BNA

Synopsis

Upon encountering another berserk beastkin, Michiru and Shirou attempt to take it down when a group of drones called Engel Machines appear and capture it. Following the trail to the medical center, they find that the drones were sent by Alan, who claims that the so-called "Nirvasyl Syndrome" is the result of stress caused by several species of beastkin amassing together and is what wiped out Shirou's village. When Alan reveals he intends to prevent this by developing a vaccine to turn beastkin into regular humans, Shirou becomes furious at the idea, going against both Michiru and the police. While Alan tasks Michiru and Nazuna with putting on a concert to calm the beastkin until the vaccine is complete, Barbaray tells Shirou she is planning on dismantling Anima-City to disperse the beastkin to keep them safe. However, when Barbaray goes to visit Minister Shiramizu regarding the matter, he places her under arrest, as it is revealed he is working alongside Alan.
