[b]Name:[/b] Ennis 
[b]Gender:[/b] Female
[b]Appearance:[/b]

[b]Personality:[/b]
When she was originally created she was entirely without emotion, designed to be an obedient servant. After taking care of a rival alchemist that threatened her master she absorbed his memories, learning the concepts that were the core of humanity to built her own personality off of over time. Ennis is observant and calculating, content to simply be dragged along with a situation rather than initiate it herself but will not hesitate to help someone in need.
[b]Brief History:[/b]
Ennis was created and a homunculus in the service of the alchemist Szilard Quates during the prohibition era in the United States. He gave her immortality, the same as his own and the ability to kill her fellow immortals. She begins to feel guilt over her involvement in the deaths of others. Eventually she betrays him in defense of her friends that had gotten on the wrong side of him.

She slowly falls in love with the man who saves her from Szilard. Years later aboard a cruise ship in the year 2002 they become involved in a hijacking of the ship and it's sister ship where a mercenary group attempt to capture another immortal that was on board. Partly due to their help the situation is concluded and they spend the rest of their vacation in Japan.
[b]Universe of Origin:[/b] Baccano!
[b]Equipment:[/b] None
[b]Abilities:[/b] Ennis possess absolute immortality, enabling her to recover from any illness or injury and prevents her from aging. With this she is also able to kill other immortals of the same type by placing her hand on their head and willing herself to devour them. This also gives her their knowledge and memories. When an immortal is injured in the same location multiple times they become faster at recovering from the damage.

Immortals are bound by a set of rules. They are entirely unable to use false names in the presence of other immortals and are unable to continuously use a fake identity around mortals. They also must always use their true name in writing. 

Aside from her immortality Ennis is an agile and capable fighter, easily a match for any human and knowledgeable thanks to decades of her own experience and the vast amount of knowledge given to her by her former master.
