Ennis Prochainezo

"Could you please listen to this selfish request of mine? Please ... don't forget about me."

- Ennis to Isaac and Miria Ennis is a major protagonist in the light novel and anime series Baccano!. She is a homonculus created by the immortal scientist Szilard Quates, and was his servant until he was killed by Firo Prochainezo, whom she would later marry.

She is voiced by Sanae Kobayashi in the Japanese version of the anime and Brina Palencia in the English version, the former of whom also voices Allen Walker.

History
While she was initially emotionless, Ennis gained human feelings after being forced to absorb an alchemist for his knowledge, learning empathy and morality in the process for the very first time. Wrecked with guilt over what she had done, she was nevertheless forced to continue obeying Szilard, as he could kill her with a thought at any time. Fortunately, this came to an end when Firo learned about the abuse Szilard put her through, and killed him shortly afterwards.

Appearance
Ennis is a young woman of average height with a pale skin complexion. She has red hair that sticks out on both sides of her head and matching red eyes. When working for Szilard, she is always shown wearing a typical black tuxedo with a white collar shirt underneath. She continues to wear this attire even after being freed by Firo.

Personality
When first created, Ennis was little more than emotionless, until the day she devoured an alchemist pursuing Szilard. As a result of absorbing the alchemist's memories and feelings, she comes to learn what it means to be "human" as well as the concepts of sin and morality, things she previously had never even heard of, let alone have any concept of. Though plagued with guilt over her sins, Ennis continued to serve Szilard due to the fact that he could literally kill her with a thought. She even grows to envy people who complain that there is no meaning in their existence or that they have no purpose, because she is all too acutely aware of her purpose; she is the tool and weapon of a man she can never hope to escape, forever expected to fulfill her orders without thought or hesitation.

Ennis is able to live in such a manner for some time, tolerating her own existence more than anything else. Ever quiet and withdrawn, she speaks only when necessary and savours the moments of silence in-between orders whenever she can. She becomes skilled at suppressing her feelings while in Szilard's presence and while fulfilling his orders, able to set aside all personal thoughts in order to fully focus on one task at a time. This changes after she meets Firo,

One of her main challenges appears to be that of emotional nuance. For some time, she is unable to recognize others' romantic feelings toward her, much less realize whether or not her own feelings are platonic or romantic, and it is for this reason that she initially views her relationship to Firo as sibling in nature. Eventually, however, she grows to realise that her feelings for him are actually romantic and the two get married- fifty years after they first met.
