Crom: I didn't expect you to know my name.
Sparda: I know a lot of things.
Katarea was fuming because Sparda called her an insect, but she had heard about his power so she was not sure what to do but finally her ego won over her common reasoning.
Katarea: How dare you call me an insect even though you are a pure Lucifer you are supporting the current devil kings what a disgrace.
Sparda: Just shut up, if you live we will talk about this later.
Sparda said that and released a huge amount of power from his body. The power was definitely of peak Satan class level. Sparda kicked the ground and punched Crom Cruach. He guarded against the attack but he was blasted away from the room making a body-sized hole in the wall. Sparda also jumped out following him.
Crom landed about 30m away and Sparda landed in front of him.
Crom: I didn't expect your punch to have so much power.
Sparda: Well I am full of surprises.
After Sparda said that, both Crom and Sparda kicked the ground and started to fight in hand-to-hand combat. The ground beneath them started to crack as they were fighting. Crom was the best hand-to-hand fighter Sparda has ever fought. He was able to keep up with Sparda. Sparda covered his fists with demonic energy and Crom also did the same but with dragon energy. Whenever they both had any contact a shockwave would form.
Sparda saw from the corner of his eye as to how the other fight was going on and saw that Katarea was losing. Sparda stopped attacking Crom and jumped backward to make some distance between them.
Sparda: Aren't you going to help your friend??
Crom: She is not my friend. I don't care if she lives or dies, I only care about our fight.
Sparda: Well said you are definitely in the top of my favorable people list.
Crom: Thanks I am so flattered, so why don't we kick up the fight by a notch.
Crom didn't wait for Sparda's reply and directly transformed into his dragon form and spits fire where Sparda was standing. Their school was also caught up in the fire and it was completely destroyed. The whole surface beneath Sparda was transformed into molten lava. Tia's flame was not even comparable to Crom's flame. Sparda saved himself by forming a space barrier around him.
Sparda's eyes changed into EMS and a dark purple aura started to cover him.
Sparda: Susanoo
After saying that Sparda was being covered a skeleton which soon was covered by muscles and soon by Chinese armor it had 4 arms and fire was burning in place of its eyes. It had 4 swords tied to his waist. It had a gem on its forehead in which Sparda was standing proudly. It was standing tall by 50m which was a little bit smaller than Crom's dragon form. Everyone except Azazel, Vali, and Tia were shocked seeing the towering giant.
Crom: I have never seen any power like this.
Sparda: I told you I am full of surprises.
Sparda didn't wait for Crom to prepare himself and attacked him. Sparda punched Crom in his face and was about to continue punching him when suddenly the surroundings changed to normal. Sparda got slightly distracted because he wanted to check on Sona, Tsubaki and Akeno's condition. Crom takes advantage of this moment and makes some distance between himself and Sparda.
Crom: Why are you holding back??
Sparda: I was just having fun fighting with you and if I use my full power you will die.
Crom: Honestly I didn't think that the difference between us be so huge, so the rumor was true you being in the top 3.
Sparda: So why did you decide to show yourself??
Crom: Ophis told me about your existence so I wanted to check out for myself so here I am.
Sparda: Ok that is enough now let's continue.
Sparda and Crom were about to resume their fight but they were suddenly interrupted by a sudden burst of power. Sparda was really amused to see that the power belonged to Issei, Crom also stopped and looked towards them.
Sparda: Do you continue our fight?? I have lost all interest.
Crom: You are a lot stronger than me it is insulting but I am no match for you.
Sparda: So let's see their fight.
Sparda deactivated his Susanoo and started to spectate the fight of Issei and Vali. Everyone was shocked seeing that Sparda let go Crom and was now standing beside him watching the fight between Vali and Issei. Vali used a move called Half Dimension and Issei was tipped off by Azazel that the move Vali used will divide Rias's breasts to half of its size. Which helped Issei to release a huge amount of power and he was able to strike down Vali to ground.
Vali was about to activate his Juggernaut drive but Sparda decided to intervene.
Sparda: Brother you should stop look around you if you activate that here a lot of innocent humans can die.
Vali: Ugghhhh... Ok. Issei train harder and grow stronger, next time my brother won't be there to save you.
Sparda: So who won the Butt-dragon emperor or Boob-dragon emperor. You were fighting to prove the superiority of Boobs over Butts and vice versa right??
Vali was enraged by what Sparda said and Azazel was rolling on the floor laughing.
Vali: Wha---What are you talking about??
Sparda: Oh you know very well what I am talking about.
Vali was about to retort but suddenly the barrier broke around them and Bikuo dropped from the sky and took Vali with him and Crom also teleported away.
Sirzechs: Why did you let an evil dragon escape??
Sparda: If we have fought here seriously the barrier would easily break and innocent humans would be involved. There would be a lot of collateral damage. We fought for a little bit and see what happened this whole place is destroyed.
Micahel: I have to agree with him Sirzechs, he is right.
Azazel: Sparda are you ok??
Sparda: Why shouldn't be I ok??
Azazel: I meant your brother betrayed us.
Sparda: Well he must have his reasons.
Michael: Sparda if you are free would you mind coming with us to the heaven tomorrow??
Sparda: No, no problem. I would really like to visit there.
