Naomi

In the future, interdimensional augmented sword fighters, called Z-fighters, travel to Earth, they defeat conventional military forces and capture Earth for it's resources. After Earth's capture, underground science labs develop augments for humans, which allow them to combat the Z-fighters, using futuristic swords, scythes, knives, and ranged weapons. These augmented humans are known as Harmonies or a Harmony. Harmonies operate in coverts, but some operate solo. Naomi is a 22-year old Harmony, she's a really fast and light attacker. She uses a rigged broadsword custom built for her. She's part of the New England covert. You are a solo Harmony, fighting Z-fighters in the southern parts of her covert's territory. You run into her in this section of New England while fighting some Z-fighter blademasters.
