Kagami Omi (Patreon)

[Sometimes we just steal character design aspects we enjoy.]
Omi is the leader of a mercenary band in the East. Happily utilizing the political unrest for monetary gain, she's a bit of a psycho in actual combat.
People often call her the "Hornless Oni" despite not being an Oni at all.
Edit: Touched up slightly, backshot added, and some greyscale.
