Ultimate Highschool DxD

When Grayfia opened the door, she greeted all of us. Then she lead us inside inside. A man and woman greeted us inside the Gremory palace. The man had crimson hair and blue eyes. He looked like a handsome middle-aged man. He was Rias and Sirzechs's father Zeoticus Gremory. The woman looked like she was in her early twenties. Her face was incredibly charming, while her s.e.xy body was a delicacy every man d.e.s.i.r.es. She had light brown hair with violet eyes. She was Sirzechs and Rias's mother Venelena Gremory.

"Hello everyone, I'm Rias and Sirzechs's father, Zeoticus. This is my wife Venelena. All of you must be Rias's peerage members."

"Please take care of us."

All of us said in unison. Venelena then looked at me. She kept staring at me for some time. Clearly she was mesmerized from my looks.

"You must be Rias's boyfriend."

"Yes, my name is Issei Hyoudou. It's nice to meet you both."

After concluding the introductions, all of us went inside to have lunch. After the lunch everyone gathered in the garden of the palace. Rias called all of us to discuss about our training regiment. She assigned several training methods for all of us. Everyone was just about to leave, but I stopped them in due time.

"Everyone I've something to say."

"What happened Ise?" asks Rias.

"Rias, your training methods aren't bad. But I've better ideas. If you don't mind, I can train all of you."

"Please explain."

"It's hard to explain. But this summer vacation I'll train of you personally. All of you already know how strong I am. I promise that the results will be more than satisfactory."

"We believe you Ise. Since you say so, we'll train with you."

"Alright. I'll start all of your training from tomorrow. It will be pretty harsh, so be prepared. Now go and o whatever you want. Tomorrow come here after breakfast. I've some work to do, so I'll be going now."

Saying that, I teleported away from the Gremory palace.

.....

After the I left the Gremory palace, I appeared in front of a huge cave. The cave's entrance was huge and gave the impression that something large resided in it. Ddraig called out to me.

[Partner just activate the Boosted Gear. She will immediately come out.]

Hearing Ddraig's advice, I activated the Boosted Gear. The cave began to shake violently. The earth was shaking as the sound of large footsteps echoed in the vicinity. A pale blue western dragon with celestial blue scales came out of the cave. It was the strongest Dragon King. The Chaos Karma Dragon, Tiamat.

"I see you are another one of Ddraig's wielders."

"Yes, I am. I am the Red Dragon Emperor Issei Hyoudou."

"Since Ddraig destroyed my lost treasure you have to retrieve it. Otherwise I'll burn you to death."

"I came here for that reason."

Saying so, out of the air appeared various items. These were the treasures Ddraig borrowed from her to fight against Albion. They were destroyed and got scattered amidst there battle. I managed to find all of them. Tiamat got very happy at the sight of those treasures and quickly took them back. It seems they were of great importance to her.

"Thank you for this."

"You're welcome. But I want something in return."

"What would that be?"

"For you to become my woman."

Hearing my words, she was shocked. No one in her entire life dared to ask her that.

"You need to defeat me in a battle. Female dragons only choose men who're stronger than them. But bear in mind it'll be a fight to the death."

"I'm confident in my victory. Let's battle."

My lips curved upwards in a smirk. Tiamat got ready and immediately attacked me. I dodged her attack by rolling sideways. I took to the air and activated my Balance Breaker.

[WELSH DRAGON!!! BALANCE BREAKER!!]

My entire body was covered with scail mail armor. Two dragon wings appeared behind my back and I charged at her with speed and power. I released a punch which was blocked by her arm. The battle had just began!

I got back and she breathed her dragon flames at me. I blocked her attack with my Dragon Barrier. A barrier created from the huge Dragon Aura created by the Boosted Gear. She readied another fire breath. But it was ten times stronger than the last one. I attacked her with a large Dragon Shot. Both attacks cancelled each other out.

She unveiled her wings and flew up to the sky. We both began our air battle. I released several punches towards her with my fists covered in Dragon Aura. She countered them with her own punches. She really was a menacing opponent. When your fists won't work, it's better to use magic. Several white magic circles appeared throughout the sky. All of released several attacks. With the elements of flame, ice,, thunder, wind and light, the attack wasn't something to be taken lightly.

"Full Elemental Discharge!!"

As soon as the attacks were about to hit her, Tiamat activated her own Dragon Barrier made with her powerful Dragon Aura. The barrier had twenty layers. Thirteen layers broke upon the impact of my attack. She understood that I was no joke.

