A mysterious young man who lured the girls to the mansion in which they were killed. Herve witnessed his mother being killed after she fell victim to the family's curse and transformed in a monster. Subsequent to this, his goal has been to help his sister and cousin, the last two female members of his family, avoid a similar fate. Unfortunately, they too manifest similar symptoms, much to his despair.
Herve is somewhat estranged from the rest of his clan as he doesn't agree with their use of resources where Lise is concerned. He feels the efforts to find a cure for their curse would be better spent on helping his sister and cousin. Lise's presence within the clan further aggravates Herve already seething hatred for the Animus (whom he blames for his family's tragic fate).
