Futa Concoction -Halloween Special- -Faust Seiker- is not for everyone. It requires a specific palate—one that enjoys surrealist horror, explicit anatomical humor, and visual novels that break the fourth wall like a pumpkin through a window.

If you have the stomach for it, brew this concoction. Just don't drink it.

The Witch's Brew of Futa Village - A Halloween Tale

In the quaint, mist-shrouded village of Futa, nestled between the whispering woods and the eerie mountains, there lived a notorious alchemist named Faust Seiker. Renowned for his unparalleled skill in concocting potions and elixirs, Faust was both revered and feared by the villagers. His latest creation, however, was shrouded in mystery and seemed to hold an otherworldly power.

As Halloween approached, the villagers of Futa prepared for their annual masquerade festival, a night when the veil between the worlds was said to be at its thinnest. Faust, intrigued by the legend of this night, decided to concoct a special brew. He gathered rare, glowing herbs under the light of the full moon and mixed them with essences of shadow and flame.

The potion, known as the "Futa Concoction," was said to grant the drinker unimaginable power for a single night—a night where one's deepest desires could be fulfilled, but at a steep, unpredictable price. The villagers, eager for a taste of the divine or the demonic, gathered at Faust's tower, each with their own reasons and desires.

Among them was Emiko, a young woman with a wish to heal her ailing mother; Taro, a brave warrior seeking invincibility; and Lila, a mischievous witch looking for a thrill. As they gathered, Faust revealed his creation—a glowing, ethereal liquid that seemed to shift and shimmer like the night itself.

With a sense of trepidation and anticipation, they drank the Futa Concoction. At first, nothing seemed to happen. But as the clock struck midnight, each of them began to feel an energy coursing through their veins, an energy that manifested in different ways.

Emiko found herself surrounded by a healing light, her mother's illness vanishing as if by magic. Taro felt his muscles strengthen, his senses sharpen. Lila, however, found herself transforming, her body shifting into a form both powerful and terrifying. By Alchemical Arcana Magazine When the industry of

As the night progressed, it became apparent that the Futa Concoction had granted them more than they had bargained for. Emiko's healing came at the cost of her memories; Taro's invincibility turned him into a creature of unyielding rage; and Lila discovered she could control the very shadows themselves, but at the cost of her physical form.

Faust watched with a mixture of awe and horror as his creation unfolded. He realized too late that the true power of the Futa Concoction was not in granting wishes but in revealing the deepest, darkest desires of those who dared to drink it.

As the first light of dawn approached, the villagers returned to their normal forms, each bearing the consequences of their desires. The festival ended in a somber mood, with a newfound respect for the power of alchemy and the dangers of meddling with forces beyond human control.

And so, the legend of the Futa Concoction spread, a cautionary tale told around fires on Halloween nights, reminding all who heard it of the unpredictable nature of power and desire.

What sets this special apart from cheap porn parodies is Seiker’s signature dialogue writing. The Halloween Special is genuinely funny.

One scene involves Elara trying to explain her situation to a headless horseman who keeps asking for directions. Another involves a trick-or-treater who mistakes the bubbling, phallic-shaped cauldron for an avant-garde decoration.

Seiker uses body horror not to disgust, but to highlight the absurdity of shame. The game asks: If you grew a third eye on your hip, would you be more afraid of the eye, or of your neighbor seeing it? Available from October 25th – November 5th only

The "Futa" element, while titular, is treated with a bizarre maturity. In this special, it becomes a vector for power. The pumpkin-spiced mutation grants the afflicted the ability to literally "cut through" magical barriers (yes, that is a gameplay mechanic). The Halloween special includes a stealth segment where you must use your... assets... to pick a lock. It is as ridiculous as it sounds, and it works.
