While Barbaray escapes from her captivity and heads back to Anima-City with Pinga’s help, Marie informs Shirou that Nazuna is planned to reveal that she is a human, which Nazuna is told is supposed to calm the beastkin. As the concert gets underway, Shirou informs Michiru thats Nazuna’s confession will actually trigger the Nirvasyl Syndrome. Michiru convinces Nazuna not to make the confession, only for Cliff to expose her himself which, along with weapons sent in by Alan, sets off the syndrome in several beastkin. Shocked by this, Shirou also succumbs to the syndrome and attacks Michiru.
