In mythology, Izanami-no-mikoto was burned and tragically died while giving birth to the fire god Kagutsuchi-no-mikoto.
Her husband, Izanagi-no-mikoto, wept in grief, crawling over his deceased wife, and murmuring, "My dear wife! How could I have lost you because of a son?" His sorrowful tears transformed into a deity named Nakisawame-no-mikoto (The Crying Goddess).
After his lament, Izanagi-no-mikoto drew his Totsuka-no-Tsurugi and approached his son, the fire god Kagutsuchi-no-mikoto. "Even though you are my child, you cannot be forgiven!" he said. With that, he swung his sword and killed the fire god.
If "Yomi no Ikusa" was the collective choice of the Uchiha clan's spirits, then the ocular jutsu named "Nakisawame-no-mikoto" corresponds to the grief and hatred that Fugaku awakened after witnessing Itachi killing his mother! At the same time, it also corresponds to Fugaku's self-loathing over his indecisiveness and his prayer for a power that could bring him directly to his goal.
The effect of "Nakisawame-no-mikoto" is...
Based on one's own strength, as long as it's something one can do, it can reduce or even eliminate the process between the "cause" and the "effect." This ocular jutsu can achieve more bizarre and terrifying things.
But driven by the nearly instinctive anger and hatred of the white figure's consciousness, it brutally eliminated the process between "attack" and "hit"! It gave Hiruzen Sarutobi and the others no chance to help. From the perspective of others, its "attack" and Shisui's "being hit" happened almost simultaneously.
Crackle! Crackle!!
The punch smashed into Shisui Uchiha's body, which was protected by a verdant green skeleton. The already fragile skeleton instantly shattered and broke like rotten wood.
"Agh!!"
Shisui Uchiha let out a roar filled with pain and regret. Two glaring trails of bloody tears streamed down his crimson Mangekyō Sharingan! He no longer worried about the toll on his eyes or the consequences of going blind. He squeezed out the last bit of his ocular power, desperate to make up for the mistake he had made.
His Mangekyō Sharingan spun wildly. The once-dim flames in his Susanoo's eyes suddenly burst into a blinding light. The fractured ribs forcefully healed and regenerated!
Crackle crackle crackle!
A dense, heart-pounding sound of bone growth erupted like popping beans. The huge skull roared up to the sky, and its incomplete arm re-formed. The spine extended, outlining a more complete torso. Verdant green chakra, like veins and flesh, grew frantically, twisting and knotting at a visible pace! This flesh quickly covered the exposed bones and was then covered by a hard, solid layer of chakra armor!
Susanoo: Second Form!
At this moment, Shisui Uchiha's Susanoo, while still in the shape of a human torso, was no longer a grim skeleton. It was now a brawny giant with bulging muscles and a face. A uniquely shaped, gigantic weapon was held in its hand. It wasn't a traditional blade or a sword, but a spiral-shaped blade with a sharp, spear-like tip.
A force much more solid and ferocious than the first form surged forth!
"Die!!"
Shisui Uchiha roared hoarsely. His Susanoo's massive right arm bulged with muscle. It gripped the spiral blade tightly, channeling all its power into a forward thrust!
Tsk!!!
The spiral blade spun at high speed, tearing through the air with a deafening shriek! With a determined, all-or-nothing momentum, it mercilessly stabbed toward the pale figure in front of it.
The size difference between the two was immense in the eyes of Hiruzen Sarutobi and the others. But in the face of a strike that could pierce mountains, the pale figure still stood there motionless. Under its mask, the crimson Mangekyō Sharingan watched the approaching spiral blade.
Until the moment the spiral blade was about to hit its target.
Whump!!
An indescribably cold chakra, exuding a strong scent of blood and hatred, burst forth from the white figure's body!
Then, under the horrified gaze of everyone, including Shisui Uchiha.
Crackle! Snap!
The grinding sound of bones growing at a speed far exceeding Shisui's filled the air. Crimson chakra instantly condensed into thick, grotesque, giant bones! Dark red muscle fibers grew and twisted wildly like living creatures. White exoskeletal armor rapidly spread and covered four arms! There was no initial skeleton form! There was no first-stage growth process!
This monster's Susanoo skipped all the steps. Susanoo: Second Form was formed in an instant.
Ocular Jutsu: Nakisawame-no-mikoto!
This crimson giant was also in the shape of a human torso, but its form was more like a primal demon. Its four muscular, giant arms lifted up. Two of them crossed in front of its chest, palms facing outward!
Boom!!
A deafening roar accompanied by a visible shockwave suddenly exploded! Shisui's spiral blade, which had all his power condensed within it, struck the palms of the arms that were crossed in a defensive stance! The terrifying force instantly sent the surrounding trees and Hidden Leaf ninjas flying!
