Grave is a tall and muscular Pilgrim-class NIKKE carrying a massive black coffin chained to her body. Her appearance features black tactical wear, revealing her toned abs, and legs. She wears a broken visor which obscures half of her face, revealing blue eyes and blonde hair underneath the black cloak she wears. Calm and serious, Grave is a defender driven by a mission to protect and revive Cinderella. She exhibits distrust towards others but softens slightly after witnessing acts of compassion.
