---------------------
While Issei was inside the Match. Outside There were a lot of Devils of Old Satan Faction attacking The Rating Game site. Serafall, Sirzechs and Other Maous with Odin and Azazel were also fighting. Although They weren't that much strong but due to their numbers they were still giving a good fight.
Griselda, Gabriel were also fighting along with other girls including Tiamat. The only ones who weren't fighting were Rose and Ophis.They were just standing as Rose was looking at other girls progress and Ophis was standing eating a chocolate in her hand while also seeing how much the girls have progressed.
Rose was not allowed to use her powers and not that she even needed to. She could kill these levels with only her aura but it would just cause the Dimensions of this world to break apart. Ophis just doesn't wanted to use her powers as Issei told her not to.
Gabriel was easily eliminating the Devils attacking them due to being a Seraph and Using Light element. Griselda, Irina and Xenovia were also using their swords with their Light element to fight.
Rias was using her power of Destruction, Kuisha was also fighting using her Power of Hole to absorb attacks coming towards her. Misla was standing with Lady Sitri and Venelana who were being protected by their respective Families. Although they could also fight but Zeoticus and Lord Sitri didn't wanted them to.
Le Fay was also fighting with them using her White magic and Other magics to fight. Raynare was also fighting along with others. Many of the Devils were targeting towards Asia so Akeno, Shuri and Akari, Sara were there to protect her as she was using her Twilight Healing to treat others. Kuroka was with Koneko. As they were fighting an certain someone attacked Azazel and said
??? : You other races should all just die. We have the Real Maou's Bloodline so we should Rule the Underworld and the whole world"
Other have recognised him as Sirzechs and Azazel stopped their attack and said
Sirzechs :"So you are also here, Cruzerey Asmodeus. "
Cruzerey :"I don't want to talk to a pretender who is going to die today. "
Sirzechs didn't say further as he started attacking him but he had already consumes Ophis' snakes to increase his power. While there were fighting others also continued their fight with others Devils. There were also some Ultimate class devils among them. Odin and Rossweisse were also fighting with others. Tiamat was also there.
After sometime Sirzechs use his orb of destruction towards Cruzerey's stomach to detach the snake from his stomach due to which his power decreased and Then Sirzechs again used his orbs to completely disintegrate him. After seeing that their leader is now dead The Old Satan's devils tried to run away but were still being killed Sirzechs and others.

MC's PoV
??? :" Let me see how powerful you are. "
When he said those wordsand was going to attack me, he saw me smiling as I said
Issei :"So you are finally here Shalba Beelzebub. "
Shalba :"How do you know my name. "
Issei :"Well I know many things but you don't need to know about it. "
After this he didn't say anything as he fired a light beam towards me but I dodged it and I attacked him with my fireball. Seeing my fireball coming he immediately summoned some bees and used them to form magic circle as they fired Demonic power towards me.
When they clashed he immediately used other bees to create different magic circles as they fired a huge amount of demonic power towards me. I also fired many huge ice lances towards it to counter them. After this I attacked him with my
[Crystal flame spear]s which passed his demonic barrier and injured him on his shoulders. After this he didn't wasted time as he ate Ophis' snakes. Then he said
Shalba :"Now it is time for your death. "
As he said this he used many bees to create a large magic circle as he fired a vast amount of Demonic power towards me he also fired light beam towards me at the same time. I used my [Crystal Earth sheild] to protect me.
I was also talking to Ddraig at this time as she said
Ddraig :"Issei aren't you going to use the Boosted gear. "
Issei :"I will use it sometime when I need. "
After this I fired [Icical Lava nails] towards him. Then I used [Burning slash] and [windslash ] towards him. he got injured a bit due to this. But he again attacked me with his magic. But I again fired a fireball and moved from there using my wings.
After fighting for sometime against him, I used my [Fire Dragon God's Breath ] towards him as bees around him got on flames by this. After sometime when the flame subsidized he screamed.
Shalba :"I WILL KILL YOU. "
Issei :"You are welcome to if you can. "
He immediately moved towards me and started attacking me using an outburst of different elemental attacks. I also used my [Fire Dragon God's Breath] to counter it.
