All-Killing Ash Bones!
Shinji unleashed two sharp, gray bones from his hands in an instant. The moment they struck Boros, his body began to wither and collapse, disintegrating into fine ash within seconds.
"Ohhh!!"
Yet Boros' body reformed almost immediately, his regeneration erasing any sign of injury. Even so, the technique had bought Shinji a few precious seconds. Without hesitation, Shinji teleported high into the sky, closing the distance to the moon in an instant.
His Rinne Sharingan, which had been open in its normal state, now widened until it was almost perfectly round. At the same time, the moon, nearly full and pale against the once-clear sky, underwent a sudden transformation. Its silver glow turned crimson, and an intricate Rinne Sharingan with nine tomoe appeared on its surface.
"The moon...? What's happening?!"
"It looks just like the [Kamui] eye! Did he do this?"
"This power... it's beyond anything imaginable..."
The eerie blood moon hung above the Earth, leaving those below frozen in awe and fear.
"Shine upon the world, Infinite Tsukuyomi!"
Shinji formed a one-handed seal, pressing his index and middle fingers vertically before his Rinne Sharingan.
"Now... become one."
As the final hand sign was completed, a faint, colossal image of Otsutsuki Kaguya appeared in the heavens. She looked down upon the planet with a sinister smile, the blood moon positioned like a jewel at her brow.
Shinji's expression remained steady as he met her illusory gaze. Unless Kaguya could truly manifest in this world, she was harmless to him. And even if she did appear, he still held his ultimate trump card: the Flying Thunder God, Saitama Summoning Technique.
The next moment, the Infinite Tsukuyomi activated. The blood moon's surface erupted in a blinding radiance, casting its light across every corner of the Earth. No matter how deep in the mountains, far underground, or sealed within buildings, no human could evade its glow.
Only Tatsumaki reacted in time, instinctively raising an energy barrier around herself and the other S-Class heroes. The shimmering wall shielded them from the moon's illusion.
If Shinji had wished, one of his wooden clones could have shattered that barrier instantly, trapping them in the dream. But there was no reason to bother.
Saitama, originally within Tatsumaki's protection, found himself outside its safety when he reached for the sunflower seeds he and Shinji had been sharing. They were sitting on the ground just beyond the barrier, and his casual reach accidentally poked a hole through it.
"What's this? Bubble gum?"
When Boros finally moved to attack, the Infinite Tsukuyomi and the Divine: Birth of the Tree World were already in effect. Instead of striking right away, he hesitated, his gaze fixed on Shinji high above and on the massive blood-red sphere hanging in the sky.
By now, people across the world were already offering their strength to Shinji. In the shadow of humanity's possible extinction, very few could stand idle. Most lifted their arms toward the sky, letting the faint life force within them flow away.
Even Psykos, deep beneath Z-City, had fallen under the Infinite Tsukuyomi's sway. She knew Boros could achieve her dream of wiping out humanity, yet she chose to support Shinji instead. In her mind, if humanity's end was ever to come, it should be brought about by her and Shinji, not by an alien conqueror like Boros. Without hesitation, she gave him her share of energy, trusting him absolutely.
Though the power from each person was meager, most being ordinary humans, when multiplied by billions, it became something far greater. The Divine Tree didn't need to trap anyone with vines; it simply absorbed their willing offerings and transmitted them instantly to Shinji.
"I see… so this is your ultimate move!"
Feeling Shinji's power surge without limit, Boros understood that his opponent intended to end their battle decisively.
"In that case, I'll show you my own final technique!"
An immense and violently destructive energy began to gather within Boros' body. "I'll unleash everything I have and erase you, along with the entire surface of this planet!"
As their powers climbed higher and higher, the overflow lashed out like endless bolts of lightning, striking the heavens and the ground alike. The skies shifted in color, and the earth trembled violently.
"Ohhh, ?!"
"What's happening?"
"They're going to decide it now! Everyone, take cover!"
The heroes below turned pale with dread.
Collapsing Star Roaring Cannon!
The moment Boros completed his gathering of power and released his devastating attack, Shinji had just absorbed the final fraction of humanity's energy.
Amenominaka!
In a single instant, Shinji pulled Boros into a vast spherical dimension. There, he transformed into the Ten-Tails and conjured an enormous Truth-Seeking Ball that continued to expand without end.
Final Truth-Seeking Ball!!
