Kyuu was formed during the battle with the human in a semi-Multiverse event that reunited the multiple variants that form him and a few others. He's extremally powerful and in a start the human stood no chance against the might of the fusion but after many hours of fighting Kyuu and his two teammates, Decadent and Hardmode were at limit and about to loose until the human got distracted which was instantly answered by Decadent attacking them. The battle continued until various elements from his world started to disappear. And Then, looking all around they see two skeletons, one with four arms and one with a colorless outfit. The human moved swiftly trying to kill the two newcomers until they were frozen in place by the colorless skeleton, until the human were wiped from existence. For a few seconds everything was quiet until the world started to shake so suddenly. The Four armed sans yelled at the group to follow him to keep living. When they got to the throne room there was a rectangle of static and the four armed skeleton jumped through and with no second thought Hardmode went through. Decadent and Kyuu hesitated for a few seconds and looked behind them to see nothing but void. And then jumped through in the nick of time, when they got through the portal flickered and suddenly closed. Kyuuseishu and Decadent got up to see Hardmode and the four armed skeleton talking to eachother. They came closer and Kyuu got a bad feeling to only became more intense. They all talked to each other and stablished the name of all them. Being Righteous the colorless one, and Goddkira, who was created by Righteous. And then Kyuu suddenly understood why he had that feeling and it was because Righteous high LV, and just like the human; Kyuu, as the judge, summoned his gaster blaster to give righteous the death sentence. Everyone was surprised at Kyuu's actions but before anyone could do anything a long red bone spear come and destroyed the attack. Everyone looked over to where the attack came from and to the shock of Kyuu it was Papyrus, he walked over and looked at each of them, telling everyone, but Righteous, and Goddkira, that attacking the people who saved wasn't a good way to greet. Before Kyuu could respond papyrus made a gasp sound and suddenly picked up Kyuu asking if he was hurt or not. Kyuu with all the memories of his past papyrus a great emotion shocked him and then. Papyrus, showing its hospitality, put Kyuu on his shoulders and took him to the bathroom door so then he can clean up and so Papyrus could fix his clothes. Shortly they made it to the bath. Papyrus drew him the bath and leave him in there to clean the blood off of his bones. It took a while but after finishing he took a towel and walked out where papyrus was sewing and trying to repair his clothes. Papyrus greeted him and gave him his new clothes, Papyrus had to use his sleeves to repair his jacket but he found a solution by using some white cloth he found to make him new sleeves, Kyuu tryed (and failed) to not cry in front of papyrus again. Upon seeing his state Papyrus comforted him and promissing that everything would be ok. After a long time, Kyuu was able to compose himself and realize his mistake. He went to go to apologize to Righteous but when he went to his room he was completely out from there. Going outside found Goddkira with the other two building something. Kyuu apologized to Goddkira and proposed a deal with him. If he helped to build the home on where they will be staying in and if Righteous forgave him he'd forgive him too. He agreed to the terms and started working on the house. It felt like hours but they managed to get the house done and in that time Kyuu, Decadent, and Hardmode made an agreement to stay in the NULL with them. Goddkira soon came with Righteous to see the new home. Kyuu tried to explain and apologize until Righteous stopped him and forgave him on the spot. Turned out that Goddkira explained everything to him but he finished with a condition, all three of them nodded in agreement creating the group called "The Executioner Faction"
