Renseijutsushi Colette no H na Sakusei Monogatari

This is an anime adaptation of Acerola’s video game.

Colette and Priscilla are two alchemists living in the mountains. Priscilla leads a remote life and shares some of her knowledge with her student Colette.

One day, a stranger appears on the threshold of Priscilla to tell her that she must leave the mountain, thus leaving all the responsibilities to Colette. However, Priscilla invented her own alchemical formula, in which she uses the seed of men. Although Colette already has excellent alchemical skills, the collection of the seed has puzzled her. Thus, Priscilla decides to give her student one last lesson with the intention of helping him.
