"Soul Multiplicty: Body Repel," a fleshy mass is quickly expelled forward art extreme speeds knocking Itadori full force and grazing Nanami. Mahito then used the time gained to create proper soldiers with polymorphic soul isomer.
He was interrupted after the third by Kaichi with Nanami just behind. So Mahito turned his arm into a blade, making it look like a direct confrontation, only from it to turn soft and wrap around the blade and pull Nanami closer. Only for Yuji to come flying in after being tossed forward by Junpei's shikigami, punching Mahito into the pavement.
The shikigami and Kaichi quickly retreated back to help with the polymorphic isomers, Nanami, now free begun ganging up on Mahito, knocking him back and forth between him and Yuji, tired of this Mahito turns into a giant ball of spikes.
This doesn't really work as his mass became so spread out that it barely did any damage, but it did push them back. He then charged and went for the back line, Junpei and Ino, who were still busy fighting the Isomers so Mahito got the drop on Ino hit him with a giant fist, knocking him back and into a wall.
Junpei was next and he got hit with three serrated whips, unable to defend himself with CE as he was still newly awakend and his shikigami was busy fighting the isomer. Junpei took the attack full force, getting his arms shredded and mangled in the process.
Mahito moved in to finish the job but his luck ran out and Yuji had caught up, clocking him in the back of the head, stunning him for long enough to get Mahito back into a combo between him and Nanami, only this time joined by Ino, channeling Kirin now, as kaichi finished off an Isomer and was distracting another while Junpei's shikigami was still fighter the last one.
Mahito could no longer handle it, and in a moment of inspiration managed to use Domain Expansion: Self-Imbodiment of Perfection, it didn't last long however as Mahito was dragged into Sukuna's mind. "How dare you touch me," was all Mahito heard before he was cut all over.
He quickly canceled his Domain Expansion and retreated by quickly shrinking down to a child and making a getaway. The rest were temporarily stunned by the sudden appearance and disappearance of a Domain.
Mahito wasn't able to get far though as he was suddenly impaled by a spiked bone and pinned to the ground, at the moment of impact he saw phantoms of all the people he had harmed and a sudden ethereal weight pressed upon him. He managed to remove the bone quite easily, but what concerned him was that the weight hadn't gone away and more pressingly, he wasn't healing as quickly.
"How's it feel? To have your sins crawling on your back." Everyone's attention turned to the origin of the voice and saw Sans, standing over Junpei, with a hand on his shoulder, his hand and Junpei were enveloped in a weak green light as his wounds slowly stitched back together.
He was using a combination of Green and RCT to heal him. Yuji was about to move towards Sans when Nanami stopped him, "Don't worry, he's just healing him," he eased.
"What did you do?" Mahito asked with a growing concern as his his body continued to follow his soul on a delay.
"That's easy, it's called Karmic Retribution, every attack I make carries it, a sort of poison to the Soul," Sans finished healing Junpei who stared at his arms then Sans in slight amazement. Sans then gestured towards Mahito as he began walking closer and Mahito's Soul appeared in front of him.
It was and upside-down gray heart, but unlike a normal Soul, this one had a purple crack on it that grew for a moment before disappearing, leaving the crack behind.
Mahito noticed with the disapperance of the purple did the weight finally lift but the delay was still there. "What is this?" Mahito was even more concerned now, staring at his Soul.
"It should be obvious but that is your Soul, not the kind you manipulate but the anchor between it and the body. And Karmic Retribution only works on those with serious sins, so you must have been quite the naughty Curse." Sans then summoned a volly of bones and a line Gaster Blasters behind that.
"I've seen enough of your work and I'm tired of it, so burn in hell." The bones shot out at sonic speed nailing Mahito to the ground once again. The Gater Blasters were fully charged, "Die."
The Blasters fired, obscuring their impact, the shear power the Sorcerers felt from the blast was terrifying. When the dust settled what appeared before then was not the remains of Mahito, but a ball of tree scorched and crumbling tree branches.
The branches crumbled away to reveal a tall crouching figure with branches coming from where it's eyes should be. "Oh, another one, this could be interesting but I'm really pissed off at the moment so let's end this now, Domain Expansion: Judgment Hall."
A 20m Doamin expanded, encompassing everyone present, the Domain appeard as a golden corridor within a underground castle. Everyone quickly noticed the effect of the Domain with Nanami, Yuji, and Ino gaining a all around spike in power and an increase in amount of CE, while Mahito and Hanami feeling weaker and a decrease in CE, and Junpei a smidgen of an increase In power and CE.
"I said," purple bones shot up to the ceiling in a circle around Hanami and Mahito as a giant orange Gaster Blaster charged up above them, "Die."
An almost deafening sound erupted as the Blaster shot forth, Hanami created a quick wooden shield while reinforcing herself with as much CE as she could and coverd Mahito, while Mahito reinforced her with his own CE and reinforced her soul as much as he could.
The Blaster didn't even slow as it eviscerated the tree shield, and bathed Hanami in orange light. Hanami was barely holding on for the first 5 seconds before she felt herself being eviscerated, her arms slowly turning to dust.
Then from Hanami's shadow a darkness extended and quickly enveloped both Hanami and Mahito before disappearing. To the outside observer it looked like they had died, but Sans saw it, or didn't see in this case as their Souls didn't shatter but disappear.
The beam finally died down, allowing the Sorcerers to hear again, Sans desummoned the bones, Blaster, and his Domain. "Did you get them?" Nanami asked as he looked back at Sans.
"No, someone else managed to step in and escape with them before I could react, they're still out there." Sans said as he sat down, he was tired, teleporting so far and frequently with others, while also healing everyone affected by Junpei's poison was so tiring.
Plus that was his first time using his Domain with such a big attack, all this back to back, he definitely earned a nap. A *meow* came from his hoodie as the kitten from earlier stuck it's head out, "Sorry about that little girl, didn't mean to wake you." He apologized as he reached up and pet it to calm it down.
