

 Joy Boy destroyed the energy source (the “Sun”)

and no one could ever restore it

 He hid the One Piece

and declared he would return after hundreds of years

 Passing his will to the future

 Imu became the ruler of the world…

but lived in fear of the “promised day” for centuries

 As for the Ruler of the Earth,

who initially sided with Imu but later betrayed him,

he hid his clan and became a pirate

 Becoming:

 The second pirate in history

He was a user of the Dark Fruit

 And the ancestor of:

 Davy D. Jones / Teach
