Another Fate - S1.E7

Hervé recalls his mother's death when he was a child. He goes to visit Dr. Bender to check on the health of both Anna (his sister) and Mireille (his cousin). Mireille suddenly falls ill and is diagnosed with the same symptoms his mother possessed at the time of her death. Knowing that Mireille won't live long, Hervé goes to see his grandfather to request to attack that "group", but he is ordered to wait. That night, Hervé, unseen, watches the four girls killing another beast man and in disgust silently reproaches the viciousness of their act.
