Ennis

Szilard's homunculus, though not his first creation. She was created to unthinkingly execute his every command; recently, however, she has been gaining emotions as well as independent thought, as a result of 'devouring' an alchemist threatening Szilard's life.

She later helps Firo, giving him the necessary knowledge to destroy Szilard, and afterwards moves in with him as his roommate.

Ennis eventually reciprocates Firo's feelings, marrying him in the 1980s and taking his surname 'Prochainezo'; two decades later, the couple honeymoon aboard the cruise ship Entrance in 2002, with Czeslaw tagging along.
