Killing Kokabeil

As they all started fighting I saw a magic Circle appear near the battlefield. I teleported near to it as I know who can it be for. But i can't understand how they got to know about this attack. I think I have changed many things by being here.

From the magic Circle a Silver haired Maid Grafiya appeared. When she saw all of them fighting she started to rush over there only to be stopped by me as I said.

Issei :"Hello Grafiya, How are you here?"

Grafiya :"Can we talk later?I have to help them first"

Issei :"Don't worry about them They can handle all those three headed dogs as they are not as powerful as real one"

Grafiya :"They are your girlfriends, How can you be so relaxed, Even of the Fallen Angels leader is there"

Issei :"They are powerful enough for them and if anything is going to happen to them the first to face it will be me. "

Issei :"Let's say it's a good training for them."

After hearing me and seeing around her as all the girls were fighting very well. She calmed down and said

Grafiya :"Sirzechs-sama placed a magic detection device near this area so whenever there is high magic release he will know about it immediately."

Grafiya :"There were many people who wanted to take all serum from you as we cannot made it so many thought to kidnap you and others."

Grafiya :"That's why Sirzechs-sama did this so that we can keep everything undercontrol."

Issei :"So you mean there's a detection device here!"

I was shocked to hear this but it was true some devil may try to kidnap me or others to get the serum from me. But I also know that when they try to do it will be only their doom.So I just smiled towards Grafiya and said.

Issei :"So Grafiya, If you are already here let's have a something to eat until they finish all this. "

Grafiya :"Umm.... Are you sure this is Okay"

Issei :"Don't worry, Believe in me and the others. "

Hearing this she is still a bit heistant but she said

Grafiya :"Okay, But if anything is going to happen I will stop this immediately. "

Issei :"Okay"

After this I pulled two incredibly luxurious chairs and a table from my inventory which I bought from System. And placed it here. Seeing this Grafiya was shocked nt first but immediately regained her composure as it was rare for people to have space magic but not impossible.

As a gentleman I am, I got back a chair and pulled it backwards and gestured Grafiya to sit on it. Grafiya sat on it gracefully when she say on it she looked like a queen sitting on her throne except for the Maid clothes she was wearing. Then I also sat on the chair in front of her and said

Issei :"So Grafiya what would you like to eat? "

Grafiya :"Anything that you have right now. "

After she said this I buyed some freshly prepared food from the system. It even sells this type of things. I got to know about this when I was on a getting bored and checking the shops for available this. These things shown up I "Extras".Their price increases with quality. For Grafiya I chose the best quality I can decide at this moment would suit.

After she saw all those food I thought came to her mind that if I had already planned all this but she neglected it as no one except Sirzechs knew about her arrival. Then as we started having our little dinner. The girls are still fighting against them

Irina and Tsubaki have very much taken care of their opponent. Irina is using space sword with the sword techniques she learnt from Griselda with Tsubaki using her magic. Reya, Tomoe, Raynare and Momo has also nearly defeated it. Akeno has already half-killed her opponents. Tsubasa and Koneko are also have fighting well. Gasper was also helping by using his Darkness manipulation and Forbidden Balor View. Asia was using her Twilight healing to help the others.

Rias and Sona are fighting with Kokabiel using their Destruction magic and Water magic. While They were fighting Kokabiel suddenly shouted as one ball of destruction hits his chest.

Kokabiel :" Aarararrggggg.... "

Kokabiel :"I WILL KILL YOU ALL. "

Saying this he started creating Two huge Spears using his light magic. Rias and Sona Also used their strongest magic to counter it. When Kokabiel throws his Light spears towards them, Rias used her Power of destruction to create many spears and started throwing it towards him, Sona used her water magic to create many water swords and controlled them to cut the giant light spear from different parts.

When they clashed in mid-air the Light Spear started breaking all their magics and moving towards them slowly but it also has its energy decreased from before. When the spear was just about to reach them suddenly a Kuroka came in front of them and said

Kuroka :"You did well now leave the rest to me here and help others"

Saying this she used her mgic to create a defensive barrier around them. When the Spear touched it A Sudden BOOM!! was heard and everything around them turned into mist after the most cleared all three of them were okay. After this Kuroka used her [Touki] and went forward to fight With Kokabiel. Rias and Sona also went to help others

After fighting for some rounds Kuroka said

Kuroka :"You shouldn't have come here. "

Kokabiel :"You can't do anything to me"

Kuroka :"Let's see"

Saying this she used [Kasha] to summon multiple firewheels to attack him. After this she used one the skills I taught her using wind magic [Wind Cutter] which cut off two of his wings. He screamed in pain after one of his pairs of wings got detached. Then their battle continued. After sometimes when Kuroka was just going to finish him. I stopped her

Issei :"Kuroka stop"

Then I turned to Kokabiel and said

Issei :"Kokabiel, Let me ask you do you want to know who was the one who killed Freed and took Three fragments of Excalibur from him? "

Hearing this he was shocked. He had no interest in knowing the one who killed freed but he still wanted to know who have those fragments and when I said this he immediately understood who killed Freed and took those fragments. So he asked

Kokabiel :"You are the one who have those fragments!!"

Issei :"I think after all you are not a fool. Yes I was the one"

After hearing this he immediately attacked me trying to get those fragments. But to his disappointment I disappeared from there and stood away from there and said

Issei :"Don't try to attack me you can't harm me. "

Issei :" First you should look around you"

When I said this he looked around him but what he saw greatly shocked him. All the Cereberus he summoned were all defeated although they were not the bigger ones but they were still powerful. And now all the others were surrounding him where he was standing. Suddenly he laughed and said

Kokabiel :" Hahahaha..... You all are really strong. I didn't think you could be able to beat them. "

Kokabiel :"But you will all die today "

Saying this he was going to use another summoning magic to summon bigger Cereberus So he could barely dodge it. He could Summon them before but he didn't think it was necessary but now he could only use this but then he heard my voice.

Issei :"You will not have the chance to do so"

I used my demonic sword to slash through his neck he was already in a bad condition due to his fight with Kuroka. So he was barely able to dodge it but just as he dodged Rias and Other used their magic to direct a one-hit to him. Due to the combination of all of their magic powers he could not survive it and died there without leaving a corpse.

When he died Grafiya appeared before them and said

Grafiya :"I am very shocked to see how strong you all have become"

Rias :"Big Sis, Why are yo here? "

Grafiya :"When I knew that you were all attacked I immediately came here but Issei stopped me from helping and said it will be a good training for all of you"

Grafiya :"But Now I know that you all didn't needed my help."

Rias :"No Big sis, We would have needed your help if Kuroka wasn't here. "

Issei :"Okay now let's go back to our house. Grafiya, I want you to also come with us."

Grafiya :"Okay, But I will not be there for much time"

After this we all were just going to walk to house house but then we felt a strong presence there. and When we looked we saw a young man standing in the air.
