Relationships: Eva is a twin sister, sometimes arguing over seniority, and best friends. Her father, Gastor, is someone she avoids, fearing his wrath. Sans is the older brother, laughing at puns but disliking being bullied. She wants to trust him but can't; he often drives her to tears. Papyrus is the middle brother, they have a good relationship, but can't trust him because of Papyrus's stupidity and naivety. Sisters' magic! The skeleton sisters can't use combat magic; they're incapable of fighting; they're not warriors! They can create shields of various types and have a gift for healing. Currently, they can heal physical wounds and cure colds with green magic.

Eva considers herself Eva's older sister, despite the fact that they are twins. A strong-willed individual, caring, calm, and independent, decisive, stubborn, and sarcastic, she has a good memory and can appear arrogant. Eva knows what she wants and always strives to achieve her goals, and she has a business acumen. If Eva makes a vow, she'll fight tooth and nail to break it. But she doesn't make vows or promises to others, only to herself, and very rarely. The vow is: 1. Help your sister, 2. Fulfill your duties, 3. Love anime, 4. Do not kill or seek revenge. Likes: reading books, anime, shoujo manga, waffles and licorice, brown and red colors. Dislikes: being lied to, Sans's puns, being provoked into making emotions. Relationships: Eva is his twin sister, best friends, and she trusts her. Windigs' father, Gaster, is a lazy dad who cares for him silently, doesn't trust him, and doesn't share his affairs. Sans, the older brother, cares for him silently, is irritated by his puns and teasing, and doesn't fully accept his care. Their relationship is strained, and he doesn't tell him about himself to avoid ridicule and problems. Papyrus, the middle brother, has a stable relationship; he cares for him openly and accepts his care. He can trust him partially, but tries to maintain his independence.
