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.

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.

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?

As he navigates dungeons, deadly politics, and divine conspiracies, each arc introduces a new heroine with her own dark past and burning desires. But not all is pleasure and paradise.

Kaito's life was a slow fade, his youth stolen by a terrible, incurable disease that left him bedridden for most of it. His only comfort, his only way to connect with a vibrant world, was a full-dive VR reality headgear. It was actually medical gear, meant to help bedridden patients live in a digital world, but for him, it became everything. Inside that digital realm, the game SpellxEdge Online was Kaito's sole escape from his hospital bed. He poured his whole life into it, becoming the top player, ranking number 1 for consecutive years on the global arena across all servers. Then came the night the new server was released. Kaito, eager for new challenges, immediately put on his headgear and logged in. But the moment the device glowed, his body shook, and he died right there while wearing it. The next thing he knew, he woke up in Arcensis, the fantasy world where SpellxEdge Online's story mode happened. A System greeted him, telling him that gods were watching, and they all had different ideas about his new life. Some felt pity, others found him amusing, and some actually wanted him to fail in the world he'd grown to depend on. But no matter what they wanted, all the gods expected him to try his absolute best with this unexpected new chance. Thrown into this digital world as just an extra, Kaito was forced to start from rock bottom and work his way back to the top. He soon spotted many of the main cast from the game's story, from the powerful Grand Master to various professors and villains. But what Kaito really hated were all the super generic plots and characters in the game. He absolutely despised the relentless positivity and cheerful attitude main character who smiled through every problem, the ever-likable childhood friend who always liked the MC but never got him, the rival who was the total opposite of the MC, and the female lead stuck between the two. What challenges will Kaito face in this new reality? How will he grow stronger, and can he truly escape his fate of being an extra stuck at the bottom?

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.

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.

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~

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.
