Spoilers for Vol. 17. Everything is going well in Belzerg after the defeat of the Devil King. Kazuma is living his best life while drowning in fame and glory. But his expectation of an easy life is quickly destroyed as a new quest is bestowed upon the legendary heroes of Belzerg. A sequel to "The Promise".

¿Qué harías si despertaras en un vacío frente a Aqua? Con el cuerpo de Kazuma. Este fanfic está basado en el mundo y los personajes de KonoSuba, creados por Natsume Akatsuki. No tengo ninguna afiliación con los creadores ni con la serie original. Esta obra es puramente una creación de fan y no tiene fines de lucro.

What if, Kazuma never became that smarmy cynical adventurer that we know, but was rather a humble porter, what if Aqua wasn't a goddess, but rather an elemental paladin born of this world, and yet supposably they still wound up being in the same party together. 3 shot

What if Kazuma Satou wasn't a neat? What if he actually tried? This story explores a version of Satou Kazuma that has experienced a different life up to his reincarnation. Join him as he tries to navigate through this unknown world full of monsters and demons along side his party. Will he be able to defeat the demon king and return home? Or will he fail? Only time will tell.

What happens to our boy Kazuma after being the butt end of everyone's joke for the last time and decides he's going to quit school and be a NEET once more. Decided to revive this fic on a whim, and who knows maybe it'll get the ending you all deserve.

Darkness piensa en su mentira cuando dijo que estaba embarazada de Kazuma y piensa si es posible un futuro con el.

Kazuma is on his way home after buying a new video game that came out, when he sees a floating door in the middle of the city. When he opens the door, he sees a dungeon inside filled with monsters and other staple RPG elements. A mysterious app also appears on his phone showing his 'Stats'. This is every otaku's dream come true! (contains sexual situations and harem shipping)

Short story compilation with ties to the sixth 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.

What if Kazuma was the new Demon King? What if Aqua resumed her post in heaven looking for hero candidates from Japan to defeat Kazuma? What if someone named Kazuma Satou reincarnated into a world where the Demon King had the same name as him? What would happen if Satou, Aqua, Komekko, and Iris formed the most overpowered party in the history of the world? Hilarity, of course.

Eris hints to Kazuma that earning a goddess's favor can grant him a hidden stat boost. So Kazuma suddenly becomes very nice to Aqua, and she is too distracted to smell the scheme. But the same is true of Kazuma.

Kazuma's identity as the fearsome masked thief has been exposed, and he is forced into hiding! Darkness cannot save him this time, the Demon King's army is moving into full swing, and the party has no idea where he is. However, he has a few things going for him, including a silver(-haired) lining!

Do you think that Satou Kazuma would live happily ever after once he had defeated the Demon King? Of course things wouldn't be that easy for him! Loose ends all over demand the attention of our favourite protagonist and his party! Set after the end of the LN.

Es la historia de konosuba, pero como el titulo sugiere será con el final feliz de Kazuma con yunyun,

In which Kazuma wizens up rather quickly to the fact that his party members are all idiots and they're doomed if they don't shape up. Perhaps it's time to phone in a couple friends.

Fed up at being left behind in level, Kazuma seeks out a way to earn more exp. Stumbling upon the Lonely Yunyun, he gets what the extra exp, but also something more, something more valuable than just some extra levels (even if he won't admit it to anyone).

A new dark creature stalks Belzerg, striking fear into all who cross her path...in theory. She's just not very good at that yet! But once Yunyun finishes her apprenticeship under General Wiz, she's sure to be an expert at raising zombies, contract negotiations, and logistics and resource management! Right?

What if Kazuma and Luna fell in love with each other after months of flirting, Love awaits those who yearn for it. How would the whole town react to an up-and-coming adventurer on the Rise like Kazuma court and attract Luna, one of the well-known Guild Staff Members of Axel? It seems like an almost contradiction

Kazuma, a hardworking engineer, gets teleported to another world by Aqua, the goddess, to eliminate the Demon King. He makes new friends and eventually, Aqua joins them, making for a humorous and fantastical team.

After a deadly encounter with the Demon King's #1 assassin, Kazuma is forced between two options, permanently cease to exist, or become a devil. However in classic Kazuma fashion he's obviously too scared to choose to die himself. So now he's immortal and he's making sure that's now everyone's problem.

Kazuma Sato has spent the last 4 years of his life as a typical Japanese NEET, unable to escape the feeling that somewhere, somehow, his life went wrong. But one night, he learns that destiny will only be put off for so long... Some post Vol 15 elements used, fair warning.

A certain memory popping up in Kazuma's mind in the split second before he unlocked the vault's door, leads his encounter with Sylvia down a very different path. My first ever fic, criticisms welcome.

"Si miras a una diosa con lujuria, una terrible maldición caerá sobre ti... ¿Lo oíste verdad? ¡No finjas que no me escuchaste! ¡Kazuma!"

THIS FIC CONTAINS LN SPOILERS! One-shot. Kazuma fails to kill the demon king with his explosion, so Aqua avenges him. Don’t worry about edginess, it’s lighthearted.

A Kazuqua fan disguising his favorite ship as factual history using his position within the axis order, witness cringe as you read his accumulated research into the konoverse mixed in with history he has tampered with to push his favorite ship and all the multiverse shenanigans he discovered!

The sixth volume of the series.