"Roar!!"
After a single moment of stalemate, the crimson giant roared like a living creature. It lifted its other two arms, its claws tearing through the air and leaving several crimson arcs.
Snap!
A crisp cracking sound echoed. The spiral blade was instantly sliced into several pieces by the claws' slash!
"Puh!"
The immense force passed through the defense, causing Shisui to spit out a large mouthful of blood again. His body shook violently as he knelt on the ground.
The Hidden Leaf ninjas watched the terrifying scene of what looked like a legendary monster battle from a distance: the ferocious and demonic crimson giant, and the verdant green giant struggling to hold on against its attacks like a candle in the wind! Feeling the horrifying fluctuations and bone-chilling aura from its every move, most people's faces were filled with unprecedented shock and fear.
Is this the true power of the Uchiha Clan? Is this the monster that Fugaku Uchiha became? Is this something that human power can contend with?!
Danzō's eyes continuously scanned the two Susanoos. Greed, fear, and a near-maniacal desire intertwined in his eyes!
"The Mangekyō Sharingan! This is the Mangekyō Sharingan!" Danzō's voice was like a trance, filled with indescribable shock and a hint of morbid excitement!
The next moment, the crimson demon giant raised its arms again. The crimson flames in the eyes of its angry mask locked onto the struggling Shisui. The two giant arms clenched into fists and slammed down toward Shisui!
But at that moment...
"Enma!"
"Wind Release: Wind Blade Jutsu!"
Accompanied by two different low roars, a highly condensed wind blade sliced through the air, and an enlarged Adamantine Staff came crashing down. The giant wind blade carved a trench several meters deep in the ground, cutting through the demon giant's flesh and exposing the bone, briefly revealing the white figure's body.
Boom!!
The terrifying force, powerful enough to send the Nine-Tails flying, not only hit the white figure's body but also instantly sent the crimson demon giant flying backward.
"What are you standing there for?! Have you lost your courage?!"
Hinata Yunchuan's angry roar shattered the Hidden Leaf ninjas' fear and daze. The ninjas present collected themselves and began making hand signs, ready to attack.
However, just as they mustered a bit of fighting spirit.
Whump! Whump!
Two equally massive auras, radiating a terrifying pressure, surged from the other side of the Uchiha compound without warning!
Due to their higher ground, the Hidden Leaf ninjas watched as two more Susanoos appeared. Both were blue Susanoos! Both were in their first form!
Silence!
The sounds of fighting, explosions, and screams seemed to have all disappeared at this moment! The faces of the Hidden Leaf ninjas were all blank with stupor. Their mouths hung open in shock and disbelief, but they couldn't make any sound. Their bodies seemed to have frozen in place, and their blood had stopped flowing. Even Hiruzen Sarutobi was the same.
Four? Four Susanoos? Four pairs of Mangekyō Sharingan?!
Fugaku Uchiha alone was so terrifying, and now two more Susanoos of unknown identity had appeared?
What... what is going on here? Is there really still hope for the Hidden Leaf Village?
Just as despair was about to consume everyone, an unexpected scene unfolded. The two Susanoos in the distance, as if they had seen their sworn enemy, suddenly rushed toward each other and began to fight.
"Lord Third," Hinata Yunchuan said at the right time, his expression filled with shock and uncertainty. He looked at Hiruzen Sarutobi and said, "It's Kakashi, who was taken by the masked man! This is the power of that 'Envy'!"
Upon hearing this, a spark of light appeared in Hiruzen Sarutobi's numb eyes.
Meanwhile, on the other side of the Uchiha compound, the two blue Susanoos were entangled in a fight. Both Susanoos were in their first, skeletal form. Their attacks were limited to simple physical strikes controlled by the Susanoo.
Bang! Bang!!
Dull thuds echoed in the rainy night. The two identical blue Susanoos fought like a street brawl, awkwardly swinging their huge fists at each other. Each collision was accompanied by a "crack" of breaking bones and a massive shockwave, sending them sliding backward for several meters and creating deep trenches in the muddy ground. This kind of pure, brute force hammer-fest, with no strategy, was more of an outlet for frustration than a fight.
"Cough cough!" Kakashi Hatake covered his bleeding eye. The warm liquid continuously seeped through his fingers. The intense pain left his forehead covered in cold sweat. He knelt in the Susanoo, slowly looking up with a complex gaze at Obito Uchiha, who was wearing the spiral mask in the other Susanoo in the distance.
Just now, he was shocked when he realized that the masked man was Obito Uchiha. In that instant, Obito used Kamui to instantly appear beside him. He didn't even have time to react. He just felt a sharp pain in his left eye, and his Mangekyō Sharingan was plucked out by the other man!
