Promestein

Promestein is one of the main antagonists of Monster Girl Quest. She is an angel who devotedly follows Ilias's cause without question.

Creating many great pieces of technology, including the experimental technology used by Chrome and Lily, as well as the Artificial Spirits, Promestein can be seen as the mastermind behind many of the plot-related hinderances to Luka in both chapter 1 and 2.

Promestein is most commonly seen wearing a labcoat.
