“She fell from the sky. Crashed through my ceiling. Made me her slave. …I said yes. Because why not?” Kaito Ren is your average NEET—with abs, attitude, and absolutely no ambition. One sleepless night, a stunning goddess crashes into his life—literally. Thanks to a cosmic screw-up, he’s now bound by a divine slave contract that grants him insane powers… at the cost of his soul. Now armed with glowing swords, a cursed gun, and a blacked-out Yamaha R6, Kaito tears across dimensions—hunting devils, fighting gods, and rewriting destiny itself. He flirts with the very goddess who owns him, pisses off divine pantheons, and aims to become more than just a slave. He wants to become the most overpowered rebel the heavens have ever feared. 1. Magic. 2. Devil hunting. 3. Bike chases. 4. Flirty tension. 5.Mortals vs Gods. The divine messed up… and chose him.

In a world overrun by dungeons, everyone awakens with a System linked to their destined class. The strong become Hunters. The weak become corpses. Kaito Ryu has no System. No class. No future. Mocked as a dungeon janitor and discarded by society, he’s barely surviving—until a betrayal leaves him bleeding out in a dungeon’s depths. That’s when something inside him snaps. SYSTEM ERROR: Class ‘None’ rejected… Assigning forbidden class: [DEVOURER]. Now, Kaito can absorb the abilities of monsters—and humans. Strength. Speed. Magic. Even memories. But with each skill he devours, something darker stirs inside him. Will he rise as humanity’s savior… or become its worst nightmare?

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.

He just wanted a new start. Instead, he got two stepsisters, an ex-best friend hiding something, and a love tangled in secrets. Red Eyes, White Lies follows Kaito as he transfers to a new school — only to find himself surrounded by unresolved pasts, dangerous truths, and a growing romance he can’t escape. Love, betrayal, family — and the lies we tell to protect it all.

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.

Kaito Tanaka, a high schooler whose kindness is both a superpower and a crippling curse, just wanted a peaceful school life. But when his simple acts of decency are wildly misinterpreted by the school's tsundere ice queen, his possessive childhood friend, a shy bookworm, a fiery sports star, and even four of his own teachers, he finds himself at the center of a harem. The catch? They all despise each other, and Kaito's life has become a 24/7 battlefield of jealousy, comedic misunderstandings, and ridiculously ecchi situations.

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.

On an ordinary day in modern Japan, a group of high school students finds their lives shattered when their classroom is engulfed by a blinding light and monstrous attack. Transported to Elynodor, a mysterious and fantastical world ruled by magic, dragons, and ancient spirits, they are thrust into a destiny none of them chose. Guided by enigmatic mentors like Miss Eira and Master Arven, the students begin their journey of survival—training to awaken powerful elemental abilities to fight back against the looming threat that stalks this world. As each student discovers their affinity—some blessed with rare and powerful combinations—one boy stands apart: Kaito Ryuudou, the only one who manifests no power at all. As friendships are tested, truths unravel, and a dark prophecy looms, Kaito must face the question that haunts him: Is he truly powerless… or is something far greater slumbering within him? In a world where the line between life and death is drawn by magic, will these students rise as heroes—or be claimed by the very forces they were summoned to fight?

Kamakura Metropolitan University practically worships its resident bad‑boy brood: Akuma Takashi and his hand‑picked trio—Tomo Aizawa, Reiho Tsukishima, Itsuki Moriyama, and Takumi Kisaragi. Handsome, untouchable, and forever bored, they survive on one intoxicating pastime: reckless bets. The whole campus swoons over them, yet something about the quartet feels… off—too polished, too predatory, almost supernatural. It’s a sun‑soaked Thursday when trouble finds them. Akuma lounges in the cafeteria, annotation pen hovering over a battered paperback, when Tomo drops into the seat opposite, eyes gleaming. “Bro,” he drawls, “bet you can’t make the very next person through that door fall hopelessly in love with you.” The glass doors hiss. In walks Kaito Ishikawa—hood up, earbuds in, radiating I‑dare‑you apathy. Once upon a freshman year, he was Reiho’s favorite target; lockers, insults, sucker punches—Kaito endured them all with a single bored blink and a muttered expletive. Reiho flinches at the memory. “Bad call, Tomo. The guy’s got ice water for blood and a tongue like barbed wire.” Itsuki arches a brow; Takumi gives a low whistle. Tomo just smirks wider. Akuma snaps his book shut, eyes tracking Kaito’s deliberate stride. A lazy, dangerous smile curls across his lips. “Challenge accepted,” he murmurs— and in that heartbeat, the game is on. Akuma Takashi is the very definition of breathtaking. With white marble hair that dances with the wind and ocean-blue eyes that could drown you without warning, he’s the kind of beauty that makes people stop mid-step—and girls quite literally beg for his attention. He’s tall—like, stupidly tall—standing at a striking 180 cm, and he knows how to use every inch of it. And then there’s Kaito Ishikawa—just 165 cm of pure, concentrated menace. A short, sharp-tempered little villain, armed with jet-black hair, deep brown eyes, and zero tolerance for bullshit. He’s either buried in a book or glued to his phone, rarely acknowledges class, and yet… he’s always topping the academic charts. How? No one knows. Why? No one dares to ask. Frankly, no one cares—because Kaito doesn’t give a single damn about being understood. He’s chaos in a quiet package. And Akuma? He might be the only one insane enough to unwrap it.

...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.

In the bustling city of Tokyo, where people pass each other unnoticed, Kaito Renji harbors a secret that cannot be ignored... He has no shadow. Living an ordinary life with his parents and sister, Kaito hides behind a fake smile, pretending to be normal in a world that shows no mercy to those who are different. But when a series of strange murders spreads across the city and an inhuman creature appears in the darkest corners, the truth begins to crawl toward him—just like the insects that creep through the cracks. In a world devoured by betrayal and deadly secrets, the shadow may be the enemy… or the key. As Kaito’s true identity comes to light, he realizes Tokyo is not just a city—but a vast web of lies. And he was never truly human… but something the insects have followed in silence all along. When the darkness begins to move, no one escapes without losing a piece of their soul.

Kaito’s life sucked. Missing parents, no friends, and zero reason to keep going. That is…until he woke up as a black house cat with a sarcastic system glued to his face.

Stop the end of the world…or die trying~

But he's not a bloodthirsty warrior, nor a ruthless conqueror. He's... lazy. Lazy, perverted, peace-loving, and only cares about sleeping, eating, and—maybe—flirting a little. Carrying the forbidden ability [Devourer], capable of absorbing the powers of any creature he consumes, Kaito also possesses within himself the Seven Deadly Sins, sealed by mystical chains that threaten to destroy his sanity if broken.

Between conflicts with sacred heroes, demonic politics, magical chains, legendary monsters, and extremely embarrassing situations at home, Kaito only wants to know one thing: "Is it possible to save the world... without getting out of bed?"
