The people of the Omega Empire suffer under the oppressive rule of Emperor Duke.
Egregious violence, and possible death, awaits those that defied the heavy taxes…
Everyone lives in fear of the empire.

However, a brave few have risen up to destroy the Empire.
The resistance movement Ψ, headed by Edgar.
On the surface, they work as jack-of-all-trades, helping citizens in need.
However, below the surface, the organization’s main activity is assassinating Imperial officials and criminals who bring suffering upon the people in the name of “purging” them.

One of the members of Ψ is a beautiful, dark-haired woman who you wouldn’t suspect is an assassin.
As a child, she was rescued by Captain Edgar from being sold into slavery by slave traders.
She was then trained by him in various assassination techniques and magic to survive.

With her beloved sword Oborozuki in hand, which she received from Edgar, Hazuki is ready to face the empire once again.
