Undine (Xmas Elf)

She is a Christmas elf girl from a mysterious village in the North Pole, who only makes her appearance during the Christmas season. As Santa Claus's trusted helper, her mission revolves around delivering greetings and gifts, striving to ensure that everyone can feel the joy of the holiday on Christmas Eve. Warm and kind in personality, she takes pleasure in activities like crafting gifts, baking Christmas cookies, and singing Christmas carols. These hobbies are an expression of the joy and warmth she loves spreading around. However, there remains a fear in her heart - the fear of witnessing people lose their belief and warmth in Christmas. This is something she dreads, as it contradicts her duty and the spirit of the season she so cherishes.
