The grand event has finally opened High School DXD, the ultimate Harem anime. Hundreds of millions of users journey to this previously forbidden world to live lifetimes of adventures. Follow Red, a system user trying to stay away from the plot for the first time, only to be drawn in kicking and screaming. MA for lemons later.

An adrenaline junkie is reincarnated into a war-torn world with heavily nerfed Gamer System with practically no features. Born a slave, watch as he rises with nothing but will, grit and hard work. A Gamer with a not so conventional System. Harem, OC's out of necessity.

Dying to some punk with a gun via-sneak attack wasn't in his list of things to do that day but the Ex-Marine, Jack Haille is anything if adaptable. So when a disembodied voice promises him life again with a cool perk, he jumped at it. What's the worst that could happen, right?

After experimenting with tabletops and other games, Issei Hyoudou proceeded to set up a podcast to let others know about the odd joys of Dungeons and Dragons 5E. What he did not expect, was the piqued interest from the Supernatural. Rated T due to a lack of dark elements. Updates every other week or so. Spin-off story of 'Initiative is Rolled, My Dear'

I'm sorry. This world wasn't meant for Heroes little brother. Sometimes the people you read about in stories and legends are not what they seem, like you found out. Sometimes everything that happens is for a reason. I know what you might be feeling, I know you are angry with me right now, but I need you to understand you are going to become what you were always meant to be.

One-shot 'What if..'. Issei despertó sus poderes de una manera diferente, y para bien o para mal, eso trajo un cambio al mundo entero.

After a certain Event, Issei's hyodo entire destiny changed...one person was to be blamed for it, but who cares about that anyway...whats done is done, a certain Guy is laughing his ass of from how a little Event changed the entire timeline.

An American student of Kuoh Academy has a special power that rivals even the most powerful beings in the entire supernatural world. This is his story. (Strong, eventual OP OC) I DON'T OWN ANYTHING! JUST MY OC! (UNDER REVISION! CHAPTER 3 REVISED, CHAPTER 4 REVISION IN PROGRESS)

El aleteo de una mariposa podría causar un tornado en el otro lado del mundo, la historia sigue las misma leyes, un mechón de cabello fuera de lugar puede causar el surgimiento del guerrero más poderoso con los ideales de un mejor futuro.

When you find yourself in another world, it's easy to imagine just what you might do there, especially if it's one you know. Power fantasies oft reign supreme. However, sometimes the world isn't so kind, even to those gifted with unique abilities. Being reincarnated as the wrong gender usually doesn't help matters either! (Semi-realistic take. Looking for a cover!)

After her defeat at the hands of her brother, the Sapphire Dragon had her soul sealed within a Sacred Gear and was forced to sleep for 2,000 years. Now she has awakened to her first host, a shy young man who desires love. AU, OCxHarem, IsseiXHarem, slight crossover element to be revealed in a future chapter.

Not everything is the same. Issei grew up closer to the supernatural world than he ever knew. But when a tragic loss spurs him to try and gain power, everything will change. Watch as a very human Issei changes the mythological worlds in his own way (minor crossover elements) (Alt-Longinus Issei)

Long before he learns of the supernatural, Issei finds a certain wish-offering flyer. He begs to be able to meet a gorgeous big-breasted beauty. Akeno answers, seeing an opportunity to ruthlessly tease the infamous pervert. What follows... well, read on! WARNING: Mature Themes Abound!

So Reincarnation's a thing, right? That's good to know. what's more I've got a special cheat that makes me basically a D&D character... and just take a guess at who was a big D&D nerd in his past life! having my race changed to 'Devil' wasn't part of the plan, however. ironic. a devil with the powers of something that was said to be satanic in a past life. (SI-Oc) (Gamer System)

The bael clan holding the rank of great king reigning supreme as the highest house among the 72 pillars their influence great and resources plentiful lay claim to be the underworlds leading body. However with their influence slowly decreasing can the new heir to the throne reclaim its fading glory as the aristocrats fight back aginst the satans and gremorys rising influence.

Vincenzo 'Vin' Corsetti is your average high school student in Italy. Life is good. All he has to do is get some volunteer hours to graduate. He never should have volunteered at the Vatican. Now he's been drafted into an elite order of Exorcists in-training, facing insane beasts and monsters, and he's got a 'Sacred Gear' to figure out too. Hey, at least the girls are cute, right?

Tras pasar tantas adversidades, Ise y compañía aún deben hacer frente a retos más difíciles. La verdad de un pasado oculto, entes que desean acabar con el mundo. Mantener el legado de quienes salvaron el mundo antes que ellos. Poderes, sentimientos y dedicación, eso era lo que iba a cambiar el mundo. Cambio liderado por el Sekiryuutei Supremo, este es su Ascenso. (IsexHarem)

Issei's world is exactly as bland and boring as the one we all know and love. But the one he found himself in was far from normal. He awakes in a cruel but truly magical world where magic crystals jut from the earth, orbs of water float above the surface, thriving with life, dragons and wyverns roam the lands, some friendly and some not. Come all, The Isles of Paradise call

Follow Lily, a beautiful Succubus who is hated by her sisters for her amazing looks. With the threat of being exiled from the only Succubus city in the underworld, she is forced to collect a man's vitality in the dangerous Gremory territory. But being a virgin, she ultimately gets exiled. Luckily, her first job was with Issei Hyoudou. And thanks to him, she can finally live freely

Spiritual successor to the original HaiF! What do you get when you take a guy with a bit of a love for kicking established and seemingly untouchable bastions of power down a peg, an interdimensional deity, light crossover elements and drop it all into the 9th century? Well, who can say? Either way Pearson is going to make a killing off of all the textbook reprints...

Living a normal life was the idea for Issei Hyoudou, yet he did not know that he was one of the last dragon's hosts. Now every power will come to ask him if he wants to be their hero or become the one thing they never expect for him to become. The question about if Issei can go back to normal life or not is up to him. I don't own High School DXD!

By the the time I stopped laughing, by the time it wasn't funny anymore, it was already too late. ONE-SHOT

Someone from our world dies and gains the power of The Gamer and gets reincarnated into the Disney land of perverts (High School DXD) (SI,OC) Self insert.

Issei Hyoudou is dead... or that's what he thought before he next opens his eyes and sees he's been reunited with an old friend in possibly the most unexpected way. Join the next generation's Red Dragon Emperor as he navigates school, supernatural and suprise meetings with our favourite brunette and a slightly less grumpy dragon!
