This piece of fiction revolves around an ordinary human (OC) that ends up receiving the Boosted Gear, house of the Welsh Dragon Ddraig himself. His desires and values differ greatly from Issei Hyoudou, but is that all that's different about him? How will he distinguish himself among the long line of predecessors before him? To what position, does he aspire?

Issei debe acostumbrarse a esa vida oscura llena de dolor y tristeza

Tashiro Mari stalks Issei on his date and gets a nasty surprise when she wakes up the next day next to one naked as day Rias Gremory. Slight Rias and her peerage bashing (euphemism). Rated M for lemons in the future female OC.

What wasn't ok was that he had no idea what world he was in. That could be a problem.

Power fantasies oft reign supreme when you reincarnate into new worlds, especially ones you know. The world is rarely so kind, though. Even for those with powers that many would consider unique or even game-breaking, life can be ruthless. Being reincarnated with the wrong equipment was only the start, but what protagonist lets something like a bad hand keep them down?

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

Akeno le da una bienvenida bastante erótica a Issei en su primer año de la universidad. Historia perteneciente a Original Aramis

One was outcasted by the people around him and was experimented on. One was lied to their whole life, finding out a certain truth that shook her beliefs, they weren't treated with kindness and compassion but thanks to this that they found each other and now want nothing more than to watch the world burn and cause nothing but chaos.

Issei awakens the Red Dragon Emperor at a very early age, and Ddraig, seeing the opportunity to make his newest wielder one to remember, takes full advantage of the years that follow. The Issei that ends up at Kuoh Academy is nobody's fool. Warning: Mature themes abound!

What would happen if the Grey Sisters, of Greek legend told the leaders of the Greek Patheon about the dangers that were coming to the town of Kuoh? Threats that would, in time, come for them if not taken care of. Well, they would send a Demi-Olympian of their pantheon to help take care of said threats. Also, Issei has a twin sister in this story.

Life is never easy, sometimes it's painful. Issei learned this the hard way in life. Issei X Harem Fem Kiba

Nothing much, just me ranting about DxD fanon and all kind of stuff like lore, setting, misconceptions, etc...

Hyoudou Issei was your regular teenager. Everyone at school knew that. What they didn't know was that he was the heir of one Devil Pillar— neither did he though. With the power of Lust and friendship on his side, Issei now marches through the supernatural world, drawing blood from his enemies and making love to his harem as an Incubus. (Smut-fic with plot)

As part of one of Azazel's experiments, Issei was transported to a world other than his own. A world where the events that Issei himself had lived had taken a turn towards the worst possibility. In the short time that Issei will be able to explore this new world, he will meet faces, which while familiar, are very different from the people he once knew and loved.

God didn't plan ahead enough. 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 jail nothing would ever be the same. This is just the beginning of a new story for Ddraig and Issei.

After dying two otakus are given the chance to save the world of DxD, however, they are told this world is not the same as the one they knew about. This is an AU also known as Alternate Dimension Story.

[Issei x Tiamat/Penemue/Ross/Ophis] How much would a world change where the supernatural existed, and Angels behaved like Angels, Fallen Angels behaved like Fallen Angels, and Demons... behaved like Demons ? Issei has barely entered the world of the Factions, so he can't answer that question. But he will quickly find the answer.

Azazel, el gobernador de los Angeles Caídos, estaba aburrido, así que la mejor forma de acabar con eso fue manipular a Vali Lucifer para que le ganara un partido de ajedrez a Sona Sitri.

[Issei x Tiamat/Penemue/Ross/Ophis] ¿Qué tanto cambiaria un mundo en donde lo sobrenatural existiera, y los Angeles se comportaran como Angeles, los Angeles Caídos se comportaran como Angeles Caídos, y los Demonios se comportaran como...Demonios? Issei apenas ingreso en el mundo de las Facciones, por lo que no puede contestar a esa pregunta. Pero rápidamente encontrara la respuesta
