Reincarnated In High School DxD

There is no second vow and demons become devils. (A correction.)

After these events, Grayfia and Madara came closer. Madara continued to train hard and he gained strength quickly.

After a year, Madara was in the chalet lounge in the forest with Grayfia in her arms. Madara was brushing Grayfia's hair.

"Honey, I have to leave now."

Grayfia, who was relaxed in the arms of her beloved, froze.

Grayfia turned around and asked him. "Why?"

Madara smiled and told her that he had to kill some creatures.

"Okay, but I'm coming with you."

"It's too dangerous, you risk dying."

"I am coming with you."

Looking at Grayfia's eyes, he sighed and he agreed.

Madara got up with Grayfia in her arms and kissed him. After a long kiss, Madara looked at Grayfia and said, "I will protect you, but if I tell you to run, you run."

Grayfia looked away but Madara forced her to accept.

After that, Madara left the cottage with Grayfia. Madara turned to see the wooden cottage and Madara made different signs of hands and the cottage disappeared into different particles.

Grayfia seeing the cottage in which she had spent the best moments of her life dissolving felt sad but she did not stop Madara.

After the disappearance of the cottage, Madara and Grayfia left the forest and Madara began to chase the creatures from the chaos, the old ones.

Three years later...

Madara and Grayfia had traveled all hell under the jurisdiction of the devils and Madara massacred all the ancients in his path. Madara's training had brought him to the top, he was as strong as Madara in his clash with Hashirama. Currently, he could use the wise mode thanks to the cells of Hashirama and the chakra of Juubi.

Grayfia was amazed by the creatures Madara faced. As a devil who had seen innumerable foul things she recovered quickly and asked Madara what these creatures were. Madara replied that they were creatures that had to be destroyed on sight.

_________________________________________________________

Currently, Madara and Grayfia were at the top of a cliff. In recent months, both had found devils of the Old Satan Faction faction that were merging with parts of the old ones. Madara found this sight repulsive and Grayfia frowned.

"Who can change the devils and merge them with these creatures?"

The two investigated and finally, they arrived at the source of these bodily changes.

At the bottom of the cliff, was the source of these abominations. Madara took Grayfia's hand and jumped. Madara used levitation and Grayfia spread her wings.

When they arrived at the bottom of the abyss, in front of them was a huge mansion. Madara unfolded his Sharingan to find vital signatures but he found nothing, while he was going to turn off his Sharingan, he saw that the manor hid an underground area with a great concentration of life.

"There is a huge crowd down there, Grayfia, be careful."

"Okay."

Madara and Grayfia made their way to the empty mansion, and Madara and Grayfia made their way to the hidden door to the underground area.

As the two followed the dark hallway, someone watched them with a smile on their lips. Madara suddenly turned around and threw a kunai in the direction from which the gaze was coming. The kunai killed an eye that was glued to the ceiling.

Grayfia saw Madara kill an eye with his kunai, and she told him that this eye is a familiar recognition. This allows you to see pictures from another place.

"A camera ... we are discovered then." Madara thought.

Madara nodded and continued to follow the path, Grayfia followed him.

Eventually, the two led to a medical room with beds on which were corpses of devils with tentacles coming out of the eyes, ears or other openings.

Both kept their faces impassive and both continued on their way. As the two moved forward, a putrid odor was felt. Madara warned Grayfia. Madara's eyes sharpened and his concentration was at its apex.

After minutes of walking, they found themselves in a huge room with devils lying on beds. These people had pipes on their bellies that came from the ceiling.

These pipes transfused something to the body of the devils lying on the beds.

Madara activated his Sharingan and noticed that the devils were still alive. As the two inspected the room, applause was heard.

"* Clap * * Clap * * Clap * My dear sister, what are you doing here?"

Madara and Grayfia looked at the source of the voice and Grayfia's body trembled when she saw who it was.

"Br-Brother, what are you doing here?"

"Hahaha, what do you think I'm doing, I'm trying to change devils and make them more powerful to dominate this world!"

Grayfia was silenced because she knew her brother's ambitions, but she did not know he would reach that point.

Madara who was watching this scene spoke.

"You know at least what you do, you play with fire, these creatures only seek destruction, they manipulate you."

