[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.

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.

MC takes Kiba's place at the exact moment he is reincarnated by Rias. In exchange, he has to get revenge on everyone involved with the Holy Sword Project. MC is prideful and has his own plans. He won't allow himself to be a servant. He will bide his time, waiting to get free and live his own life.

James Gallows es el nuevo Sekiryuutei y ha llevado una vida normal en la ciudad de New York junto con su madre, pero un día llega un hombre pelirrojo diciéndole que es su padre y que es el próximo líder del clan Gremory. Mira como James vivirá asombrosas aventuras cuando vaya a la ciudad de Kuo y conozca cierta pelirroja. OCx Harem. Futuro crossover con otras series

The usual...Issei discovered boosted gear at a younger age, he's OCC, and OP. Harem. Dragon faction.

Un futuro robado dos veces, un por un ser más allá de las estrellas y el otro por alguien a quien cree conocer. perdón por las faltas ortográficas

Ophis was in a state of… flux. She no longer regards her 'home' in the dimensional gap with the same awe she once did. Now she simply wanders the world, searching for some new meaning. What's that, a void in Kuoh? How… intriguing. Best hope this doesn't start anything too big…

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!

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

Una historia donde Issei conoce a Akeno cuando eran niños, sin embargo, un incidente ocurre provocando que estos dos se separen y generando el despertar del Dragón Celestial de la Dominación

[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

Boy meets girl. That's how people describe their story. From childhood to adulthood, Issei Hyoudou and Rias Gremory are best of friends together after their first meeting. There will be drama, comedic moments, and even more. But all these memories are precious, because they walk through all of them hand in hand. (A Issei X Rias fluff story, no harem)

The official REDUX of the original hit genderbent fanfic, by me, Misty! Still based on the anime, but open to suggestions concerning the light novels. Contains the same amount of manservice, pervertedness, & comedy as the original! Rated M for the obvious reasons. Constructive criticism is welcome! Credits to koneko-chan-hai on Deviantart for the cover picture!

In short, Riser doesn't get the chance to become that much of douchebag. Hopefully, the others get the chance to see that.

Yanderes I can't escape them even after being isekai’d

Issei didn't know what he was getting into when he made a deal with The Red Dragon Emperor, all he knew, was his friend was in danger and he needed to save her, no matter the cost. Eventually, Issei finds himself mixed up in the world of Angels, Devils and Fallen Angels, however, at least he has a way to fight for those he cares about. Less perverted, powerful, Dragon Issei. Harem.

I swear, I had no intention to follow the plot this closely... they came for me and dragged me into it! (Self-Insert)

Sígueme. Esa era una mala idea, una muy mala idea, pero si iba a saltar de un puente, seguir al demonio era lo menos estúpido que podía hacer.

Watch as the failure of the Gremory Clan rises through the ranks of the supernatural world even after he was abandoned. Follow Nicholas, son of Sirzechs Lucifer and Grayfia Gremory, as he moves forward and becomes the most powerful and influential Devil to ever exist and prove to the people who neglected and spat on him wrong, with some help of course. Neglected, OP OMC, Gamer Fic.

Issei x Harem. Series of Vanilla/Smut Lemon One-Shots & Spoilers. Latest: Raynare is released from the deepest dungeons of the Grigori—right into the clutches of the Sekiryuutei. He handles it poorly. Thankfully, Asia is there to save her. Now, the Fallen owes them doubly so and tries her best to make it up to them. (Deleted Irina's chapter)

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?"

Being the son of Poseidon and the Champion of Hades is stressful enough as it is. Thankfully, I had a busty blonde nine-tailed fox, her daughter and a silver-haired Valkyrie to help me deal with it. Now if I didn't have to be a teacher for a bunch of teenage girls, my life would be amazing. Oh well, at least the view is nice. Strong Demigod MC to OP Demigod MC, No Sacred Gear.

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

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!
