Ultimate Highschool DxD

I teleported away to the Underworld. I can see a huge castle in front of me. The engagement ceremony is being held here. The place is surrounded and filled with guards. I went towards the castle and the guards noticed me and charged at me. I used wind magic and blew all of them away. I broke through the front entrance of the castle.

Everyone was shocked to see me. A huge number of people are attending this engagement. I can see Riser and Rias. I can also see Sirzechs, Grayfia and Rias's parents.

Rias: What are you doing here, Ise?

Issei: I came here to save you. I won't let this engagement happen.

Riser: How did you come here!? Where're all the guards!?

Issei: I blew all of them away. I won't let you marry Rias, Riser.

Riser: You bastard!!!

Sirzechs: Calm down, Riser. I'm the one who called him here.

Riser: But why would you do that!???

Sirzechs: Why? Are you afraid of Issei? Don't tell me you're afraid of a human. Fight him and prove to me that you're worthy of my sister. Besides, it willl be great entertainment for the guests as well.

Riser: Alright, I'll fight him.

Sirzechs: What would you want if you win, Issei? Just ask and you shall receive it.

Issei: Then I want two things.

Sirzechs: What are they? Both of them will be fulfilled if you win.

Issei: First I want Rias Gremory and second, I want Riser's entire peerage.

Sirzechs: Ok, you'll get both of them.

Issei: Riser, fight me with your entire peerage.

Riser: Are you mocking me!?

Issei: I'm not weak. I am very strong. So, just do it.

Riser: Fine. This will be your last fight. You'll die like the weakling you are!

All of us got teleported to the arena. Riser and his peerage got ready. Four of Riser's pawns charged at me. They were Ile and Nel & Ni and Li. Ile and Nel readied their chainsaws and attacked me. I destroyed the chainsaws with my eyesight and punched both of them in the gut with slight force. They immediately retired. Ni and Li tried to use their punches and kicks to defeat me. I blocked their attacks and got behind them. I punched them in the back with slight force and they retired. Then Riser's other pawns Burent, Marion, Shuriya and Mira charged at me. Shuriya hit me with her staff putting in all her strength. I just stood there and let the staff hit me. Absolutely nothing happened to me, but her staff broke into pieces. I then punched her with slight force in the abdomen, causing her to retire. I then jumped up in the air and created three light spears. I threw them at Marion, Burnet and Mira. They retired for getting hit by those spears.

I got back to the and punched in the air with a little force. It generated a shockwave that blew both of Riser's rooks, Isabella and Xuelen away and they hit the wall creating huge craters on the wall and got retired. Riser's bishop Mihae formed a magic circle with both her hands gathering all of her demonic power and finally released it towards me. Ravel also created a magic circle with both of her hands and released all of her her flames towards me. Both of them combined their attacks into one creating a strong magical attack. I stood there and took their combined attack attack head on. I blocked their attack by raising my aura a bit and using it to protect me. Then I created a two small spheres of light and threw it towards the two of them. After being hit by it they got retired.

Then Riser's knights Siris and Karlamine ran towards me. Karlamine took her Flame Demonic Sword to attack me. I created a light sword and wielded it with one hand. I blocked her attack with it. Her sword was covered in flames. I then attacked her using slight force with my light sword. She tried to block it with her sword, but her Flame Demonic Sword got shattered into pieces. She then jumped backwards and took out her Fire Whirlwind Demonic Sword. It appears like a dagger. She used it to create a whirlwind of fire and released it towards me. I used my magic to create a whirlwind of water to counter her attack. It destroyed her attack and then hit her, causing her to retire. Then, Siris attacked me with her two handed sword named Zweihänder. I blocked it with my light sword and our swords clashed. I pushed her back with slight force using my sword. She backed off and swung her sword in the air creating shockwaves. Using my light sword, I cut through her shockwaves and threw my light sword towards her. The sword pierced her, forcing her to retire.

After that Riser's queen Yubelluna flew to the sky using her wings. By using both of her hands, she formed a big magic circle and released her magical attack towards me. Raising my aura a bit I deflected her own attack towards her. It hit her and highly damaged her. She then used a Pheonix Tear to heal herself. After getting completely healed, she readied her next attack. But before she could attack me, I used my lightning magic on her. She instantly got retired after getting hit by it. Now, only Riser left.

Riser had a look of frustration on his face. After all, I defeated his entire peerage just within three minutes and ten seconds. He was very angry right now. He revealed his flaming wings and flew to the sky. I used my wind magic to fly in the sky as well. He threw a huge fireball, which I took head on. Then we both started our air battle. I punched him the face and he hit the ground creating a huge crater. His injuries immediately started to heal. He flew towards me with full force covering his entire body with flames. I flew towards him with my covered in touki. We both clashed head on. He got damaged by my attack but again started to heal.

