Renee Brinvilliers ルネ・パルメデス・ブランヴィリエ
An older generation immortal. In the 1700's she worked as an alchemy teacher in Lotto Valentino. In the 1930's she is a scientist working for Nebula and cares little for anything unrelated to her experiments. Though she seems very innocent and air-headed, in truth she is quite ruthless and cruel.
