yotsuki Seiji Is the Distant Nephew of the Raikage

A translucent panel hovered before Seiji's eyes, flickering faintly in the dim morning mist.

[Water Treader (White)] – Progress: 25%

He had unlocked this entry shortly after beginning his water-walking training.

"Four more days," he murmured, watching the bar creep upward."...No—maybe less."

With that, he dismissed the panel and returned to his quiet grind—drawing out chakra, forcing it through his weary muscles, balancing on the edge of exhaustion.

Thanks to his mixed heritage, Seiji had more chakra than most.

The Uchiha were already known for their deep reserves of chakra—second only to the Senju and Uzumaki, clans hailed in the official record as "possessors of immense life force and chakra."

But Seiji had something else too.

The blood of the Yotsuki clan—the Night Moon clan—coursed through his veins.

Masters of Lightning Release. Brutal physical combatants. Shinobi molded by thunder and endurance.

This gave Seiji an edge that even the elite Uchiha lacked: sustained energy.

He could train longer, push harder.

In the ninja world, chakra is a fusion of spiritual energy and physical strength. To expand your chakra reserves, you must train both body and will.

But this also reveals a painful truth.

Most civilian ninjas reach a limit—the "cap" of their potential—early.No matter how hard they try, they rarely break past it.

Might Guy was the exception.

He opened the Eight Gates, burned up every last drop of his chakra in a brilliant blaze of power… just to touch the level of those born with divine blood.

Otsutsuki blood.

Seiji?

He had that lineage too.

Tracing back far enough, he too was a child of Kaguya.

Hidden Cloud Village – The Land of Thunder

The roar of the waterfall echoed across the canyon like rolling thunder.

From beneath the crashing torrent, a man emerged—his upper body bare, muscles like forged iron, the kanji for "thunder" tattooed boldly on his shoulder.

The Third Raikage.

"Any news, Tutai?"

A man in a black hat and a patch over one eye approached with a scroll in hand.

Dodai—trusted advisor to the Raikage.

"Yes, Lord Raikage. Yotsuki Seiji has made contact with our embedded agent in Konoha. Samudo's report is thorough."

The Raikage's massive palm clapped Dodai's shoulder—a sound like a thunderclap.

"Good. This can't go wrong."

"Understood."

"His lineage?"

"Confirmed," Dodai said, handing over the scroll. "His blood ties go back to the Second Raikage."

The Raikage's expression darkened slightly as he scanned the document.

"He's that Seiji? From Shuiyun Gorge?"

A small outpost. His family were merchants—weak shinobi who left the village to run clan businesses abroad.

Still, he was kin.

A distant nephew of the Second Raikage himself, the only Raikage to have hailed from the Yotsuki clan.

"He's an Uchiha now," Dodai added, "and not a threat to the line of succession. Your son, Ai, will inherit your position without challenge."

The Raikage didn't respond. The waterfall's mist blurred his sharp features.

After a long pause—

"His bloodline is too valuable. Bring him back. No matter what."

"Yes, Lord Raikage."

Back in Konoha – Several Days Later

Autumn rain fell in a soft drizzle, streaking the sky in gray.

Seiji held an umbrella and stepped into the courtyard.

Mikoto Uchiha stood at the entrance, looking as calm and refined as ever.

"Seiji," she said softly, "Fugaku asked me to invite you. There's a small gathering—just us clan members."

She wore simple casual clothes—a white dress, her long black hair cascading like silk. The rain only emphasized the elegance in her every movement.

"Sure," Seiji nodded. "Lead the way."

They walked together through the streets of the Uchiha district, the umbrellas tapping softly against the rain.

Flame fan crests adorned the walls, flags, and wooden posts along the road—silent witnesses to their lineage.

Fugaku's Home – Backyard

Boom!

A great fireball roared through the air, evaporating raindrops before they could land.

Fire Style: Great Fireball Technique.

The Uchiha signature.

Fugaku stood shirtless in the rain, breathing heavily from exertion.

When he saw them, he turned with a smile.

"Practicing outside in this weather? You'll catch a cold," Mikoto scolded.

"Heh, I'm Evil-Eye Fugaku. You think rain can stop me?"

He dispelled the flame, and the heat lingered as a warm mist.

"Come in," he said, turning toward the house. "I was just finishing up."

Seiji followed them inside. He removed his shoes at the wooden corridor and stepped onto the polished floorboards.

Mikoto had already entered, her steps quiet and graceful.

"I had Mikoto prepare these," Fugaku said, gesturing to the table full of food. "Give it a try."

The smell of warm rice, grilled fish, and seasonal vegetables filled the room.

Seiji blinked.

"You're really good at this, Mikoto."

"Fugaku kept insisting," she said, slightly flustered. "It's not much."

But this was Mikoto's first time visiting Fugaku's home.

Among the Uchiha, traditions weren't as rigid as the Hyuga, but there were still boundaries.

Unless their relationship was official, she wouldn't be here casually.

If not for Seiji's presence… perhaps she wouldn't have come at all.
