Momoshiki, like any Ōtsutsuki, had pale skin and bluish-gray hair that cascaded down his back in long strands.
After absorbing Urashiki, his body underwent a drastic transformation—one that Kaguya was grateful she hadn't experienced after absorbing three Ōtsutsuki consecutively.
Black markings covered almost his entire body, including his face and chin, forming patterns similar to checkered designs. His Dōjutsu, the Rinnegan, was golden, while a third eye seemed to have sprouted from his forehead.
His horns also lengthened and curved backward, covered by the same dark markings.
"I must admit, this appearance suits you better than the previous one. At least now you don't look like a sanctimonious fool," Kaguya remarked with a mocking smile.
"Your words do not affect me, traitor. I will not fall for such a lowly trick," Momoshiki replied coldly.
"Why would I bother using such a cheap tactic against someone inferior to me? It makes no sense," Kaguya retorted, shaking her head in amusement.
Momoshiki frowned and gritted his teeth, forcing himself to remain calm.
Kaguya had decided to toy with him. Momoshiki possessed a severe superiority complex, considering everyone—even members of his own clan—as lesser beings. She was determined to prove him wrong.
Killer B, in an attempt to help, fully transformed into Gyūki and fired a Bijūdama at Momoshiki. However, he simply extended his hand and absorbed it, much to the dismay of those present.
"Idiot," Kaguya muttered, watching as Momoshiki returned the Bijūdama with even greater power.
If not for Hashirama, who shielded the crowd, many civilians and Shinobi of Konohagakure would have perished in the attack. Even so, much of the stadium was reduced to rubble.
Kaguya allowed the Kage to regain their mobility so they could tend to the wounded. They understood the situation immediately, and none stood between her and Momoshiki.
Killer B, realizing his helplessness in battle, withdrew. Naruto asked him to rescue as many civilians as possible.
Surprisingly, the only ones left in the destroyed stadium were Naruto, Minato, Gaara, Boruto, and Kaguya.
Hashirama stood aside, determined to protect the survivors, while Tsunade healed the injured.
He glanced at Boruto and shook his head. He had inherited his father's recklessness.
Gaara used his sand to clear the debris while Minato teleported to ensure the civilians' safety.
Naruto, ready to join the fight, tensed upon hearing Kaguya's voice.
"Get your brat out of here."
Naruto finally noticed her presence and, worried for Boruto, immediately nodded in agreement.
"When I defeat Momoshiki, I don't want him to grant Boruto the Karma and gain a chance to revive in the future."
Momoshiki, aware that Ninjutsu would be useless in this battle, created a Bō with his Chakra to engage in close combat against Kaguya.
Isshiki's Dōjutsu appeared on Kaguya's right palm, displaying a pattern similar to a wheel with eight bars radiating from the center of the pupil.
Several black stakes floated around her, while enormous cubes levitated above them.
"You absorbed Isshiki," Momoshiki stated, frowning.
Kaguya didn't respond. Instead, she reduced the stakes to a microscopic level and fired them at him.
Momoshiki barely saw them and struggled to dodge, but he couldn't avoid the cubes that rained down on him from above.
The battle raged on, destroying everything in its wake.
Aware of the destruction, Kaguya transported the fight to her desert dimension.
She raised her hand to the sky and used the Sukunahikona technique from the Kokugan Dōjutsu in her right palm.
Giant cubes began to fall upon Momoshiki.
He dodged one and smirked... but another appeared in the sky.
He dodged again... and yet another emerged from nowhere.
The pattern repeated for minutes until Kaguya grew bored of watching him evade.
When the cubes finally stopped appearing, Momoshiki barely had time to catch his breath before feeling a sharp pain—a black stake had pierced deep into his shoulder and leg.
Half-kneeling, he saw Kaguya appear before him, wielding a Chakra scythe created from Kinshiki's Ōdachinagi.
Just as his head was about to be severed, a turtle-shaped artifact appeared in his hands.
Kaguya's eyes widened.
"Karasuki!"
Karasuki was a tool of the Ōtsutsuki Clan used for time travel.
"How the hell does Momoshiki have it?"
In theory, Konohagakure would find Karasuki at the bottom of the sea and bring it to an archaeology lab for study.
Urashiki was supposed to be the one to steal it later...
But had Momoshiki been lucky enough to find it first? What kind of joke was this?
For the first time in the battle, Kaguya felt she had made a mistake.
She had been so confident in her victory that she stopped monitoring Momoshiki with her Senrigan.
And now...
"Activation confirmed. I am the ritual instrument Karasuki," a mechanical voice echoed.
"I will now recite warnings regarding my usage."
As this happened, Momoshiki managed to dodge her strike to his neck, smirking as he noticed her urgency to end the fight.
"I will review the usage procedure. An error in the sequence may affect the outcome."
"Lord Momoshiki Ōtsutsuki, to use me, you will need to charge me with Chakra. Once charged, select the displacement."
"You're too slow, turtle!" Momoshiki growled in frustration.
Karasuki floated into the air and began to shine intensely, blinding them both.
"Kaguya Baa-chan, we finally found you!" Naruto suddenly appeared alongside Sasuke, just as the blinding light pulled both Kaguya and Momoshiki in.
"We're too late..." Sasuke murmured, watching the empty space where they had been.
"B-but..." Naruto stared at the spot where Kaguya had vanished.
"I don't think she's dead," Sasuke said calmly. "Someone like her wouldn't die so easily."
