The Other Members of the Ōtsutsuki Clan

"Who is he?" Naruto finally spoke, his voice low and carrying a trace of unease.

Shinshiki stood in the middle of the room, dressed in a dark robe patterned with subtle designs. A faint silver glow shone in his eyes. He raised his head slightly and spoke in a calm voice, cold as ice: "The leader of the Ōtsutsuki Clan... the strongest being."

"What?!" Naruto spun around, his pupils contracting as he stared at Shinshiki in disbelief. "Stronger than Kaguya?"

The air seemed to freeze in an instant. The wind outside the window stopped, and even the leaves fell silent.

Shinshiki nodded slowly, his voice echoing like an ancient bell: "Isshiki... is the source of all Ōtsutsuki bloodlines. Kaguya was once his most loyal servant, but she later betrayed him and stole the God Tree's fruit. That was how the legend of the Ancestor of Chakra began. But before Isshiki, her power was no more than a faint glimmer."

"He... could destroy a planet with ease." Shinshiki continued, his voice level, yet Naruto's heart pounded wildly. "He once devoured three living planets by himself, turning them into desolate wastelands. And now—he has set his sights on Earth."

"When?" Naruto clenched his fist, his nails digging into his palm.

"Possibly tomorrow."

"Or next year."

"But he will come."

Shinshiki's tone was so firm it was suffocating. "Because there is something on Earth that he wants."

"What?"

"The God Tree's fruit." A complicated look flashed through Shinshiki's eyes. "It is the true source of the Ōtsutsuki Clan's power. Not Chakra, but something beyond Chakra—'Source Power.' Whoever eats it can not only gain immortality, but also control space and time, and even reshape reality. And Earth... happens to have the 'spiritual soil' and 'stellar veins' most suited to growing a God Tree."