"Hahaha, manipulate me, I'm Rivezim Lucifuge, nobody manipulates me!"

Madara shook her head and thought that arrogance always causes decay.

"We will not have to talk then, you will not listen to us ..."

"He, I'm looking for power and nothing will stop me, not even my family, you will not leave this place."

Madara looked at Grayfia who was stunned by the revelation that her brother was a monster. Madara sighed and prepared for the fight against Rivezim.

Rivezim raised his hand and a gray energy was thrown towards Madara that he dodged with Shunsin no Jutsu. Madara looked at this energy carefully as he could feel a chaotic energy inside.

"You are a real madman!"

Madara made different signs of the hand and shouted "Fūton Atsugai!" A powerful gust of devastating wind was blowing through the mouth of Madara who rushed to Rivezim.

Rivezim jumped on one side to dodge because he felt that this attack could be dangerous to him. Rivezim then looked at Madara and he put both his hands in front of him to create a gray ball which he launched towards Madara. "Devastating Orb!"

Madara felt the power contained in this ball and behind him was Grayfia, so he raised his right hand and summoned a bijuudama with the juubi chakra.

The two orbs met and the Bijuudama took the lead and headed for Rivezim. Rivezim felt that Bijuudama could reduce it to dust so he unfurled devil wings and flew.

Bijuudama touched the ground after Rivezim's flight and a titanic explosion occurred. The abyss shook and the mansion began to crumble.

Rivezim, who was in the sky, watched the mansion go by after leaving the cellar and clenched his teeth as he saw his work of creating perfect devils being destroyed before his eyes. He then looked for Madara but did not find him.

After launching the bijuudama, Madara went to Grayfia who watched the fight and took her in his arms and transferred her to her space world with her Mangekyou Sharingan. Madara then hid herself to take Rivezim furtively.

Rivezim kept looking for Madara because he still felt like he was in danger. At a certain moment, behind Rivezim, one could see two demonic red eyes staring at him.

Madara was hidden in the shadow of the cliff and the smoke of the collapse of the mansion. While Rivezim was back to him, he took the opportunity to jump on him and cut an arm with his Gunbai. Rivezim tried to dodge but he lost his left arm on the way.

"Gyaaaaaa! My aaaaaarm!"

Madara waved her Gunbai to get rid of the blood and stared at Rivezim with a smirk. Rivezim seeing this smile became furious and his eyes became red with anger.

"I'm going to kill you! Kill you!"

"So come dance with me."

Rivezim roared and a gray aura escaped his body. Rivezim's body began to swell him into a bodybuilder, his magic energy tripled and his eyes became red blood.

"Now you are going to die painfully, human!"

"Come and try."

"Aaaaaaaah"

Rivezim roared and rushed to Madara. Madara seeing Rivezim rush smiles and Rivezim throws a punch towards Madara. Madara para with his Gunbai and shouted "Uchiha Gaeshi!"

Gunbai shone and Rivezim's fist was returned. Rivezim flew away, spitting a sip of blood. Madara watched Rivezim get up with a smirk.

"So, always leaving."

"Aaaaaa, I'll kill you!"

Rivezim flew into the sky and raised his hands in the air and shouted: "It's the end for you!" Madara with her Sharingan saw a huge amount of mana creating a ball over Rivezim's hand.

"You are really crazy."

The ball that Rivezim creates, used the energy of the old, a destructive energy and he infused a huge amount of mana as fuel.

This immense energy attracted the attention of several powers of hell that rushed towards him.

Rivezim looked at Madara and with a mad look he shouted "Dieeeee!"

Madara looked at the ball with a raised eyebrow and tidied her Gunbai. Madara made many signs of hands and he ended up laying them on the ground shouting "Kuchiyose no Jutsu- Rashomon!"

With Madara's cry, five titanic doors came out of the floor with demonic faces painted on the doors.

The destructive energy ball that Rivezim launched, was stopped by the first door five minutes before destroying it, the second was also destroyed after forty-five minutes but the ball was stopped at the third door.

In the distance, the devils and other creatures who felt these powerful energies saw a huge ball that could have killed them being stopped by daunting titanic gates. All narrowed their eyes.

Rivezim watched Madara desperately after the doors disappeared.

