Sylvia is a very ordinary girl living alone deep in the mountains. Led by a man named Steve who comes to visit her, she arrives at a remote city called Elanberg. Then, without really understanding what’s going on, Sylvia is suddenly overpowered by Steve. “Why…? I shouldn’t want this…” Before she even has time to process her terrible first experience, Sylvia feels a strange power welling up inside her body. Unbeknownst to her, she possesses a talent for alchemy. Awakened to alchemy through semen, Sylvia is entrusted with using that power to help develop the town.

What, the semen absorbed into her body is the source of her alchemical power? To develop this frontier city… just how many men will it take…?
