I got reincarnated in the world of High School DxD. A dangerous world, sure. But, I also got to choose three Meta Essences as well as keep my past life's memories intact. Additionally, I'm a Devil now. A Pure-Blooded Noble Devil at that. With these cheats, let's see how will I flare in this harem-ecchi world. [SI/OC] [Essence CYOA] [Harem]

The Daughter of Lucifer and Lilith, opposite to god, Empress of Degeneration who wields evil.

Issei Hyoudo, resident pervert and member of the perverted trio of Kuoh Academy changed overnight. He was still a pervert but so much has changed. "Motohama, Matsuda, if you two try to mess with my work, I will beat the shit out of you and tie you up on the gates outside," Issei said, sternly looking at his friends while he used the sewing machine inside the club room

Thunder, a destructive, brilliant power. One who best represents this force of nature would be the Gods themselves. Thor, the Norse God of Thunder, prevented the fall of Asgard at the cost of his own life. Now, centuries have past and a new God of Thunder shall bring glory back to his name!

Shidou Koujiro's life turned upside down at his first and only Aespa concert. Now with the whole supernatural world wanting him dead or captured, he must find a way to save their family and the world from an ancient demon family working to break Lucifer free and bringing Armageddon

"One day, I opened my eyes, and found myself vomiting off the top of the mountain. Definitely not the best way to start my day, or evening at that point. Then I got attacked by a mutated snake, taken in by a perverted virgin kitty, and went back home to get blown up by a dragon. Twice. And that's only the start. At least it's exciting? This new life of mine." (Demigod SI-OC)

Rias doesn't know why she agreed to follow this old tradition of her family, but what Rias does know is that...following traditions was really fun. Adult themes, threesome.

Hyoudou Issei has always found his family shrouded in secrets, especially his enigmatic brother, who is not only in the same school and year as him but also constantly overshadows him with his looks and charm. Struggling under the weight of relentless comparisons, Issei retreats behind an emotionless facade... until he was suddenly face to face with a fallen angel.

A soul wandering the void is given a second chance at life and is thrown into a world he hardly knows. Fortunately for him, he is given a power that will grow over time as he, and others, explore its depths. How will the supernatural world react to someone literally playing games with them? Rated T for now, might upgrade to M later on.

All I wanted was to make enough money to live comfortably and put my little brother through college, but apparently, fate didn't like my plan, and kicked me in the butt so hard that I was sent flying until I ran into a bunch of supernatural problems. And that's not counting this diabolical screen that connects me with 5 other problematic people from other worlds.

Issei Hyoudou, dreams of making him and Seiji, his twin brother, "Harem Kings", sadly Issei is going to have a lot of trouble due to Seiji being a high-functioning autistic and an asexual, as well as many, many types of trouble ahead. Time to awaken the Beast.

¿Cuál es el verdadero potencial de alguien que ha poseído el poder del Dragón Emperador Rojo no solo una, sino dos veces? Ven y descubre que es lo que sucede cuando un portador del Boosted Gear renace nuevamente con este mismo poder.

Instead of Riser Phenex, Rias is engaged to someone else. Damian Mammon-Lucifer, heir to the Houses of Mammon and Lucifer. He is sent to Kuoh Academy to meet Rias, and a whole mess of problems follows with the likes of Fallen Angels, crazy Exorcists, and a massive terrorist group called the Khaos Brigade. Rated M for language, nudity and sex. It's DxD after all.

Betrayal... it's an action of betraying another. Damian Mammon felt that feeling in his heart the day he came home to find his girlfriend in bed with his best friend. Enraged and heartbroken, Damian left the Underworld, trying to rid himself of the heartbreak. By the time he returns, will he have changed and moved on? Rated M for nudity, sex and language.

An OC inserted as Rias decides to be a dragon, brought to you by my brain at four in the morning.

In one corner of the infinitely-vast universe, there lies an unfinished story of a first-year high school student burdened with the powers of the seven of the most evil creatures of yore. Now it is rewritten anew, as the shadows of both past and future begin waiting in this thorny road of self-actualization. (adopted from dvdryms' original story canceled in 24th of January, 2024)

The adage "be yourself" is the most common piece of advice passed down from hopeful male to hopeful male. Its legacy spans decades, maybe even centuries. How well do you think it'd stand against the forces within the walls of Kuoh Academy? You know, with all the hormones, devils and the lack of condom machines in the ladies' bathrooms? Yeah, the odds ain't great. OC-centric.

What if Issei actually found out the truth of why Rias saved him. From Raynare of all people. How is he going to grow stronger until he's able to free himself and protect everyone he cares about. Follow his path towards Domination. As he fights strong opponents and meets new friends along the way. (Less Perverted Issei) (No OP Issei) (Smart Issei) Issei/Harem OC, OC AU.

"Okay guys. Time to settle an argument. If you were to reincarnate in DxD, what race would you choose and why?" Some choose dragons. Some choose yokai. Others choose devils and another few, angels. In an era where gods exist and a myriad of races populate the planet, Igor made the most uncanny of choices. As for what it was, read on and find out. Available on RoyalRoad and Webnovel

When the next elder scrolls is written, you shall be its scribe. it was the fourth era 201, the Empire is waning and the Thalmor's power grows ever more. on this year, Dragons returned back to Nirn and Alduin the world eater sets out to devour the Cycle as it is his progress. An unlikely hero rises up To the challenge.

He was a relatively normal guy, he really was. So, why was it that after his death, unfortunate thing that it was, he woke up once more. And he did so in a similar but also very different world from his own and with a very strange Gamer System… But he had a second chance at life, so that was ok. What wasn't ok was that he had no idea what world he was in. That could be a problem.

A void was his home. He has been floating there in silence, staring off into nothingness. Everything was silent until he heard a voice. "How would you like to live out your fantasies and turn them into reality?"

High School DxD AU, what would happen if the hosts of Ddraig and Albion were directly related, and not only that, what if they were from the same family and are considered royalty That is what happens here, Issei Hyoudou, the host of Ddraig ,the Red Dragon Emperor, and Valerie Lucifer, the host of Albion ,the White Dragon Empress. See what happens here

On one hand, being reincarnated with an admittedly lackluster System is a dream come true. On the other hand, being thrown into the middle of a Civil War isn't exactly the best start to an Isekai adventure. (GamerSI-OC) (GamerxHarem)

The Bible God didn't plan ahead for a development such as this. The last fight between the previous hosts of both heavenly dragons had drastic effects on not only Ddraig but his current host as well. Now that he was free from his prison, nothing would ever be the same. This is just the beginning of a new story for Ddraig and Issei.
