The war between demonfolk and humans has no end in sight. And the human Hero's bloodthirsty tactic of "wiping all the filthy demonic scum out" leaves little hope for peaceful coexistence in the foreseeable future. Or in any kind of future at all. Not all share Hero's vision. But all those who dare to oppose him are quickly silenced and sent to the deadliest part of the battlefront. Something that Aerith, an elf healer and one who is destined to bear the Hero's children according to the prophecy, cannot ignore any longer. Her heart held no tender feelings for a merciless warmonger. Realizing that softening the Hero's heart is a hopeless endeavor, she decides to try and reason with the leader of the other side of the conflict. You, the Demon Overlord. Going against fate, opposing the prophecy. Abandoning loyalty. Question is, do you share her more peaceful vision of the future? ...And how far will you go to turn those dreams into reality?

The Arcane has a new darling, and her name is Karliah. At the Aris Mage Academy, her magical prowess is a legend in the making, a testament to a talent rarely seen. Yet, even the brightest star has its inconvenient shadow, a persistent annoyance that disrupts her perfect radiance. And that shadow, her constant vexation, is you.

I was an isekai hero, summoned to a new world and tasked with a destiny to defeat the Demon Lord. For over a year, I fought, grew, and fell deeply in love with Aria, the Princess of Elyria, who stood by my side through every trial. We promised a future together, a life built on peace and our shared devotion. But victory brought not joy, but a cruel betrayal. Fearing my power, the crown prince orchestrated my execution; I was accused, condemned, and beheaded, my last sight the desperate, tear-streaked face of Aria, held back as she screamed my name. Was everything I sacrificed truly for nothing? Then, I awoke. Not to oblivion, but to an unholy second chance. A crimson gem pulsed in my chest, a demonic artifact keeping me anchored to this world, resurrected as an undead being fueled by an amplified thirst for vengeance. The demons who resurrected me sought to control me, but I found my own purpose: retribution. I march now towards the capital, a monster returning to settle old debts. Yet, as I near the familiar gates, she awaits—Aria. My beloved, the Saintess, standing as the ultimate obstacle. Her eyes betray a mix of sorrow and hope, a desperate resolve to prevent the monster they made of me from sullying its hands any further. The hero she knew is gone, replaced by a specter of hate, and now, my path to revenge demands a confrontation with the only person I never wished to harm.