Kakashi Hatake, who had now come to his senses, was filled with frustration. If he hadn't lost that Mangekyō Sharingan, he could have worked with the mirror-version of Obito to defeat the real Obito.
"Hey hey, Kakashi, are you okay?"
A slightly frivolous voice rang out in front of Kakashi. Kakashi withdrew his gaze from the distance and looked at the source of the voice. Standing in front of him was another "Obito Uchiha." This mirror-version of Obito was completely different from the grim, masked man. His Mangekyō Sharingan was clear and curious, without a hint of gloom.
"Tsk, he's so ruthless, that me," the mirror-Obito said, looking at Kakashi's bleeding eye socket. He clicked his tongue. His tone was helpless but not somber. "But it's good that you're alive. How are you? Can you still move?"
Kakashi Hatake silently nodded. The blood loss and intense pain had made his face as pale as a sheet, but what shocked him the most was the current situation.
"Hey, that's good!"
The mirror-Obito grinned, showing a mouthful of white teeth, as if the desperate situation in front of him was nothing. He turned his head and looked at the masked Obito in the distance.
"This is interesting. I never thought there would be a day where I had to fight myself."
The mirror-Obito rubbed his chin, his face filled with an eager excitement. His tone was a mix of novelty and mockery. "Tsk tsk, this is something new, isn't it, Kakashi?"
Kakashi Hatake remained silent, only looking at him with a more complex expression. This big-hearted, chatty, and slightly off-the-wall "Obito" was the real Obito. What had that Obito, who wore a mask and brought destruction and death, gone through to become like that?
"Then I'm going... Oh, right, one more thing."
The mirror-Obito didn't seem to mind Kakashi's silence. He went on to stretch his limbs. The carefree smile was still on his face. He suddenly seemed to remember something and turned his head. He looked at Kakashi and asked in a tone of slight anticipation and a bit of embarrassment, "Kakashi! What about Rin in this world? She's okay, right?" He paused here, and the smile on his face faded slightly. He continued, "You didn't, by any chance, kill her, did you?"
Hearing the name "Rin," Kakashi's body stiffened. He instinctively opened his mouth, but his throat seemed to be blocked by something. He couldn't make any sound. Only the pain and despair on his face silently told the cruel answer.
Kakashi didn't know why Obito was still alive, but at this moment, he finally realized that the turning point that changed Obito's destiny was the death of Rin, a death that he had caused. On the battlefield between the Hidden Leaf and the Hidden Mist back then, two of the three of them had died. But the one who lived wasn't a whole person either. He and Obito each lost half of their souls!
Upon seeing Kakashi's expression, the mirror-Obito's smile completely vanished. He scratched his spiky black hair.
"Oh..." The mirror-Obito's voice dropped. He sighed, "No wonder. No wonder he became like that."
"Even though I know it's something from another world, hearing that your wife was killed by your best friend and couldn't be saved... it's still a bit awkward and frustrating..."
In the distance, the real Obito Uchiha's body was trembling. The nails of his clenched fists had broken through his palms from the force, and the drops of blood that fell on the ground spread into a glaring crimson puddle. He didn't know why that "Obito" had appeared, but he felt the exact same aura. He was certain that was "himself," another Obito Uchiha!
An Obito who had also nearly died at the Kannabi Bridge but had not had the symbol planted in his heart by Madara Uchiha! An Obito who had not only not lost Rin but had also ended up with her, an Obito who had fulfilled his initial dream of becoming Hokage step by step!
But... in the mirror-Obito's almost perfect reflection, Obito Uchiha seemed so ugly at this moment. It was a painful sting to the real Obito Uchiha.
"Why?"
He stared intently at Kakashi Hatake and "himself" in the distance. Obito Uchiha's murmur was low and hoarse, and his crimson Mangekyō Sharingan's hatred grew deeper.
"Why?!" he roared.
Why is it you?! Why isn't it me?!
The mirror-Obito pulled his gaze away from Kakashi. His eyes flickered with a complex emotion as he looked at his other self. He then smiled and said, "Stop. You still have a chance."
"Hahahaha!" Obito Uchiha took off his mask and revealed a grotesque, hateful grin. "You who haven't lost everything, what right do you have to lecture me?!"
This flawed world... should just be destroyed after all.
In the world of the Infinite Tsukuyomi, I'll get back everything I lost!
"In that case," the smile on the mirror-Obito's face faded. He took off his Hokage hat and said in a deep voice, "I'll have to beat the mad 'me' back to my senses!"
The two pairs of identical Mangekyō Sharingan stared at each other, but their eyes reflected two completely different emotions. Hatred, and pity.
The next moment, flesh and blood grew on the bones of both Susanoos. Both of them simultaneously activated the second form of Susanoo, raised their fists, and smashed them at each other!
Boom!!
