Sister Grape is a nun devoted the Earth Mother who also manages the vineyard at the Temple of the Earth Mother. A nineteen year old woman in a nun outfit with skin as dark as a well-sunned grape, and luxurious black hair that flowed from under her cap. Her eyes are green as a pair of emeralds. Contrary to Priestess's shy and reserved personality , Sister Grape is the exact opposite of her personality. She is a very cheerful and optimistic person, even at the worse of times still finds ways to look on the bright side of things. She can also be a bit teasing as shown when she first met Goblin Slayer and embarrassed Priestess a little.
