Phantom Alchemy ~Silvia's Dynamic Urban Planning~

Sylvia, an ordinary girl living alone deep in the mountains, is visited by a man named Steve and taken to the remote city of Elanberg. There, without understanding why, she is suddenly pushed down and roughly rapes by him. Despite the traumatic first experience, Sylvia soon feels a mysterious power surging through her body—she has unknowingly awakened a hidden talent for alchemy, triggered by semen. Entrusted with developing the town using her new powers, Sylvia must now collect semen from men as her source of alchemical energy. Thus, after bleeding from her lost virginity, the novice big-breasted alchemist Sylvia is born. To fuel her alchemy and grow the remote city, she realizes with dread just how many men she’ll have to take inside her…

Having successfully completed the road construction project, novice alchemist Sylvia heads to the town’s Adventurer’s Guild to introduce herself. There, she meets Irene, the Guild Master. Irene, who deeply respects Sylvia’s mother as her benefactor, warmly welcomes the young alchemist, and the two quickly get along. But just as they’re hitting it off, terrible news arrives. “Emergency! There’s been a cave-in at the western mine!” Sylvia joins Irene and rushes to the scene for a rescue mission. The mine is a dangerous monster-infested area. The trapped survivors are trembling in terror. To give courage to the frightened man, Sylvia uses her own body to comfort him. Even though she gets completely overwhelmed and toyed with as he desperately clings to her in fear, they somehow manage to settle the situation. …Or so she thought. Suddenly, Irene starts acting strangely…
