Ep 6. Fox Waltz

In episode 6 of BNA season 1 titled "Fox Waltz," the world of Anima City is in chaos. Aya is still trying to track down Shirou who seems to be masterminding the destruction of their society. Michiru is worried about her safety but can't seem to keep her mind off of Nazuna's actions. Meanwhile, Shirou has enlisted the help of a fox named Tiago to take Michiru hostage in order to lure Aya into a trap.

As the episode begins, Michiru is surrounded by a group of delinquent citizens of Anima City who are unhappy with the current state of the world. They accuse her of betraying their kind and not caring about their struggle. Michiru realizes that Nazuna has been spreading lies about her, which have caused the citizens to turn against her. In the midst of the chaos, Michiru sees Shirou and Tiago watching from a distance.

Aya is on the hunt for Shirou and receives a tip that he is hiding out in a nearby apartment building. When she arrives, she discovers that the information was a trap and she is ambushed by Tiago. Tiago uses his powers to temporarily cripple Aya's senses and takes her captive. Shirou reveals to Aya that he plans on using her as a bargaining chip to force Michiru to join his side.

Meanwhile, Michiru is forced to confront Nazuna about the lies she has been spreading. Nazuna reveals that she was jealous of Michiru's newfound popularity and wants to take her place as the leader of Anima City. As they argue, Shirou's henchmen break in and kidnap Michiru.

With both Michiru and Aya captured, Shirou has control over both of their fates. However, his plans are thrown into disarray when Michiru refuses to cooperate and even manages to escape her captors. She begins to work with Aya to figure out a way to take down Shirou and put an end to his dangerous plans.

The episode ends with Michiru and Aya successfully infiltrating Shirou's hideout with the help of some unexpected allies. They discover that Shirou's ultimate plan is far more sinister than they could have ever imagined. The stakes are higher than ever as BNA ramps up the tension and sets the stage for an explosive season finale.
