My Overpowered BookKeeper System:Starting With The Strongest Talents - Chapter 9…..Illusions of a Perfect Life

​The world, Earth, was devastated by the Great Incursion, an apocalyptic invasion by dimension-hopping monsters. Humanity's only hope now lies in Galaxy Fall, a newly accessible parallel world where they can gain strength through a System of quests and missions.​Five hours after the Invasion, the betrayed survivor Mirabella is mysteriously reborn and gains a unique power: the [Master Account System].Her initial skill is the deceptively simple but devastating 'Multiplier x100', which applies a 100 times buff to all her offensive capabilities, including physical attacks, spirit energy skills, and damage-over-time effects.​Mirabella must now transform from a silent survivor into the world's most feared warrior, who was only scared of one thing, which is?“I Hope I don't run out of opponents in Both worlds.”

Poisoned by his wife, betrayed by his best friend, and abandoned by his children—Matthew died broken and alone. But when he wakes up thirty years in the past, trapped in his eighteen-year-old body, everything changes.Now, the halls feel haunted, memories from a future that may never come keep popping into his head, and something strange is growing inside him—something he can’t explain. Sadly, this second chance isn’t a blessing. It comes with a price.But this time, he won’t be the victim. This time, he’s the one in control.

When a prostitute dies and awakens in the decadent golden city of Prismillya, he finds himself at the bottom of a brutal underground caste system where slaves are ranked, owned, and traded like currency. Reborn in the delicate, cursed body of Loona—a femboy succubus marked as “Guttermeat”—he’s locked in the lowest level of a prison brothel-city ruled by lust, power, and cruelty. But Loona has one secret: with every body he conquers, he steals a piece of his partner’s strength.Armed with wit, seduction, and a thirst for revenge, Loona decides he won’t just survive this hell—he’ll fuck his way to the top.------------------------------------------------------------------[WARNING: R18+ CONTENT INCLUDED]Additional tags: Dark Fantasy, Femboys, Erotic Fantasy, Smutty Isekai, Gothic Dystopia, Prison Break, Queer Fantasy, Slave System Hierarchy, Fantasy Erotica, Magical Realism

I’m a high school student who became an author after debuting at Dengeki Bunko. After taking a year of hiatus from school to write my work, I transferred out to another high school to study, and met a girl called Eri Nitadori in school, a rookie voice actress cast as a character in the anime adaptation of my work.

In school, we treat our professions as a secret. However, Nitadori’s very popular in class, and I’m a loner…the only chance we get to talk to each other is when we take the Limited Express train together every Thursday, seated side by side as we head off for an anime, After Recording.

To improve her skills, she asked me questions regarding the profession. While I was answering the questions regarding the process–how did it end up like this.

This is what I last remembered before I lost consciousness, and the story of my near-death experience.
