In modern Japan, a 15-year-old boy dies unexpectedly and is reincarnated into another world as the third prince of the Kingdom of Noctis. Although he retains his memories, no one knows that he comes from another life.

At the age of five, his mana awakens. Instead of fire, water, wind, or light, he possesses a mysterious ability called World Gate—the power to open portals to countless imaginary realms. The kingdom's scholars declare it a "worthless" ability because it cannot be used directly in battle or to increase military strength. Everyone believes it is a useless gift.

His father, King Aldren, is furious. Believing the prince has brought shame upon the royal family, he decides to execute him in secret.

Just before the execution, the crown prince—his older brother—steps forward.

"There is one place," he says. "The Forsaken Valley. Criminals, exiles, and forgotten people live there. Send him there instead. If he survives, then it is his fate. If he dies... we lose nothing."

The king agrees.

Banished with nothing but worn clothes, the young prince is thrown into the valley that everyone calls the Land of the Forgotten.

But everything changes.

The World Gate isn't weak.

Behind its portals are endless fantasy worlds filled with forgotten magic, ancient dragons, mythical forests, floating cities, legendary weapons, lost civilizations, and powerful teachers. Every world has different rules, allowing him to learn abilities that no one in his own world has ever seen.

Instead of becoming stronger by fighting monsters alone, he gathers knowledge, medicine, technology, farming methods, magic, and allies from countless worlds.

The starving valley slowly transforms into a thriving city.

People once abandoned by the kingdom begin calling him their true prince.

Meanwhile, another soul has also been reincarnated.

A 14-year-old girl named Yoshi awakens in the same world with memories of her previous life. She possesses a rare blessing known as Nature's Covenant. She can communicate with and command every non-human species—wolves, birds, dragons, spirits, insects, sea creatures, magical beasts, and even ancient monsters. Humans alone are beyond her control.

Unlike others who force monsters into submission, every creature willingly follows her because they recognize her gentle heart.

One day, while protecting injured creatures in the forest, she meets the mysterious prince from the Forsaken Valley.

At first they argue.

He trusts no one.

She believes everyone deserves kindness.

But as they travel together, they discover their powers complement each other perfectly.

His portals let them explore impossible worlds.

Her gift allows every magical creature there to become their ally.

Together they uncover an ancient prophecy:

"When the Gate Walker and the Voice of Beasts walk together, the worlds long separated shall become one."

As kingdoms begin hunting them, they realize the greatest threat is not monsters—it is the rulers who fear the truth behind the World Gate.

The abandoned prince who was called worthless may become the greatest king in history... and the girl who can command every living species may decide the fate of every world connected to his gates.

The cold wind stung Ren's face as the soldiers shoved him off the cliff.

"From this moment," one of them shouted, "you are no longer a prince!"

Ren rolled down the rocky slope until he crashed into the ground below.

For a few moments, everything was silent.

He slowly stood up, brushing the dust from his clothes. Looking around, he found himself in a vast valley surrounded by towering mountains. Old wooden houses stood scattered across the land, and the people who lived there looked tired, hungry, and hopeless.

"So... this is the place they throw away the people they don't want," Ren whispered.

An old man approached him carefully.

"Another exile?" he asked.

Ren nodded.

Instead of introducing himself as a prince, he simply smiled.

"My name is Ren."

The villagers welcomed him with what little food they had. Their kindness surprised him.

That night, Ren couldn't sleep.

He remembered the power everyone had laughed at.The moon hung high above the Forsaken Valley.

Everyone was asleep.

Ren sat alone on a cliff, staring at the stars.

"They called my power... worthless."

He clenched his fists.

"If this gate can connect worlds... then somewhere... there must be a place where I can become stronger."

The moment those words left his lips, a brilliant blue light spread across the valley.

A giant golden gate appeared before him.

Unlike the first portal, this one was covered in ancient symbols.

As Ren reached out, countless glowing letters appeared before his eyes.

Without hesitation...

Ren pressed YES.

The ancient gate slowly opened.

Instead of darkness...

A beautiful world lay beyond it.

Floating islands drifted across the sky.

Crystal rivers glowed beneath waterfalls that flowed upward.

Massive trees touched the clouds.

"This..."

"...is another world."

Ren stepped through the gate.

The portal closed behind him.

At that exact moment...

A tiny white fox with glowing blue eyes peeked from behind a crystal tree.

It was injured.

Ren slowly knelt beside it.

"Easy... I'm not here to hurt you."

The little fox looked into his eyes.

For the first time in thousands of years...

It trusted a human.

As Ren gently healed its wound with herbs, the fox rubbed against his hand.

A notification appeared.

The little fox suddenly glowed.

"I've waited... so long..."

Ren froze.

"You... can talk?"

The fox smiled.

"My name is Lumi."

"I am one of the last Guardians of the World Gate."

Before Ren could ask another question...

The entire sky trembled.

An ancient voice echoed across the sanctuary.

"Welcome..."

"...Successor."

Far above the floating islands...

Something enormous slowly opened its eyes.

The enormous eyes watched Ren from the sky.

He instinctively took a step back.

"...Who's there?"

The clouds slowly parted.

An ancient dragon, larger than a mountain, descended from the heavens. Its silver scales reflected the stars, and its golden eyes carried the wisdom of countless ages.

Ren froze.

The dragon lowered its head.

"You... are the new Gate Walker."

Lumi bowed respectfully.

"Master Aurelius."

The dragon looked at Ren for several seconds before speaking again.

"You are weak."

Ren frowned.

"I know."

"But..."

"You possess something no one else has."

The dragon raised one claw, and hundreds of glowing gates appeared around them.

"The World Gate."

"Most believe it is only a portal."

"They are wrong."

"It is the key that connects every realm, every civilization, and every forgotten form of knowledge."

Ren looked at the floating gates in amazement.

"So... I can learn from every world?"

Aurelius smiled.

"If you are worthy."

Suddenly, another blue screen appeared before Ren.

Ren accepted without hesitation.

The world around him changed.

He found himself standing in a circular stone arena surrounded by ancient statues.

A calm voice echoed through the arena.

"Power begins with control."

"Control begins with patience."

Hundreds of glowing mana orbs floated into the air.

Ren reached for them, but they scattered.

Again.

And again.

Hours passed.

Then days.

He failed more times than he could count.

Frustration built inside him.

"I can't even control one..."

Lumi jumped onto his shoulder.

"You've stopped trying to understand them."

Ren blinked.

"...Understand?"

"Mana isn't your servant."

"It's your partner."

Ren closed his eyes.

He slowed his breathing.

Instead of forcing the mana toward him...

He let it come to him.

One tiny orb floated into his hand.

Then another.

Then ten.

The entire arena glowed.

Aurelius nodded proudly.

"Many seek power."

"Very few seek understanding."

Ren smiled for the first time since his exile.

"I'll become stronger."

"Not so they fear me..."

He looked toward the distant sky where his kingdom lay beyond the mountains.

"...But so no one can ever decide my fate again."

Hidden in the shadows, another figure silently watched the training.

A woman wearing a silver mask whispered,

"So... the next Gate Walker has finally awakened."

She disappeared before Ren noticed.

Far away, in another part of the continent...

A 14-year-old girl with long black hair streaked with blue gently held out her hand.

A wounded wolf approached her without fear.

The wolf lowered its head.

Moments later, dozens of birds landed around her.

Then deer.

Then foxes.

Then magical creatures that ordinary people had never even seen.

The girl smiled softly.

"I don't know why..."

"...but I feel like someone important has arrived in this world."

For the first time...

The paths of Ren and Yoshi had begun moving toward each other.
