A being more powerful than any before returns to grant Gods final wish. She creates an offspring that is meant to replace God. Issei Hyoudou. With infinite power, it will be up to Issei to choose to save the realm, or doom it. But he's still going to be the Harem King along the way. Absolutely OP!Issei, IsseixHarem, Male and Female Harem.

Ancient dragons in the past, beast that remained hidden from the eyes of even their own kind, making their will in the world through the hands of mortals with their powers.

(AU) Sometimes life gives you lemons, in this case, it gave him a dragon however he was already a demigod. How much worse could it already get? (Issei x Normal Harem) Maybe others?

Y ahí es cuando su problema número uno se convirtió en su problema número uno: a él le gustaba Hyoudo Issei

A Shin Megami Tensei X DXD Fanfic.

In a world where talented youths enroll at Lucifash Academy of the Arcane to first polish their skills so they can be noticed by their Rating Games senpais, a savant Issei got dragged into dealing with bullshit issues as fate tends to be a bitch. Like his mother. But hey, at the very least, he could chill out with his university buddies between issues. (AU DxD x Fate/GO)

Getting the [Boosted Gear] is expected for Issei. What if he gained it a month early and another one as well? Let the Games Begin... IsseiXHarem (if it wasn't, it wouldn't be DXD). Now has a TVTropes page!

In a fantasy setting, one would hope to throw around fireballs like it was nobody's business. Unfortunately, Magnus can't do that, but hey, that doesn't mean he can't do the next best thing. (SI-OC)

Basically an Issei revenge story continuing from "The Broken Revenant"

It's never easy to forge a new path. But, rarely was anything good easy. I'll carve out my own little slice of paradise for all of our sakes, even if every step through the briar makes my feet bleed. Warning: Discussion of Dark/Serious topics, Alternate personalities and backstories of characters, Heavily AU.

As possessor of the 14th Longinus and son of one of the four great Seraph Yamato had the potential to become one of the strongest within Heaven possibly even surpassing Michael.

OCxHarem, IsseixHarem, gender bends.

Being a half-breed in a society which values blood purity was not the most pleasant experience, but fortunately for Jack, he was never concerned about that due to being born out of it. Unfortunately, he'll have to dive straight in and deal with his Clan's declining reputation if he wishes to continue his terrorist hunt.

Issei's life went from bad to worse through the years. Abused by his parents, harassed by his peers and now wanted dead by the ORC due to his sister, and then killed by a Stray Devil left him broken, but after being revived with gifts that put the Longinus to shame, he'll make the world remember the forgotten, and that not always the main character is the hero.

Roxas Gremory, the son of Sirzechs Lucifer and Grayfia Lucifuge, a Devil who no Devil has seen hide nor hair of in two centuries, makes himself known to the Underworld again. But this time, he is different. Stronger, sexier, and... are those white Devil wings? Is he a Nephalem! Why yes, yes he is. Fem!Vali, Fem!Issei, X-Over Characters, Roxas/Harem. Lemons.

Being reincarnated into the world of DxD was certainly not what Nathan expected when he went out to eat at a restaurant. Being an Agares? Even less. Oh well, at least he has something to work with - before the clock runs out and the apocalypse awakens.

After watching the gruesome murder of his grandfather as a child, Akira Muramasa joins Kuoh Academy as a student, in hopes to have a normal life, while also hunting for the murderer of his Grandfather.

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… [Hiatus]

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)
