Synopsis
Rikka Isurugi has spent years training in ninja arts under her grandfather Hyoe, while also carrying forward the work of her father Allen, a brilliant scientist who created highly advanced AI-driven drones. Allen intended these drones to serve peaceful purposes, but others want to exploit them for malicious ends. On her sixteenth birthday, a paramilitary unit storms the Isurugi home, targeting the drone technology, and brutally murders both Allen and Hyoe. Rikka manages to escape with the drones intact. Now living an ordinary life as a private investigator and sharing an apartment with a friend named Melissa, Rikka dons her grandfather's fox mask at night and pursues those responsible for the attack with relentless fury. Driven by the rage that ignited on that tragic day, she vows to bring her family's murderers to justice.
