Hermes

Hermes was the supervisor of Promestein hundreds of years ago when she worked as a clerk and secretary in one of Heaven's libraries. Promestein's questionings of the how things in the world worked would be dismissed by a universal answer of "through the benevolence of Ilias", and these questions would frequently annoy Hermes. She appeared in a flashback in Promestein's past.

In Monster Girl Quest Paradox she is mentioned by Promestein after Luka meets her in the second Tartarus and is yet to make an appearance in Part 3.
