Toshiko was sleeping. Isshiki was staring at Toshiko's head on the ground at the corner of the room they were in. He was deep in thought.
Isshiki was contemplating his future plans after destroying Kagaku, the world tree takes time to grow and considering the aggression that he would face and his condition he would have to speed up the growth of the tree, lest it be disturbed by the natives.
'I wonder if Kaguya survived, she would be ideal nourishment for the tree. Of only Toshiko would tell me more.'
Isshiki grabbed Toshiko's head and walked to the door. He reached forward and began sliding the door right whe-
A giant laser shot from the sky.
And another
and another one.
From various angles in a millisecond orbital lasers shot from the sky pointed at Isshiki.
An explosion bigger than the largest mountains erupted. A blazing fireball of pure heat from the light appeared. The atmosphere those lasers passed through ignited and expanded. Shockwaves and explosions permeated and covered the radius around Isshiki for Miles.
Seconds passed and a mushroom cloud rose to the sky.
The rumbling sounds of earthquakes hung I'm the air as the piercing white light of the lasers dissipated.
Up above, the clouds in the sky had large holes from where the lasers had shot.the ground below was glassed, it was reduced to flat ground and rubble where nature was erased and the ground glowed with heat.
Isshiki appeared from a portal back to burned crater. His face was burned beyond recognition, Isshiki's lips were gone and his eyelids were burned to a crisp leaving only his distinct eyes on a black charred face.
Isshiki was heavily breathing and in pain.
He had barely reacted in time. Moving into his pocket dimension to avoid annihilation. The nuke he had previously faced when coming to earth was exploded within his proximity, he had time to suppress it. This time he barely had any, and he was at the center of it.
In Isshiki's hand Toshiko was fine with only singed hair. Isshiki's hand that carried Toshiko's head just barely entered the portal in time, compared to Isshiki's face.
"Isshiki Otsutsuki."
Mitsuo walked out of a portal confronting Isshiki.
"Look down!"
Mitsuo pointed downwards with vigor and Isshiki glanced down in anticipation of an attack.
Above Isshiki a rod of tungsten the size of a building that was just in orbit fell onto Isshiki's head from a portal
But Isshiki dodged to the side.
He shrunk down and reappeared right next to Mitsuo with an attack while Mitsuo was already throwing a punch at Isshiki, his shrinking innefective for stealth.
A black rod sudden appeared and shoved itself through Isshiki's head killing him. Ending the exchange in an instant. Although injured Isshiki had maintained his incredible stats from his Otsutsuki body and chakra quantity.
But then thousands of portals appeared above. From each one humanoid robots flew out. And one of these robots was another Mitsuo.
'clones?'
Mitsuo's augments were not special, at least not to the inventory. It could easily recreate his cybernetics and clone his biology and memories to create an exact replica. Mitsuo just like Mikitaka found being replicated through technology uncomfortable and avoided recreating himself. But this was the exception.
All of the Mitsuo's began charging at Isshiki. In response a giant cube appeared and fell from above, all the Mitsuo's chose to self destruct simultaneously. And another nuclear explosion of epic proportion was set off.
Isshiki came out of a portal again. He immediately activated his Byakugan as hundreds of Mitsuo's came out of portals all around, each one just as real as the other and willing to die.
Isshiki held out Toshiko's head straight forward. And a black rod appeared, inserted into Toshiko's head to forcibly activate his shinjutsu and speak the words.
"Infinite Izanagi"
Reality exploded. The ground shattered and seperated, revealing a starry sky beneath. The sky fractured and tore apart, revealing more stars. Their fractured surroundings were like islands of rubble in an ocean of stars, galaxies, black holes, and planets. All visible at varying distances and sizes. An unrealistic depiction of space, more like a model of one, scaled up for visibility.
"Domain Expansion: Event Horizon"
Toshiko's eye's were wide open, tears of spinal fluid flowed down each of them. They no longer simply looked like the senrigan with a crescent moon shape and dot in the middle. It glowed and projections of shapes formed in front of his eyes in layers. Simple geometric shapes, tomoe, clocks, or bizarre organic shapes. They all shimmered and blended together in a tapestry of raw beauty. It was the system. Toshiko had harvested the system itself and made it his Dojutsu for this domain expansion.
Isshiki spoke up. "I believe your name is Mitsuo. You have many powerful weapons but unfortunately, I have this." Isshiki let go of Toshiko's head, it began floating off into the void of his domain. "This domain will block you off from the dimension your clones have been coming from. And if I kill you here, you will die regardless of how many clones you have outside of this domain."
It was true, the power of Infinite Izanagi had forcibly merged the hundreds of Mitsuo's together and crystallized the concept of Mitsuo into that body ensuring that when the domain cancels the destruction of Mitsuo would ripple out and destroy all other Mitsuo's in the inventory.
"You're not very good at this are you?" the combined Mitsuo stood still. He was looking at his surrounding like it was an art gallery, measuring each minute detail.
"There's no reason to tell me about the effects of this ability."
"I'm simply being polite. You may have noticed but you should be much stronger than before. That disgusting traitors shinjutsu makes it so that everyone within its effect is amplified in strength." Isshiki made an ugly expression as his eyes pointed at Toshiko's head which was aimlessly floating off in the distance.
"..."
"Within this domain I am restored. And now I will kill you"
Isshiki was no longer in a weakened state. And although Mitsuo's power was multiplied by the hundreds thanks to all his merged selves. It was nowhere near the planetary power of Isshiki."
Mitsuo looked up at the starry sky this domain had. He raised his hand and rubbed down his face with one exhausted stroke. He was completely unfocused on Isshiki and just looked at the celestial objects surrounding him. And then he looked back at Isshiki.
"Thank you. I've always loved space you see."
And they fought.
