She's more worldly and experienced than Kaguya, often giving her advice while secretly enjoying her mistress's romantic struggles. Despite her composed exterior, she yearns for normal teenage experiences and friendship.

Yor Forger Long black hair usually tied in a bun with red eyes and a slender, athletic build.
