...a school trip... a mysterious light... a fantasy world... monsters and magic... an introverted hero. A simple, familiar plot, with no surprises... and that's fine. No frills, just a classic isekai that ticks all the boxes, just to create clichés of the genre_where it can't. Kaito, a young adult otaku, our protagonist, refuses to play the role of the "typical hero." Armed with a keen critical sense, a wry humor, and a disturbing emotional distance, he explores this universe like a player, but gradually feels the weight of real relationships, real pain... and a past he keeps secret. Between slices of life, quiet quests, deep human connections, and reflections on the meaning of adventure, this story is less about conquering a world than about discovering oneself.

Kaito Ran was only eleven years old when he stood by his ailing father's side and watched him suffer until he passed away. During his passing, Ran witnessed a djinn appear to take his father's soul to hell (NARAKU). Ran refuses, unable to accept his father facing eternal perdition, regardless of the djinn telling him that that was the order of things. At the end of the day, his refusal meant nothing. His father was taken to hell, but during the process, Ran caught a glimpse of hell before the spiritual portal disappeared. He saw that it was a realm, a place of material and magic. He saw nine cities and towers, mythical beings and doomed souls. He realized that he could go there, he could go to hell and rescue his father.

In a world driven with powers, bloodlines, powerful clans and curses, how would a boy seemingly from no origins fare against all of these thrown at him with nothing to help defend against it all.

Xavier wasn't expecting much from today—maybe a boring meeting, definitely some subpar coffee. What he didn’t expect was a silver lance aimed at his neck, a teenage girl with the attitude of a war-hardened NPC, or getting dragged across several floors like a human mop. When an encounter with a very aggressive seventeen-year-old turns into a rooftop revelation, Xavier learns the impossible: he’s an Executioner, born with a power called a Gate—and monsters are out to kill people like him. No, he doesn’t remember signing up for this. Yes, it’s apparently non-refundable. Add in a teleporting hallway, a superpowered girl who clearly skipped the empathy tutorial, and a muscle-bound giant that could double as a building—and Xavier’s world is flipped upside-down faster than you can say, “I’m hallucinating now.” It’s his first day as an Executioner. He’s already regretting everything.

After dying in his previous life, Kaito Nakamura finds himself in a strange new world, free from the weight of past regrets. Surrounded by unfamiliar faces, he begins to carve out a new life, one filled with hope and the chance for personal growth. But as time passes, Kaito soon discovers that this world holds far more challenges than he ever imagined—challenges that test his resolve, his desires, and his understanding of what it means to truly live. In a world where loss is inevitable, Kaito is forced to confront the darkness that lingers within him and the painful sacrifices that come with seeking redemption. Will he be able to rise above the tragedies that define his existence, or will he become a victim of his own unresolved past? MC name: Kaito Nakamura. Age: 17.

After a traumatic childhood, Asta finally managed to regain some sense of normalcy in his life. Unfortunately, life itself had other plans for him. On one truly unfortunate day, Asta was kidnapped by an otherworldly cabal and tortured for six months. By the time he came to his senses, he found that he was no longer a man or even human, for that matter. Now a newly minted dragonoid but still under the control of her kidnappers, Asta must balance living a normal life and enacting revenge upon all those who slighted her. Time and time again, destiny has shackled Asta’s dreams and aspirations, but no longer. A grand evil lurks in the shadows, endangering every world it comes across, and Asta, now Scarlett Nova, must face it or die trying. All things considered, it’s not the worst thing ever. At least she’s got a whole lot of power and her best friend by her side. Author’s Note: This story is Girls Love (WLW). Asta’s personality may feel out of place at times, but I have a special reason for that that I will reveal around 500 or so chapters in the future. Hold your questions for now. As for the first arc where Asta enters the academy as a slave, I understand if many people may have their reservations. Don’t worry, however, as Asta’s slave status is only temporary (until Chapter 40). Thanks for reading! The story chapters are currently being edited by @Xiao Discord: https://discord.gg/jkM2yT79dT

Kaito was just an ordinary office worker—overworked, under-caffeinated, and nursing back pain from a chair he swore he’d replace six months ago. His only escape? Fantasy novels, strong tea, and the quiet hum of a café on a rare peaceful morning. Then came the blinding light. Now? He’s been accidentally summoned to a divine realm by a flustered priestess who mixed up the magical paperwork and pulled in the wrong guy. Oops. Stranded in a world not meant for him, Kaito finds himself face-to-face with a radiant Dragon Goddess named Aurelya—who can’t return him home, but offers him a blessing and a chance to start over in the magical land of Aurethria. Granted the unique skill Scholar’s Insight, which lets him read and understand all magical languages and ancient texts, Kaito begins his new life as a sixteen-year-old bookworm with no combat skills—but an overpowered brain. Can a sarcastic, tea-loving introvert survive in a world of scrolls, spells, and dragons? Can he keep his head down long enough to avoid divine attention? And will the Dragon Goddess ever stop feeling guilty for yeeting the wrong guy across dimensions? A slow-burn, slice-of-life isekai full of magic, mishaps, and unexpected bonds. Because sometimes, saving the world starts with being a cosmic mistake.

"Love Tripped Into My Room: I Just Wanted Peace, Not Panties" Kaito Tenma just wanted a normal life. Wake up, eat toast, avoid drama, and maybe—just maybe—confess to his beautiful, blunt childhood friend, Riko. But fate sucker-punches that dream into space when a half-naked girl crashes through his ceiling and declares his room as her new home. Now he’s living with Yuna, a mysterious (and dangerously clingy) bombshell who thinks clothing is optional and personal space is a myth. From lewd accidents to jealousy-fueled misunderstandings, Kaito’s life spirals into a wild, hilarious mess of high school chaos, horny misunderstandings, and girls who seem way too interested in ruining his peace. He didn’t ask for a harem. He didn’t ask for trouble. But trouble keeps tripping into his life—one girl at a time.

Kaito is the only known human left in a universe where humanity is extinct. Almost everyone wants him dead. But something… or someone wants him alive. He’s hunted by intergalactic governments and haunted by the mysterious power growing inside him. With the help of the S-ranked elven Star Traveler captain Elara and her crew, the Starlight, Kaito journeys across countless worlds, clashing with empires, cosmic well guardians, and the demons of his and the universe’s past—all in search of one thing… The Cosmic Heart. Heart of the Cosmos is a sci-fi, shonen-meets-seinen space opera with martial arts, interstellar warfare, cosmic powers, and emotional moments. *For fans of Naruto, One Piece, Fate, Bleach, and Star Wars.
