Grave

Grave is the mother of ravens and a stray otherworlder. She struck a deal with Tempest- the protection of her raven children in return for protecting the nation as a night guard. Her eldest son was given a name by Rimuru and became his subordinate.

Appearance
Grave has pale gray skin with a curvy figure, sharp fangs, and clawed hands. Black iridescent feathers sprout from her body, most prominently from her neck and hips, and her arms fade to black from the shoulder. She has flat black eyes which appear iridescent at night and fluffy iridescent black hair which blends into the feathers around her neck, two longer strands in front reaching down to her waist.

When taking a more human form, her feathers smooth out to appear as clothing and her hands lose their claws. She has pupiless purple-blue eyes with black sclera and her hair becomes more defined against her feathers.

Characteristics
Yama: Lord of Death: Grave's Ultimate Skill.

Trivia
