A young hero is determined to free a city conquered by demons in AVANTGARDE’s He Who Vowed to Create a Demon Harem, now available on DLsite with an AI translation patch.

He Who Vowed to Create a Demon Harem is a fantasy RPG taking place in a world invaded by demons. After an era of peaceful existence, humans have been attacked by armies from Hell. Thankfully, the gods didn’t ignore their plight and have sent down mysterious weapons meant for combating the devils. Those who come in their possession and learn to fight against monsters become known as heroes, the defenders of humanity.

The story’s protagonist is one such hero of little renown. He graduated the academy with average grades, wielding a mysterious weapon in the form of a collar whose effects haven’t been discovered during his training. To make a name for himself he decides to free the city of Manc, ruled by the demon family Halfas. He soon meets one of the demon nobles ruling over it, but loses the fight, jumping onto a passing cart to escape. In the cart itself, he finds another female demon.

His second encounter with a demon isn’t as bad, as she has no intent to fight him. During their short exchange, he blurts his wish to see the girl’s panties, which activates his mysterious collar, forcing her to obey. Discovering that he can control female demons with his artifact, he sets his sights on Manc once again, feeling confident that he could win the city back, if he can master his new powers.

The game features quests, exploration, and turn-based combat standard for role playing games. During their journey, players will meet three demon heroines from the Halfas family: Layla, who’s secretly interested in humans; the shut-in Mia; and the aloof Rose. Players will have numerous occasions to abuse these demon girls using the hero’s powers, which will change their stats and attitude, slowly making them attached to the hero. There are 40 base CGs to discover throughout the story and its five endings.

He Who Vowed to Create a Demon Harem is now available on DLsite for the promotional price of $11.95 USD (estimated from ¥1,584) until February 13th, at which point it will cost $14.94 USD (estimated from ¥1,980). After purchasing the game, the English translation patch has to be downloaded separately from the store page.