Then I summoned the Red Gauntlet and used Boost on myself
BOOST!!
Then I used my Claws to attack his his stomach but it wasn't enough to cut the snake inside. As he again jumped backwards and attacked me using a large amount of Demonic energy. I stabilsed my self and fired my [Fire Dragon God' Roar] towards it. After they both clashed he again shot towards me and attacked me using his hands this time.
After fighting for sometime, I summoned my Demonic Sword and released it's Aura. I know that his powers are nearly equal to the Real Beelzebub after eating Ophis' snakes so I know that he is not weak. Whem he felt the aura for the Sword he said
Shalba :"Wh-What is that sword? "
Issei :"It is a Demonic Sword which contains an Aura of a powerful Demon. "
After this I didn't explained further and started attacking him. I used Boost to again multiply my powers.
BOOST!!
I also used my Fire Dragon Claws to injure him.After Boosts their power has also been increased in dealing damage. He also fought me using all his power as I was also getting many injuries in our fight.
After sometime I again used my claws to attack his stomach and cut the Ophis snakes which decreased his powers instantly. Then I said
Issei :"So now let's end this. "
Then I attacked him using my Demonic sword. As it was going to cut his throat a lance appeared stopping it as a space tear opened near Shalba.Seeing that I understood who it is, So I said
Issei :"George, if you interfere one more time I will kill you here this time. "
Hearing his name the one who was trying to save Shalba got shocked as I used my Space ability to close that space tear and said again
Issei :"You should go back and Warn Cao Cao to not interfere in my matters again. "
Issei :"And if he does I don't mind killing a few of the Hero Associations. "
After this I again used my Demonic sword as it cut apart Shalba's Head from his Body. Seeing all this as his space tear got closed and I killed Shalba, George was shocked but immediately retreated as he understood that he was not my opponent alone.
Ddraig :"you have really grown powerful. You only needed to boost yourself Two times in all this fight."
Issei :"Well I would not need it but I still wanted to end this early. And the Snakes he took were more than compared to what I knew. "
After this the Dimension of the game again got in control as I teleported outside. Although I could teleport even before but I already planned to kill all of them before. I also took Shalba and Diodora's Head with me to outside.
-----------------
After I appeared outside the battle here is already over. Girls and Others have already finished everything. Ophis also didn't do anything as she was with Rose. I also a bit shocked seeing all of the damage caused by the Devils. Sirzechs and Others are also present. When they saw me they all moved towards me And Started asking me
Griselda :"Are you okay, Issei? "
Xenovia :"Are you fine? "
Xenovia asked while having some concerned look in her eyes.
Issei :"Yes I am fine. "
Rias :"If you are fine, Then what about these injuries? "
She said while pointing a deep scar on my chest. Although I knew that Shalba will be nearly as powerful as The Real Maou Beelzebub after the powerup but I didn't expected him to also use those Different Elements Bursts this much and also the way he used those bees. So I just said
Issei :"I underestimated his powers a bit. "
Sona :" Let's Treat your injuries first. "
Asia :"Yes, Let me heal you. "
Asia said this while having moist eyes as she still blames herself for all this. After this She started using her Twilight Healing on my wounds. After my injuries got healed Sirzechs and Others got near me as he asked
Sirzechs :" So Issei can you tell us what happened inside? "
After this I explained everything to them and also showed them Shalba and Diodora's head as I took them out. They were still shocked that I fought that much devils by myself. And Also Defeated Shalba after he used Ophis' snakes. Then they asked
Falbium :"So you mean Diodora joined the Khaos Brigade and he was also behind all this."
Odin :"I didn't expected you devils to be this Careless. "
Sirzechs :"Sigh, I know we made a very big mistake. "
Odin :"Well you are really powerful, Issei. "
Rossweisse :"Yes, you are really strong. I am amazed you killed all those devils alone. "
Azazel :" Let him rest for now. we also have to settle many things after this mess. "
Saying this they all went to arrange everything as I went to Gremory House with all the Girls including Seekvaira, Misla and Kuisha as they were also worried for me.
