When Kaizen, a struggling nobody, stumbled upon an ancient relic buried deep within a forgotten dungeon, his entire world shattered and rebuilt itself.

A voice whispered in his mind.
A screen flickered before his eyes.

[System Activated.]
[Progression Unlocked.]

From that moment, Kaizen could see his stats, abilities, and quests like a game. Every battle, every choice, every sacrifice leveled him closer to greatness.

But power doesn’t come without a price.
The stronger he became, the more eyes turned toward him—necromancers with their alluring secrets, cunning dungeon nulls who offered him fantasies beyond imagination, and enemies who wished to steal his relic for themselves.

As Kaizen carves his way up through dungeons, realms, and forbidden magics, he realizes one thing:
Heroes aren’t born… they’re forged through blood, trials, and desire.

Will Kaizen rise as the Eternal Hero the world has been waiting for, or will his own growing harem of allies, temptresses, and betrayers drag him into ruin?

Hey everyone, 👋, before diving into the story, I want to be transparent with you. This series was written with the help of AI tools. Why? Because I had so many ideas in my head but needed a way to organize them, bring them to life faster, and make sure nothing was lost in translation.


I know some readers might feel strange about this, and I understand. That's why I'm apologizing in advance if it takes away from your enjoyment. My intention was never to "cheat" but to create. Every arc, character, and twist comes from my imagination — the AI was just the keyboard I typed on, the paintbrush I dipped into.


thank you for giving this story a chance. 


This story contains ecchi-style elements (suggestive themes, fanservice, and occasional sexual humor) in line with anime tropes. These are not the focus of the plot but are included for character dynamics, comedic relief, and world-building flavor.