She then charged towards me with high speed and punched me hard. Her punches have become even stronger! The punch upon impact sent me towards the ground. I avoided a collision and flew back up. She swing her large tail at me, with strong Dragon Aura. I hastily boosted my strength.

[BOOST BOOST BOOST BOOST BOOST!!!!!]

I activated my Dragon barrier with managed to withstand her attack. But it was on the verge of collapsing. I sing my own tail and hit her back. The impact caused a part of her scales to break. She charged pale blue flames in her mouth. She was charging the attack with her Dragon aura.

A magic circle appeared on my right hand, while a red sphere appeared in front of my left hand which was curled into a fist. [BOOST BOOST BOOST BOOST BOOST BOOST!!!!] I charged both of my attacks. Then I released them. From my right hand, I released the Hydro Blast and from the left hand I released my strongest Dragon shot. Both attacks fused together to become stronger and headed towards her. I shouted the name of the attack "Hell Blast!!"

She also released her flames. Both attacks intercepted one another. After some time, my attack overpowered her attack and destroyed it while heafing towards her. She activated the barrier. The barrier was now empowered with all of her Dragon Aura. But the barrier broke and the attack hit her. Smoke covered the area. After the smoke cleared, Tiamat had several bruises and injuries on her body.

It was clear who was stronger. But she looked at her right, she saw a hole in her right wing. She was shocked. Dangerous blue aura rose from er body, flooding the vicinity. Her aura changed Ron pale blue to dark blue. It was clear as day that he was fuming with rage. Only two words appeared in my mind (Oh shit.)

Tiamat's eyes went bloodshot. She looked at me with rage. She disappeared from her position and appeared right in front of me. She became even faster!! It must be Dragon's rage. When dragon's get angry, they become several times stronger. I needed to end the battle quickly. Her strength rose several times. If I did not defeat her now, the dragons in the area will definitely die from her wrath.

She threw a strong punch at me. I quickly evaded the attack by getting away from her. I activated the Triaina. I shouted.

"Welsh Sonic Boost!"

"Armor Release!

[CHANGE STAR SONIC!]

My speed increased and most of armor was she'd keeping the absolute minimum for flight increasing my speed even further. The armor then morphs into a more aerodynamic form. I flew back to her with my godspeed and crashed into her c.h.e.s.t. The impact sent her back and made her spurt blood. She attacked me with her tail, which I evaded with my speed. I again shouted.

"Welsh Dragonic!"

[CHANGE SOLID IMPACT!]

I have at Tiamat and hit her with it's Solid Impact. She releases a punch with all of her strength. But my punch broke her arm and with the other hand I hit her back with Solid Impact. The injury was serious with a lot of blood.

The attacks pushed her back several metres. I dispelled the bulky armor and shouted.

"Welsh Blaster!"

[CHANGE FANG BLAST!]

Two cannons appeared in my back. They started gathering energy and power. A large red sphere appeared in front of both the cannons.

"Dragon Blaster!"

[Dragon Blaster!]

I released a large red bean that made it's way to Tiamat. She readied dark blue flames in her mouth. She released the attack filled with all her might. Both attacks intercepted creating a large and deafning impact.

BOOOM!!!

My blast overpowered hers and ended up hitting her. She went unconscious from all the damage. Her body was covered with lacerations and avulsions with her scales shattered and her body all bloody and severely injured. I dispelled my Balance Breaker as well as the Boosted Gear. I got down on the round and approached her.

I used Sephiroth Graal to heal all of her wounds. She slowly opened her eyes and got up. Now that I look at her, her human form is absolutely enchanting. Long pale blue hair and aqua eyes. She could snatch any man's heart with a glance. Her tall hourglass figurewith huge curved in the right places, could excite anyone. Her beautiful face and those soft pink lips made me want to kiss them at once and never separate.

But I quickly broke out of my daze as Tiamat got on her feet.

"Wow! You're very strong! Even managing to defeat me when I was enraged. I'll definitely become your mate."

"I'm happy that you accepted my offer."

"I want to ask you something. You don't need to answer it if you don't want to, I'll go with you regardless."

"What is it?"

"Why do you want me to become your mate?"

"It's because I'm in love with you." I said with a smile. At my words, she couldn't stop herself from blushing.

"O-Oh I s-see." She stuttered. Then I took her with me to my pocket dimension. I introduced her to everyone inside and she befriended them. I told her to keep the fact that I've the Boosted Gear a secret. Leaving Tiamat to have fun with her new friends, I exited the pocket dimension. I then teleported back to the Gremory Palace, directly to my room. I turned the lights off and went to sleep. Tomorrow I'll have to train everyone.
