AURA: Hentai Cards, an interesting mixture of a two-dimensional erotic visual novel and a collectible card title, immerses users in a setting where magic, romance and adventure are seamlessly intertwined. In the kingdom of Pentarull, the looming threat of the Demon Queen's army has been casting a shadow for a century, and only the Alliance dares to stand up to it. However, hope emerges when the goddess Aura chooses a champion to receive her divine power, offering a chance to end the ongoing conflict once and for all.

The life of an ordinary farmer like you takes an unexpected turn when Aura gives you magical powers. Although you do not possess the valor of a seasoned warrior or the courage of a hero, fate has chosen you to play a key role in the unfolding events. Your task in AURA: Hentai Cards is to form an alliance with many beautiful women, forming a formidable harem to resist the demon queen and her forces, or, conversely, go over to her side.

As you travel through the vast landscape of Pentarulla, you'll encounter a vast array of creatures, including elves, beast maidens, and demons, each offering unique challenges and opportunities. Throughout your epic journey, you'll have the opportunity to interact with the locals, delve into their stories, and perhaps find love amidst the chaos. Each harem member you recruit will bring with them a story and special abilities to contribute to your cause, adding depth and complexity to your adventure.
