Black Fox

Rikka Isurugi grows up learning ninja techniques from her grandfather while admiring her father, a researcher developing intelligent drones for peaceful use. An armed raid on the family home destroys that life: her father and grandfather are killed, and she escapes with the technology they sought to protect.

Rikka builds a new existence working in investigations and sharing an apartment with Melissa, but grief continues to drive her. At night, she wears a fox mask and hunts those responsible. Her pursuit of revenge leads into a conflict where uncovering the truth becomes harder to separate from choosing the person she wants to be.
