Cao Cao: Georg release all of the Samael's bounds.
Georg didn't say anything and complies with his given order and Samael is freed from all restraints. Samael didn't look anywhere and directly attacks Issei and Vali with poison. Hela tries to stop Samael but its attack was too fast for Hela to stop. When Hela was able to stop Samael he had already scratched Issei and Vali. Samael used his tongue to attack both Issei and Vali which was still sticking out of its mouth. Hela grabbed his tongue and ripped it off.
Issei and Vali were already on the floor and they started to scream. Hela was worried that she was unable to stop Samael from attacking Sparda's brother so he might hate her. Scathach was also thinking the same. Hela was completely enraged and she tore of Samael's both arms. He tried to fight back but it was useless against Hela. She started to punch him breaking almost all the bones in his body but he was still alive barely. Hela was furious which made her think that he was already dead since he had stopped moving. Hela was about to attack Cao Cao and Georg but before she could move both of them disappeared into purple mist leaving the rest of them in the underworld. The enemies who were left behind they were sure that they would die today.
Issei was being attended by Asia, Katase, and Gasper. Whereas Rias was giving Vali a lap pillow while the Vali group was standing around them. Scathach and Hela released their full power on the enemies. They were about to attack the rest of the enemies but suddenly Samael got up and launched himself in the direction of Ophis. Even though he was injured he was able to heal himself because of God's curse though he was unable to heal his lost limbs.
~AT THE BATTLEFIELD~ (A few minutes earlier)
Sparda was standing in front of Great Red because she was stopping him from killing Ophis.
GR: Stop trying to kill her.
Sparda: Why should I??
GR: Even though you changed the reality that no longer her aspect of infinity exists it will still come back to her.
Sparda: Then move aside I need to kill her quickly.
GR: If you kill her another infinity will appear who might be evil.
Sparda: That is a chance of might and next infinity might not be stupid like this one.
GR: But I cannot let you take that chance.
Sparda: You were supposed enemies a few moments ago.
GR: She might hate me but I will not let you kill her.
Sparda: Try and stop me.
GR: Than it leaves only one option for us.
GR didn't say anything and starts to release pressure and Sparda also releases his pressure. The whole world was shaking by the amount of power they were releasing. Soon GR's power started to put pressure on Sparda but he was still sure that he could win against her as long as he has VM. Because both of them were releasing so much power they were unable to notice that Dimension Lost's barrier has collapsed and Samael was heading towards them.
Suddenly GR side-stepped on her pure instincts and she dodged Samael but Ophis was not so lucky and Samael bit Ophis on her shoulder. Sparda was confused about what was happening and looked towards the separate dimension's direction and found that Vali and Issei were injured. He put 2 and 2 together and understood what has happened. Rage took over him completely and he kicked the ground and reached Samael and started punching him with his full power. With every punch, he would make a hole in his body but it would heal.
Sparda had enough of this and decided to end the fight. He started to change reality where Samael could be killed. After using a lot of power he was able to achieve that and then he touched Samael's body and used VM. Samael's body completely disintegrated into thin air. He again looked towards GR who was now holding Ophis. Sparda used VM and moved at blinding speed towards his brother. Vali had already passed out due to pain.
Sparda sat beside Vali, Sparda was breathing heavily because he had a huge fight and he used most of his power to change realities. He had already used Reality Bending three times but if he wants to save Vali then he needs to change the reality again. Sparda starts to gather his remaining power and starts to bend reality. Soon Vali opened his eyes and Sparda dropped on the ground because he had used all of his energy.
Vali: What happened to my brother??
Rias: Your brother saved you but in return, he used all his power and lost his consciousness.
Hela, Scathach, and Kali came back after they killed all the remaining enemies. They came back and saw Sparda was unconscious they immediately ran towards him and started to check him.
Kali: Thank God he had only tired himself out.
Scathach: Vali you are ok??
Vali: Yes my brother healed me.
But Rias was worried because Issei was still infected by the poison and Vali group. After all, they saw that Ophis was infected too. Suddenly GR appeared beside them while holding Ophis.
GR: I like that brat give him to me I will heal him.
Everyone was shocked by GR's sudden appearance.
Rias: Excuse me but I don't know you.
GR: All of you know me usually all of you refer to me as Great Red.
Everyone's mind shattered like glass except for Hela, she already knew who she was. GR looked towards Hela.
GR: You are back good for you.
Hela: Sparda saved me.
Rias: Are you sure you can save him??
GR: Who do you think I am you skank??
Rias: Me—Me a skank??
GR didn't reply to her and grabbed Issei from Asia's hand and opened a tear to Dimensional Gap to jumped into it along with Ophis and Issei. Rias was still contemplating over GR calling her skank.
Akeno: So what now??
Hela: We should head back and enjoy our time of peace. They had huge casualties today so I don't think that they will attack soon.
Azazel: I agree with Hela here. You kids should enjoy this time all of you have earned it.
Sirzechs: So what about Vali and his group??
Scathach: Of course they are with us all charges need to be dropped.
Ajuka: We will see to that.
Vali: Please forgive me and my group if we have caused any problems for any of you.
Azazel: Brat don't worry, all of us make some mistakes.
After that, all of them started teleporting off to their own homes. All of them had a long day and all of them deserved some rest.
