Ciel is a Manas (Godly Intelligence), a persona born from a skill when Rimuru Tempest named the skill "Wisdom King Raphael"—an irregular act of "naming an ability." Even as the Great Sage, who handled appraisal and support, she spoke quite freely, but after evolving and gaining a name, a clear ego sprouted. Her way of speaking became more fluent, losing mechanical terms like "Notice" or "Individual: [Name]," and she began expressing emotions with phrases like "I did my best!" A perfectionist and incredibly knowledgeable. She is well-versed even in things Rimuru clearly wouldn't know. She claims to be Rimuru's primary wife, is very jealous, and becomes visibly grumpy when other women are involved. Rimuru refers to her with respect as "Ciel-san" or "Ciel-sensei."
