Lust System: Monster girl Harem - Chapter 1 - Graduation

Notice: This story contains R18+ themes, including violence, sensual and sexual content, blood-related addiction, and dark psychological elements. Reader discretion advised.I died in a library, crushed under centuries of forgotten knowledge. Fitting.Now I’ve woken up in a coffin, starving, undead, and very much not human.They call me a Fledgling—a bottom-feeder vampire barely above a ghoul. I’m weak, hunted, and tethered to a world straight out of a cursed tabletop campaign. It’s a classic fantasy realm—elves, knights, guilds, and dungeons—but twisted by a dark, rotting magic. The moon shines red, the gods are silent, and every town smells like fear.To make matters worse, I’ve been bound to a LitRPG system called the Blood Codex.Level up by draining blood.Unlock skills by embracing your monstrous nature.Resist Corruption... or don’t.There's no prophecy. No chosen one nonsense. No noble title. Just fangs, rot, and whatever I can steal, trick, or kill to survive.But the deeper I sink into this world’s underbelly, the more I realize something is watching me through the system. The rules are breaking. Dungeon bosses are going mad. Entire towns are disappearing.And I think I’m supposed to fix it… or maybe finish the job.

[From the Author of Author's POV...]

Emotions are like a drug to us.

The more we experience them, the more we become addicted.

The hardest part is not letting them consume us.

But it's already too late for me.

I've already been swallowed whole.

***

I had no knowledge of the game.

I was meant to have died.

And yet, I found myself in this situation.

A game I had never played before. A character I was unfamiliar with, and... A world that seemed to want to swallow me whole with every move I made.

What the hell is going on?

...and who am I?
