Synopsis

Natsuki Subaru’s life has never been easy, weighed down by low self-confidence. When he is suddenly sent to another world, instead of feeling giddy like a typical isekai protagonist, he is utterly terrified.

The reason?

He now carries the memories of a man named Ayan Ghosh, and through those memories he learns that he is essentially the main character of an anime.

With no choice but to move forward into his bleak future, Subaru resigns himself to endless suffering—dying again and again, cursed with Return by Death, and haunted by the obsession of a yandere witch. Yet this time, something is different. With every death, he grows stronger… but why?

…

In this story, Natsuki Subaru is the fusion of two souls: one from a world where universes like Re:Zero, Marvel, TTIGRAS, DC, Danmachi, and DxD are mere fictions, and the other being the original Subaru himself. Together, they form a new identity—Zero—possessing the traits of both and two abilities: Subaru’s Return by Death, and another, mysterious power known only as [Redacted].

★ 4.8

Adamos_Amet

Marked by the cursed Darksign, Naruto Uzumaki finds himself tethered to two worlds: the unforgiving lands of Dark Souls and the shinobi realm of ninja. How will a world of Dark souls face a Chosen Undead with chakra? And how will the shinobi world confront a warrior reborn in the Lands of Lordran?

Book 1: https://www.amazon.com/dp/B0G4HJDQNH

Ludger was supposed to be just another forgotten soul, reborn into a quiet life under the care of his young mother, Elaine. With nothing but a mysterious system in his vision and the faint promise of growth, he resigned himself to learning the humble trade of cooking. Knives, fire, seasoning—his skills grew sharper than his years, but it wasn’t the power-fantasy adventure he once dreamed of. That is, until one reckless night in the tavern, when a hooded mage and a simple spell shattered the illusion of normalcy forever.

Marked by the system as a prodigy, Ludger finds himself juggling more than just knives and plates. Every Job, every Class, every Master holds a new path forward, and he refuses to let his second life waste away like his first. From kitchen tricks to forbidden magic, his journey forces him to carve out his place in a world that rewards ambition—but punishes those who rise too quickly. Allies, enemies, and masters appear in unexpected places, and Ludger soon learns that every choice he makes reshapes not only his future, but the balance of power around him.

What begins as the daily grind of a precocious child slowly transforms into the legend of a boy who refuses to follow anyone’s script but his own. With wit, stubborn pride, and the determination to never be helpless again, Ludger steps onto the path of true ascendance—one coin, one skill, and one risky gamble at a time.

Naruto: The Live-Stream Shock, Konoha Sees Two Destinies!

★ 4.8

J_Dragon

During the Chunin Exams, a mysterious live stream hijacks all screens, revealing two impossible lives of Naruto Uzumaki.

In one world, the despised Jinchuriki rose to become Hokage through unshakable will and talk-no-jutsu. In another, a calculating Naruto, aware of his origins from the start, single-handedly revived the Uzumaki clan—not for Konoha's sake, but for its eventual reckoning.

The revelations send shockwaves through the afterlife and the living:

Tobirama: "This boy was born evil! And he dares to court Tsunade?!"

Hashirama: "Tobirama... we're dead. And I'm more concerned about the 'reckoning'."

Madara: "Black Zetsu, explain. Now. Or disintegrate."

Kushina: "That's my boy! The Uzumaki will rise again!"

Minato: "So... my son is leading a clan revival. Am I a Senju now?"

Kaguya: "The logic of this mortal's ambition... I comprehend. But why am I involved?"

Lilith: Origin of Succubi

★ 4.6

Saine

I woke up naked and all alone in a summoning circle, the only clue to my past is a demon summoning book and the hazy memories of a world very different from the one I find myself in now. I should probably be more concerned with the changes that have befallen me but I can't help but be excited to explore this new world with the new lovers I've found. After all, I'm apparently the Origin of Succubi, my actions will shape my new race in this world and all I know for sure is that I'm horny as hell.

I update twice a week on Sundays and Wednesdays!

Note: This novel contains a rape scene early on in chapter 8, this is not a frequent occurrence and it is not glorified or treated lightly. This is an event that affects the protagonist though so there are occasional references and allusions to the event throughout the series. The novel is loosely a genderbender but the Trans tag is for a character other than the protagonist.

The series primarily features anthropomorphic characters including the protagonist which may be a turn off to some readers. The references to things like snouts and muzzles happen relatively rarely though, so you may be able to picture the characters as monster girls instead.

The cover art was drawn by myself.

Black Witch from Another World

Chaaruzu_Corner

"Overlord that isn't too dark." My first idea of the story.

A man by the name of Rin, a 30 something year old professional gamer, dies by accidental lightning from god while playing the VRMMO game, "Endless World Online" and wakes up in another world inside his girl main character Morus.

Now how do I rise up without people finding out my abilities?

He or she now carefully and cautiously lives in this new world without causing suspicion, chatting with god, and finding his purpose in this new world.

John was just your average old man. He had always worked hard, had a wife, kids, family. A good life.

Then one day, at a crosswalk, some kids were not paying attention and tried to cross. A truck was barreling down the street and John didn't hesitate and jumped in front of the kids and threw them out of the way. Along with his back. The truck slammed into him and the world went black.

When he awoke, he was in a circular room, golden and silver lights flashing around the floor. Ten doors were lit up on the wall behind him and a man was on a dais in front of him, head looking up, arms out wide like some type of showman.

"Welcome kids to your new life as a DEN protagonist, you will be competing against other groups in various anime, vide- wait who are you?"

"My name is John, who are you? And what is anime?"

Follow our new protagonist while he ventures into new worlds he had never even heard of before and tries to survive.

Things to note about this novel.

He is an old man, and they didn't give him a young body, they just did some minor cosmetic and physical changes. He will get some bonuses as he progresses, but he will never be the 18-25 year old ripped MC, even if he replaces a MC who is that way. (But maybe he will be like Silver Fang from OPM, who knows)

He has no idea about anime, or any world he is entering, just some knowledge about life for living for 80 years. I'll be forcing some canon scenes but there is a reason for it.

MC will be hopping worlds fairly frequently.

He will not be OP out of the gate, he will be training, and recovering, a lot.

This will probably be a slow burn for smut. I plan on keeping the harem down to no more than 2-3 per world as that will be hard enough to keep up with once the story develops. I reserve the right to change my mind on this though =)

The DxD world isn't for a long time. And no he isn't replacing Issei.

I am writing another novel concurrently to practice different writing styles before I work on my original novel. Check out My F-Grade Reincarnation.

1-2 chapters a week, approx. 2500 words each.

I want feedback. Good, bad or ugly. Preferably constructive as I can't do much with "This is a terrible novel. Dropped." 4-5 stars always appreciated though.
