The Tenseigan revealed cracks in the glass of the convenience store refrigerator as Utsusemi's fingernail scraped across the electronic price tag reading 2025.08.31.19:15.

Utsusemi stared at the yogurt in the refrigerator and used lipstick to write the number of days since her transmigration on the reflective glass.

The rules here were strange. Every trace would slowly fade under the effects of stopped time.

In less than half an hour, the writing on the glass would vanish completely.

Only the memories in her mind kept reminding her that she had drifted through this dimension that did not belong to her for thirty-six days.

Beyond the glass curtain wall of the Spacetime Tower, the Tenseigan caught a cruel scene.

Five adult shinobi were closing in around a child of only seven or eight, attacking him from all sides.

The child's black-and-white hair stood out starkly amid the smoke of battle. He wore ill-fitting armor.

Clutching an unsuitable weapon, he struggled to hold out against the five blue-clad shinobi trying to kill him.

In less than a quarter of an hour, the brutal fight was over.

The shinobi left a scene of devastation behind and vanished into afterimages at the edge of the battlefield.

Through the Tenseigan, Utsusemi could clearly see that the dying child's eyelashes were still trembling as he lay in a pool of blood. He still had one breath left.

Utsusemi hesitated for half a second beside the glass curtain wall. There was no one left on the battlefield.

A moment later, and the child would be beyond saving.

She charged into the smoke and leaped into the distorted battlefield.

When she returned with the black-and-white-haired child in her arms, she noticed an absurd sight: the droplets of blood at his wounds had stopped moving.

The child was pinned in a crack in time, an eternal specimen under the rules of the Spacetime Tower.

Utsusemi looked down at the small, thin body in her arms. A child this young should have been nestled in his family's arms, seeking their affection.

Why did he have to clutch a weapon that did not belong in his hands and fight five adult shinobi to the death?

Where was his family?

What kind of cold-blooded devil was his guardian, to push such a young child onto the battlefield?

She thought no further, carrying the child into the high-speed elevator and pressing the button for the top floor.

The elevator car shot upward, the numbers jumping from 1 to 93.

The entire Spacetime Tower was like a miracle grown out of another dimension.

The ninety-third and top floor was like a building block casually tossed by a giant god, lodged at an angle in a crack between dimensions.

Beyond the glass curtain wall, the afterimages of the battlefield were like a forcibly projected 4D movie, blades flashing just outside the windows.

Utsusemi did her best to look away from the bloody scenes a kilometer away.

She carried the child to the far end of the observation deck and stopped before the bronze mirror embedded in the wall.

Intricate Ōtsutsuki crests were engraved around the bronze mirror's frame.

It was the most amazing thing she had discovered since arriving here.

She remembered the first time she had seen the bronze mirror, when ripples like those on water had spread across its surface.

Countless fragments of memory had streaked through her mind like meteors: a higher-dimensional life-form of pure energy, and a quantum protective layer called "Hagoromo."

Hagoromo enveloped her soul, allowing her to travel between the other dimension and the Warring States, but this power was imperfect.

Once she lost control of her emotions, the rampaging Tenseigan would burn her brain.

She had to remain relatively calm.

There was also that gift expressed in the language of Chakra:

"Thy soul shall complete the string missing from this world."

But after that, the bronze mirror had shown no further activity.

Transmigration had given Utsusemi unimaginable power. Reason told her she should set up a laboratory to analyze the Tenseigan.

But instinct drove her to use ????? on the moon.

The Ōtsutsuki bronze mirror finally reacted. A black Tomoe branded the first rune onto the child's shoulder blade.

A whirlpool mark flowed along his spine to form the second, while two fork-like crests climbed up from his ankles.

The Spacetime Tower trembled, and the surroundings of the Warring States battlefield outside sped rapidly forward.

Was time speeding up?

Ten years passed in a brief ten seconds.

Utsusemi understood that the child had signed a contract with her and become her vassal.

The courage of the black Tomoe, the rebirth of the whirlpool crest, and the wisdom of the two-pronged crest all became a glowing bloodline.

Vines covered in flowers of every color poured from his fingers and climbed up Utsusemi's wrist.

Utsusemi felt no fear. Instinctively, she pressed her palms together. "Yin-Yang Release."

The restorative power of Yin-Yang Release traveled in reverse, creeping along the vines toward the child's wounds.

The wounds gradually began to heal. The vines flowed back up from Utsusemi's fingertips, and the flowers turned into liquid memories.

The memories of Itama Senju's brief seven years came flooding in like running water.

Six Paths Mode, which could only be maintained for five minutes, was now extended through the harmonizing effect of Flower Release.

Courage, rebirth, and wisdom were all transformed into longer-lasting Chakra reserves.

Six Paths Mode could be extended to half an hour, with a cooldown of only six hours.

It was just like the Ōtsutsuki crests completing a full cycle of spacetime within her body.

When Utsusemi formed Hand Seals again, Flower Release vines grew from her palm.

Every petal could steal another person's Chakra, moisture, and even life force.

Anyone ensnared would initially feel only a slight tingling. Their Chakra would flow into the flowers until they were drained dry and strangled.

"Rather than flowers, this is more like a strangler fig," Utsusemi said with a sigh, looking outside the Spacetime Tower.

Now she had formally signed a sharing contract with the child in her arms, Itama Senju.

Golden contract script climbed from their clasped palms and flowed through their bloodlines, spreading throughout their bodies.

The next second, those unfamiliar, tongue-twisting languages naturally entered her mind.

Whether it was ancient seal script on a blade or the dialect spoken by clan members, she could understand and speak it.

The contract not only bridged the gap in speech and writing, but also brought her two weighty gifts through the bloodline of the Senju of the Forest.

One was the Flower Release Kekkei Genkai, a lesser derivative of Wood Release.

The other was the Sage Body, inscribed in the deepest reaches of the Senju bloodline and passed down from generation to generation.

Before, she had possessed the power of the Tenseigan, but her physique had been no different from an ordinary person's.

Now, vast vitality surged through her veins and spread throughout her body. She was no longer an observer too weak to truss a chicken.

She was no longer a transmigrator who could only hide in the Spacetime Tower and observe the Warring States through glass.

She had finally gathered enough strength and courage to step into that unknown world of flashing blades and bloodshed.
