In the airspace of the Underworld, planet shaking battles took place. Baldur, and Vidar had already been killed, while Apollo, Athena, Hera, Shemhazai, Michael, and Barakiel had all been incapacitated. Akeno was still fighting with Freya. She had large cuts on her priestess outfit, while Freya lost an arm. And Asia, Riser, and Gabriel were still fighting Enma and Vishnu.
Vali was supporting Kuroka by letting her lean on his shoulder. They were about to block yet another world shaking blast from Kokabiel and Raphael, when suddenly, everything stopped. Kokabiel and Raphael stood still in the air, their attack also stopped moving, making it look like they were posing.
Vali and Kuroka weren't frozen, they watched with disbelief as Chojusen appeared out of thin air and directly canceled the attack, that would have blasted them for kilometers, with ease. Chojusen had on his traditional white ninja armor and a small black dragon was by his side. Chojusen's personality had shifted dramatically after coming out of the fusion. He chose to not directly eliminate his enemies and instead only froze them in time and space. After collecting Kokabiel and Raphael into his personal dimension, he looked at Vali for an introduction.
Seeing the enemies presumably die, Kuroka stopped fighting against the Sage Seal and let it ravage her body. The longer she held on her False Sage form, the worst the backlash would be when she stopped resisting; she just hoped to be alive after the backlash ended.
Immediately after the Sage Seal on her forehead disappeared a soul crushing pain passed through every part of her body; no cell was spared from this pain. She screamed like a banshee and bit her tongue to not go unconscious. From the outside everyone could see her fair white skin turn red from all her pores exploding into liquified blood.
Chojusen didn't know who this lady was, but she was fighting alongside Vali against his enemies, so he summoned a sphere of water to hold Kuroka. Within this ball of water, all Kuroka's injuries healed at a ridiculous 10,000 times the normal rate. However, this was the backlash of breaking her Sage Seal, so the damage could not be so easily erased with just a water healing.
Only after Chojusen entered Water Elemental Sage Mode did the effects of the backlash start to disappear. After the backlash finished acting on her body, Kuroka fell out of the water sphere powerless; more than 90% of her power had been sacrificed to reach the peak of Super Class.
Vali caught Kuroka, prompting Chojusen to ask "So who is this woman?"
"She's..."
Vali was about to continue, but Koneko managed to jump in and say "She's my sister Kuroka." Then took Kuroka off of Vali and held her up.
Chojusen said "Oh? I didn't know you had a sister. Why didn't you invite her to the training in my dimension? Now that I think about it, you've never mentioned her before..."
"She… became a stray devil after getting drunk on Sage Ar..." suddenly, Koneko realized that Chojusen just used Sage Arts to heal her sister. Actually, Chojusen was still wearing his Water Sage Cloak. Koneko gave Chojusen a puzzled glare and said "You… are a Sage?"
"Huh? Yeah, what about it?"
"My sister… I was told that she got drunk on her power and then killed our previous master. But, she told me that was not the case and seeing how you are nothing at all like they said a person would become after mastering Sage Arts, I don't know what to think..."
Kuroka might be powerless, but Chojusen's healing let her walk and talk like normal. She said "It's the truth!"
Chojusen could tell if demigod were lying to his face, to say nothing of a weak Kuroka. He took Koneko's hand and asked Kuroka "What happened?"
"That… Bastard. He wasn't content with using me and the rest of his evil pieces for experiments. There were days where he would force us to eat and drink acids just to see how we would react… When Koneko's abilities as a Nekoshou started to appear, she entered his eyes as a good candidate to experiment on.
I pleaded and asked him to do his worst on only me, but he wasn't satisfied… When he dared to take Koneko from our room one night, I caught him before he did anything Koneko. She didn't see anything because that bastard used something to keep her knocked out."
From Kuroka's body only the white glow of sincerity could be seen. There was also a bit of brown indicating that she still felt awful about those incidents of the past. Everyone who came into contact with the Essense Sensing Skill understood intuitively what the colors of a person's emotions meant. Thus Koneko, understood that her sister hadn't been the horrible person she thought she was. She finally stopped hiding her true Nekomata form and two white cat ears as well as a tail appeared on her body.
Koneko started crying and gave Kuroka a heartfelt hug. As Chojusen released Koneko, he healed Vali back up to normal with Temporal Restoration, and Yang Rebirth. Off to the side, Kiba, now holding a demonic holy sword, and Bikuo approach Chojusen. Chojusen said "I'll be taking us around to end the war now..."
No one really knew what he was talking about, but after seeing him stop Super Class beings somehow, they followed through to see what he would do. Chojusen covered everyone with his energy and teleported to pick up Rias and Gasper. They had still been fighting with a never ending stream of King, Emperor, and Satan Class enemies.
When Chojusen appeared once again, all the enemies were frozen just like Kokabiel and Raphael; this was an army of millions of legendary beasts, Valkyries, reapers, phantoms, and other mythological beings. With the snap of his fingers, the entire army disappeared into his personal dimension.
Rias gave him a doubtful glare and Gasper marveled at his comically exaggerated spacetime powers. The three shared a couple bits of information, before Rias and Gasper joined Chojusen to another location.
The next place Chojusen appeared at was besides Akeno. After putting Freya in his personal dimension with the same process, Chojusen healed Akeno, received a kiss, and teleported to Asia's battlefield.
Riser, Asia, and Gabriel were still in the heat of an epic battle. There were clearly bits and pieces of mountains left from all their fighting. However, Chojusen's newfound divinity made him unstoppable; at least up to the Super Class. He froze Enma and Vishnu and sent them away before meeting up with Asia.
As he healed his allies, he asked "Hey who's this woman?" He pointed towards Gabriel.
Asia said "She's Gabriel an Archangel of Heaven who came to help us in the war."
Chojusen was a bit confused because he had stopped several thousand pure and fallen angels when he went to pick up Rias and Gasper. After Asia explained that only some of the Angels and Fallen Angels defected to fight on the enemy side, Chojusen understood and introduced himself to Gabriel.
He heal all three of his comrades, but Riser was still a bit nervous around him. Asia noticed their odd exchange and said "You should thank Riser, if it weren't for him I might have died."
"Oh? Really?" Chojusen asked asked Riser.
Riser began to start sweating. He shook his head and said "It wasn't that serious..."
"You took a divine spear to the chest." Asia was a bit too straightforward.
Chojusen gave Riser a pat on the shoulder and said "Seriously, you should stop fearing my like we're still enemies. Just treat me like the brother-in-law I will soon become."
Riser gave no comment, but at least he stopped acting like Chojusen was out to get him. He made one final teleportation in the Underworld to pick up the remaining Super Class beings that had either been crippled, or had fled to recover. Chojusen updated his group once again and then unleashed his divinity to search for all the demigods.
Another term for complete divinity was True God, which just so happened to be Chojusen's current level according to the system. At his currently level of power, his teleportation range could see through everything within the Underworld and still have the strength to check other dimensions.
It didn't take long for him to find what he was looking for as the shockwaves of demigod battles could be felt from his personal dimension. He was prepared to teleport to whoever needed his help the most, but everyone on his side was winning their battles smoothly. After Ino and Lee killed off two gods, they returned to the battlefield to help their comrades.
With the advantage constantly increasing as they helped kill or cripple more and more demigods. By the time Chojusen came to their help, the only remaining people from the enemy side that were still fighting were Great Red, Indra, Shiva and Sun Wukong and all of them were being miserably beaten.
