This is my first attempt at creating a study. The character's name is Halil Bozkurt, an original character (OC) of Turkish origin, who possesses the Boosted Gear. The story involves interactions between OCs and characters from Turkish mythology (OCxORC). You can find more information about Halil Bozkurt's character profile on the DxD Fanon Wiki.

This is just an anthology book of the boy Issei Hyoudou in multiple lewd situations with different waifus from different animes

Ise's friends turned their back on him, didn't they? They didn't consider his feelings and selfishly pushed their own agenda. These actions have consequences. They will learn. Even if they don't want to. The road to becoming an adult is difficult, isn't it? But for the sake of the future, they must all mature. No more being stuck. Make your move, Ise.

Issei is a beast. Not just any normal beast, but a Beast, and a perverted one at that. If that isn't bad enough, he also possess the ultimate weapon for sexual assault, tentacles! Good thing he has his wives Rias and Irina Hyoudou to keep him at bay. (FLUFFY DXD)

What if Issei was already a demon, what if he didn't have a Longinus but a mid-level Sacred Gear. A human was given the opportunity to become a demon,he accepted his life, it took a turn but after so long he and because of some things, he needs to move away.

Zorro Kuro lives most of his life as an ordinary kid helping his father with his restaurant. Imagine his surprise when he learns he has supernatural blood flowing through his veins and a destiny that threatens Japan as a whole!

Issei Hyoudou é um rapaz normal que vive com seus pais e frequenta o segundo ano do ensino médio, mas um dia foi surpreendido com uma mensagem de uma tela flutuante assim que acordou. O Sistema foi ativado, o usuário Hyoudou Issei agora é um Gamer de level 1 e deve evoluir ou irá morrer.

A shut in NEET dies without a single accomplishment he lived such a pitiful life even the gods took pity for that reason when his life came to an end instead of pearly gates a screen pops up

What if Issei's life was tweaked a little, changing not only him but the world around him. ( MAJOR REVISED)

After the defeat of Trihexa Issei finds himself in a familiar situation in the ORC clubroom. This time however not everyone turns against him but with his relationships far deeper than they were in the past what will the consequences be this time? [Issei x Small Harem] [Issei x Irina] (Betrayal, Riasbashing,Anti-ORC)

"What if Issei joined the Phenex family?" The story takes place during Issei's date with a strange girl named Yuma. Will Issei be slaughtered by the fallen? Will he be rescued instead? Perhaps a pair of high class devils are keeping an eye on the wayward teen? Other girls will include the majority of the Sitri and Phenex peerages. Yandere, Tsundere, Harem, Gender-Swapped Riser.

He used to be a casual fan, nothing special besides his home's circumstances. But after finding himself possessing the body of Diodora Astaroth, a minor villain destined to die a pointless death, suddenly everything started going wrong. With little more than his knowledge and eloquence, in order to survive and thrive... The new Diodora will take matters in his hands.

You know, I never expected to reincarnate, specially not in a blond vampire who can stop time and is also a crossdresser. Yeah, I could have gotten Dio, but instead I'm now Gasper Vladi. I wonder, what changes can I make to this world and get away with? They say the best way to deal with a sociopath is to not play their game, but what if I'm the only who can see all the pieces?

Remembering how I died was such a pain, but that's what I get for trying to chase a Tanuki. I was reborn, so that's great. What isn't is the fact that I'm in DXD without any way to defend myself. And an ability that I could do without. What's a man to do? Open a coffee shop! The supernatural doesn't attack people that fix them their morning coffee right? (Harem!, Human MC!)

Request fic for keller.blair1. Issei unlocked his [Sacred Gear], Divine Dividing on a young age and from a young age, he has been working for the Vatican as part-time exorcist. Fed up with the hypocrisy and decadence, he leaves Rome for a place he called home. Kuoh, which seemed to have become a hot spot for Super Natural Creatures. Perfect spot for a Dragon to build his harem.

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.

Sort of Sequel to 'Naughty Adventure' and 'Naughty Night'. Kunou wants to spend more time with her mom, she's 'friends' with an Incubus and has a plan. Hijinks of a dubious morality ensue because of course they do. Hardcore and not at all safe for family dinners. Stick to politics, you'll get less disgusted looks that way.

A boy died after a bike accident. However, his soul meets a being beyond gods who want him to have a second life in the World he chose while keeping the memory of his first life with a bonus of five wishes he can make.

Looking for a true love-story centered around Sona and Issei? This story has the following; Passion, deep romantic plot twists, internal and external character development and most of all, ecchi moments of comedy relief when things get too melodramatic. So, canonically, the story starts after the battle with Riser Phenix, then we converge from there on. -Romance, Tsundere, Fun-

This is the story of Ryun (Rune) Tsuchimikado, the pawn of Rias Gremory and The last of the Tsuchimikado family. Throughout Ryun whole life he has face hardships after Hardships, the lost of his family to the death of the person most dear to him.

What if Tiamat was also trapped in a sacred gear? well read as we follow the abused and cynical Ichigo as she and Tiamat Kick ass and chew bubblegum with no master to say what they can do. Maybe romance? I don't know yet

John Ajitani was simply an ordinary boy and an unexpected friend of the Perverted Trio, when one of the Beauties of the academy accepts his feelings he felt he was on top of the world, but a kidnapping forces him to snap back to reality and and try to answer a simple question ¿Who were those people that tried to kill him?