"You are weak, but I will give you a dignified death in your sister's name."

Madara waved her hand and eventually spit a ball of fire at the sky.

Rivezim looking at Madara's actions was perplexed but he pulled himself together and started attacking Madara with everything he had to survive. Madara dodged all his blows but he was sometimes hit in his armor.

As time went on, Rivezim felt more and more worried as he watched the smile on Madara's face. He felt himself caught in the palm of a being with whom he should not play.

Madara during his body-to-body fight with Rivezim raised his head to look at the sky and said, "It's time."

Rivezim felt a shiver in his spine.

Madara distanced herself from Rivezim and flew into the sky with the help of Juubi and memories of Madara from NarutoVerse.

Madara looked at the storm in the sky created by the heat of the fireball and saw the lightning crossing the dark clouds of the c.u.mulonimbus. He smiles knowing that he can use a mythical technique.

Madara raised his hand to the sky as she was surrounded by lightning and looked at Rivezim.

"If you survive, you will still have a chance to live ... Weak."

Rivezim watched the storm in the sky strengthen and head towards Madara. A bad presentiment overwhelmed him and he deployed the rest of his energy to create a powerful shield.

The lightning surrounded Madara and Rivezim saw a scene that will haunt him forever. A majestic dragon descended a sky and surrounded Madara. Madara lowered her hand to Rivezim with a single word impassively said.

"Qirin."

The dragon roared and rushed to Rivezim. Rivezim felt the fear for the first time in his life and he poured all the energy he had into the curl around him.

The dragon hit the shield the first time and cracks filled the shield, Rivezim panicked and injected even more energy. The dragon rushed a second time and the shield was destroyed. Rivezim watched as the lightning dragon opened his mouth with the intention of killing him.

Rivezim desperately covered himself with his wings and the dragon finally bit Rivezim. At the same moment, a heartrending cry was heard.

Madara looked at the scene with a cold face but he felt powerful energies moving towards his position. Madara turned to see a hundred people flying towards the combat zone.

Madara recognized some of them. He recognized Sirzechs, Zeoticus, Ajuka, Serafall, Lord Sitri, Falbium, Lord Phenex, Tannin, Azazel, Lord Bael, and other superpowers.

Everyone looked at Madara floating in the sky. All fixed this man in his mid-twenties who possessed a crazy charisma. A height of 1.80 cm and long raven black hair and demonic red eyes with three tomoe. Red samurai armor with only a few scratches.

While they were silent, Sirzechs stepped forward and asked: "Hello Sir, can I know who you are?"

Madara was silent and finally, he replied "... a traveler."

"A traveler? ..." Everyone frowned as they thought Madara was making fun of them.

Sirzechs maintained his calm and with a smile, he asked: "We would like to know your name?"

Madara looked at them all with her Sharingan and everyone was uncomfortable under her eyes. He felt n.a.k.e.d under his eyes. Finally, he looked Sirzechs in the eyes and with a smile in the corner of his lips he answered "Madara, Uchiha Madara."

"Madara ..." Everyone memorized this name because they all had a bad feeling.

Sirzechs asked what had happened here because now hell was in a civil war. There was the Old Satan Faction, The Fallen Angels and the New Devils Factions.

Madara did not answer and headed towards the place where Rivezim was struck by the lightning dragon.

Some devils were angry seeing Madara ignore the Lucifer, but Azazel had a smile on his lips. Sirzechs was indifferent to him, but he felt irritated because since his rise he was still under the spotlight, but he knows that not everyone likes him.

While Madara still felt vital energy in the rubble of the cliff, Lord Phenix and Lord Bael got in his way.

"Who do you think you are, kneel down for me!"

"You are only a human and you are arrogant, you are looking for death."

Madara looked at the two in front of him with an impassive face and he turned to look at Sirzechs. Sirzechs raised his hands in the air to show that he could do nothing.

Madara thought, "Boring."

Madara looked at both of them and he changed his Sharingan to Mangekyou Sharingan. Lord Phenix and Lord Bael saw the change in his eyes and they had a bad feeling. The others saw both change their expression but they could only see the back of Madara so they do not know the reason.

Madara then looked at the eyes of Lord Bael and Lord Phenix and used Tsukuyomi.
