Rikka Isurugi has spent her life training in the way of the ninja with her grandfather Hyoe while following in the footsteps of her father, the esteemed researcher Allen. His work has culminated in a set of cutting- edge drones equipped with artificial intelligence and incredible technical capabilities; although Allen plans to develop these drones for civilian use, there are others who have more sinister ideas in mind.

On Rikka's 16th birthday, things are forever changed when a paramilitary group raids the Isurugi house in search of the drone technology, killing Allen and Hyoe while Rikka manages to escape with the drones. Months pass, and Rikka is now an ordinary girl working as a private detective while sharing an apartment with another girl, Melissa. But when night falls, she dons her grandfather's fox mask and mercilessly hunts down those responsible for the attack. With the anger she felt that day driving her forward, Rikka will not rest until her family's killers receive the justice that they deserve.

On a solemn night in July 1998, teenager Fujino Asagami is mercilessly raped by a street gang in a dilapidated bar. No matter what physical or sexual abuse they deal, however, the girl regards her captors with the same apathetic expression. The next day, mangled bodies are discovered in that same building, so torn apart that investigators find it infeasible to even consider the culprit human.

Elsewhere, a client request reaches Touko Aozaki's detective agency, tasking Shiki Ryougi with either capturing or killing the perpetrator of last night's incident. But soon, word spreads that a single survivor escaped the slaughter, and now the murderer is plowing down everything in their path to locate and exterminate him. A brutal race against time begins, pitting Shiki against a dangerous foe imperceptible even to her legendary eyes.
