Sylvia is a very ordinary girl who lives alone deep in the mountains. Led by a man named Steve who came to visit her, she finds herself in the remote city of Ellanbelk. Then, without understanding why, Sylvia is pinned down by Steve. “Why? I should have hated it…” Before she can even begin to feel down about her disastrous first experience, Sylvia senses a surge of power rising from within her body. She possessed a talent for alchemy that even she herself did not know about. Having awakened to alchemy through the semen, Sylvia was entrusted with the task of using her powers to develop the town. Thus, Sylvia began collecting semen for the sake of alchemy and the town's development. With the shedding of her virgin blood, the new, busty alchemist Sylvia is born! What? The semen she absorbs into her body is the source of her alchemical power? To develop this remote town… how many men will I have to… ugh…?