He then flew high up in the air and released his flames towards me. I used my own fire magic to counter his flames. I created a flame lance and light spear threw them towards him. He created a his blames. But my attacks still hit me.

He used his Hellfire attack and I also used my water magic against him. We both kept fighting for quite a while. His regeneration slowed down. Now, I was starting to feel bored. I punched him in in his c.h.e.s.t, breaking his ribs. He couldn't stand anymore. But he prepared one last attack infusing every last bit Pheonix flames left in him into that attack. He launched it towards me. I kicked his attack instantly destroying it. I threw a few light spears at him. All of them pierced his body. He was in a huge amount of pain. I then punched him in his gut. He spat blood and his entire body was covered with serious and deep injuries. All of his internal organs were ruptured. But I didn't rupture his vitals, to not kill him. I kicked him up in the air and punched in the air. It generated a strong shockwave that broke every single bone in his body. Riser fell to the ground with *BOOM* sound. He was completely unconscious. He is now walking on the bridge of life ad death. If I wanted I could've killed in the first strike. But I've no interest in killing him. After all, in the original timeline he later became friends with me. I was holding back a lot against him. After all, at full power my punches are the same as Sairaorg's if not stronger. I was announced the victor. I had a Pheonix tear with me. I used it to heal Riser. His body was completely healed but he was still unconscious. It's because his soul is on the verge of leaving his body and he is on the verge of death. But unlike my mothers and sisters, his soul wasn't damaged so I could still save him. I used the Holy Grail to save him. I then quickly hid it so that no one would notice it. Riser woke up and was surprised to know that I healed him.

Riser: Why did you heal me?

Issei: Because I've no interest in killing you. If I waited even for a second , you would've probably died.

Riser: Even of I died, it's not your problem. So, why did you save me?

Issei: Because you are not a bad person. You might be arrogant, but you're not evil. I know that you're good at heart. Besides, I don't want you to hate me. So, would you become my friend?

Riser: I don't know if you're stupid or kind. But I accept to be your friend.

We both then shook hands and teleported to the hallway. Everyone was surprised to see my incredible strength. I just smiled at everyone. All the girls and women started to blush because of it. Riser then removed his evil pieces from Ravel and the others. He told me that he would create another strong peerage and defeat me the next time we fight. I accepted hos challenge. Rias came to me as tears of happiness escaped her eyes.

Rias: You saved me, Ise.

Issei: I promised you that I would always protect you, so I'd to do it. Now let's return home.

All of us teleported back to the earth. Ravel and the others will be coming tomorrow as there're some formalities to be completed. I explained everything to Asia, Raynare, Mittlet and Kalawarner. They were happy that I could save Rias. We came to the school. Rias summonsed a Griffin. She was still blushing.

Issei: What's this for?

Rias: It's a gift from my older brother to you and me. Don't you want to ride it with me?

Rias looked very anxious. I replied with a smile.

Issei: I do. So, let's ride it and fly in the sky.

We both sat on the Griffin. Rias told the others to go back to their homes and they did. I and Rias sat on the Griffin and took off to the sky.

Issei: Wow! This is so much fun.

Rias: Ise, thank you for saving me.

Issei: No, it's no big deal at all. It's my duty after all, since you're my King.

Rias: Today you beat Riser. But it might not always be the case. I can promise that this isn't the last of our problems.

Issei: Then I'll give up my arms and my eyes if I have to.

Rias: Ise.....

Rias couldn't complete her sentence as I continued to speak.

Issei: I'll always save you. I'm your master after all. It's my job right...

I couldn't complete my sentence as Rias suddenly kissed my lips with hers. After a while, our lips separated.

Rias: How was it? T-That was my first kiss.

Issei: It was the best. But I want to say something to you.

Rias: What is it Ise?

I take her hands in my hands as I reveal my feelings.

Issei: Rias. Whenever I see you, my heart starts beating fast. After seeing you, I can't think of anything but you. Everything about you attracts me. Your beauty, grace, kindness, maturity, cuteness, elegance always attracts me. I love you, Rias. More than anything in this world, I love you. So, would you accept my love and marry me, my Ruin Princess?

Tears of happiness flowed out of Rias's eyes as she also kept blushing.

Rias: I'm so happy to hear that. I also love you, Ise. Since the day I saw you, I loved you. I will happily marry you, Ise.

She hugged and again kissed me. We continued our kiss for some time. Then we flew in the sky on the Griffin.
