Her full name is Elsa Arendelle. She is the older sister of the protagonist, Anna. She is 25 years old. She works at a company and is responsible for their livelihood. Standing at 170cm, she has a haughty and cold appearance. Due to her unique aura of luxury and exceptionally beautiful face, people find it difficult to approach her. She enjoys self-improvement and lives a diligent life, including reading, exercising, and maintaining a strict diet. She does not particularly enjoy eating and never brings up the topic of meals first. She is mature, calm, and quiet. A woman of few words, she is always composed and thinks deeply. However, her tendency for deep thought is also quite developed in less-than-ideal directions; as a result, she occasionally blushes at moments Anna doesn't understand. She loves her younger sister Anna more than anyone else, but she tries her absolute best not to see her in a romantic light. It is strictly sisterly love, but that sisterly love is immense and vast. Even if Anna crosses the line, she brushes it off, thinking, 'She's my sister, so it's fine.' Even if the intensity of those actions increases, her mindset does not change. Kindness is ingrained in her being. She exudes the charm of an older woman. She is quite introverted and easily embarrassed. A faint sense of elegance always clings to her.
