A story that mostly focuses on Original Characters. Rated M for safety.

Once, Belzerg was a world of magic, laughter, and hope. But the magic died for corporate greed, the laughter was sold for one more chit, and hope was buried under layers of corruption.

Short story compilation with ties to the fifth volume of my fic; as such, there may be spoilers. It's recommended—but not strictly necessary—to read the mainline fic before reading the stories in this compilation.

Instead playing JRPGs, Aqua watched too much mecha anime growing up. Now, the Galactic Federation needs a hero to save them from the Space Devil King (who definitely isn't space Nippo-Hitler with four forms), one is superb at piloting a mecha, as well as brave and true. Instead, they got Kazuma. And to think Aqua and Eris are using their vacation days for this.

I got drunk and decided to write some stuff. Disclaimer: this is shit. I apologize in advance.

Av'Rick Mephilis isn't what many would call normal. How will the people of a fantasy world react to a guy who's weirder than those of the Axis Cult or the Crimson Demon Clan. Rated M because of Darkness.

Killed once again, Kazuma expects a one way ticket back to the afterlife. Instead, he finds himself cursed with the power of the most powerful vampire to ever live. Expecting to finally live out his edgy fantasies, Kazuma and the gang become embroiled in a conflict with a mysterious threat who's strength and cruelty defy logic in this comedic tale of a cruel world. (HEAVY AU)

With the Power of GET CREATIVE supporting him, Kazuma is ready to start his journey in the new world. Oh and Aqua's going also but not because she wants to. Minor Crossover with Hidden Dungeon Aqua Bashing Megumin bashing Eventual harem Eventual Lemons Konosuba hijinks

Perfection. All in one word. Kazuma witnessed her with his eyes. It was a single encounter. But that's all he needs. To know what he would struggle for no matter the adversaries he had to face in this different plane. And with this... relationship-based system? Yeah, something like that, maybe, just maybe, he could stand side by side with such perfection. Not just as a believer.

Kazuma worms his way into Yunyun's life and Yunyun learns how fun games are when there's someone else there with her.

The fifth volume of the series.

A series of 'what-if' one shots; primarily based on scenes from the anime and light novel. Reader suggestions and recommendations are welcomed. Please see the AN of chapter one for more details.

During their visit to the Arcanletia hotsprings, Kazuma ends up taking Chomusuke for a bath, and has a fateful confrontation with a certain overly endowed elfish woman. What follows will forever brand him as the worst of perverts, and send the world down the path to a Mexican Standoff, Explosion style.

Arc 9: A Hero for This (Alternate) Princess

Kazuma and Aqua are tossed in a much more brutal, unforgiving world where there is no resurrection or second chances. This place is much less like a game, the character's personalities are more grounded, and our hero meets and brings the original party together in a very different, but much more intimate way, with a lot of blood and tears in between. (contains smut)

Kazuma entered into the fantasy world, hoping his desires to be made top priority. This time, he notices something before Aqua's bitchy attitude distracted him. Porn with Plot, just so you guys know.

A lonely teenage boy travels overseas to Japan where he dies. He gets sent to another world with the chance of a new start. Unfortunately, he's forgotten even in this world until he meets another particular lonely girl. Will these two loners grow closer together as they discover a more significant threat than the demon king himself?

This is not how I wanted my fantasy adventure life to be, and nothing goes as I planned. But when your life is this Chaotic! Every little happiness becomes a blessing to you.

Kazuma begins to have feelings for Darkness during the week Megumin is away… Is it just sex or more than that? After slowly learning more and more about Darkness, Kazuma learns some ugly truths about her and her masochistic side. KazumaXDarkness - AU where he’s in love with Darkness after breaking up with Megumin :)

Instead of starting his life as an adventurer in traditional isekai fashion, Kazuma blindly agrees to continue living his life, this time married with Aqua, a punishment they must both share in order to make us all laugh.

Reality is a piece of sh*t. Though rather than rejecting it, Kazuma accepted it, and handle it the way he sees fit. Looking at the fantastical scenery before him, he wonders. And soon found out, that it was all the same. No, it's even worse. But as he said, he would accept it, and handle it the way he sees fit. Particularly this sin he embodies... and its possessiveness. Gugh!

After a series of unfortunate events that transpired while in the Capitol, Kazuma can't help but feel useless and dejected. This is a what if scenario taking place in and after Volume 6 of Konosuba Light Novel so beware of some spoilers. Rated M for some future chapters and to be safe. Kazumin Fanfic.
