Era of Castles: Starting with 99 Dragon Eggs - Chapter 478

Over a million years ago, the first human contracted with the first Spirit. Ever since then, Spirit use has become commonplace. Humans used Spirits to carry items and start fires. Eventually, even start wars. Thousands upon thousands of years past and one day, one human did the impossible. He transcended his mortality and ascended to the realm above.

He was the final boss.The monster at the end of the world.The unbeatable nightmare humanity couldn’t kill.Then one day… he quit.Why?Because he saw two hunters having sex in his dungeon and realized Earth might have something way better than world domination.Now, disguised as a “totally normal guy” working at a sketchy restaurant, the most overpowered being in existence is on a personal mission:Sleep with every type of human woman.Catgirls? Yes. Elves? Hopefully. Tsundere sword babes? Absolutely.But hiding his god-level powers isn’t easy—especially when:His cooking accidentally gives people magic orgasmsAn E-rank hero gets famous for “defeating” him (total accident)Women keep throwing themselves at him... and monsters do tooAnd a suspicious ex-goddess shows up asking why he’s working night shifts at a ramen shopHe wanted pleasure.He got a restaurant job, a harem of disasters, and a world that keeps trying to make him a hero.This is not how conquering Earth was supposed to go..__________________________________No NTR, No Yuri

They say meeting your soulmate is destiny, a beautiful collision of two worlds meant to be together....But why did my “fated encounter” have to be a head-on collision with Cassidy Valentine, the most hostile, entitled, and terrifying girl at Hartwell Academy? And why did it involve ruining her limited-edition blazer with cheap bodega coffee?I'm Isaiah Angelo. I run on three hours of sleep, instant caffeine, and the desperate need to secure a future for my little sister. I don't have time for drama. I definitely don't have time for romance.So, naturally, the universe decided to play a cruel joke.I didn't just make an enemy of one rich girl. I stumbled into the lives of four.The Valentine Quadruplets. Identical faces, four distinct flavors of trouble.Now, I’ve been hired as their live-in personal assistant. I’m trapped in a mansion with the four most desirable—and impossible—girls in the city.Cassidy, the “Problem Child” who has sworn to make my life a living hell.Harlow, the overly affectionate airhead who thinks snacks solve all emotional trauma.Vivienne, the ice-cold perfectionist who wants to micromanage my breathing.Sabrina, the silent observer who looks at me like I’m a puzzle she’s dying to solve.The pay is life-changing. The job is suicide.Can I keep my scholarship, raise my sister, and manage the chaos of the Valentine household without losing my mind?I have a mountain of debt, a schedule from hell, and four billionaire heiresses who suddenly seem very interested in the “scholarship boy.”This isn't a job.This is a survival horror game wrapped in silk sheets.WHAT TO EXPECT:- Ecchi Situations: The Valentines have zero concept of personal space, and the “accidents” are frequent, spicy, and very visual.- Harem Romance: Four identical sisters, one tired protagonist. The competition is fierce, the tension is high, and the jealousy is real.- Competent Protagonist: Isaiah is smart, hardworking, and sharp-tongued. He isn't dense; he's just too exhausted to deal with their thirst.- Class Gap Dynamics: A gritty look at the difference between the struggling working class and the absurdly wealthy elite.- Heartwarming Family Moments: Because behind the fanservice and comedy, Isaiah is doing it all for his little sister.
