Description

In He Who Vowed to Create a Demon Harem, a hero finds himself in an unexpected predicament-falling for the demons he was sent to destroy. Set in 1887, humanity is under siege by demonic invaders, and only the brave warriors known as heroes stand against them. Theo, one such hero, is determined to reclaim the city of Manc from the powerful Halfas family. But things take an unexpected turn when he encounters the family’s daughters, far more captivating than ever imagined.

Thrown together by fate, Theo and three demon girls embark on an epic journey filled with danger, unexpected alliances, and undeniable attraction. Though they start at odds, a mysterious artifact soon helps bridge the gap between them in interesting ways. Will Theo fulfill his mission, or will he succumb to the charms of his former enemies? In this world of magic and temptation, anything is possible.

I'm thankful for the bug fixes and the developers of this game, I've enjoyed playing and it goes down as one of my favorites...I haven't finished the game yet, so these questions may be answered. One thing I was curious as I progressed is what happened to the children after the births? Does the dad and mom of Rose, Layla, and Mia ever make an appearance? One bug that refuses to go away it seems and has the dreadful, "now loading" screen still happens when the MC loses a battle, I really like that in defeat MC can still "help" his harem learn skills/moves.

    The game uses your browser’s cookies to save progress, so your saves might be lost due to:
    • Playing in incognito mode (which doesn’t store cookies).
    • Switching browsers or devices (saves are tied to one browser on one device).
    • The game updating, which can sometimes reset progress.
    • Clearing browser history, which may also delete cookies.
    
    To prevent losing your saves, try playing in a regular browser window, avoid clearing history or cookies, and always use the same browser and device.
