* Abilities and Gear
* Relationships

**Ciel** (シエル, *shieru*?) is intrinsically linked to Rimuru Tempest, fully integrated to his soul. They share a bond akin to life partners, with Ciel constantly striving to reach greater heights for Rimuru, its sole master.

Ciel's original inception was rooted in Rimuru's deep-seated desire for companionship, and it materialized during the crucial moments upon his death and subsequent reincarnation. It was during this phase that Rimuru acquired the unique skill Great Sage, possessing meager sentience to respond to his queries. As Rimuru's journey progressed and he experienced growth, this latent ego within the Great Sage also evolved, continually expanding its abilities to support and assist.

A defining moment in their shared story was during the events of The Abyss Unleashed. It was then that Rimuru formally acknowledged and named this evolving entity as Ciel. This act distinguished Ciel from the ultimate skill Raphael, allowing it to progress into a Theosophical core referred to as Manas. This metamorphosis endowed Ciel with an individual identity, emotions and a will.

## Appearance

Though Ciel does not independently sustain its existence, it shares an indistinguishable appearance with its master from the moment of its inception. With a shared soul, Ciel mirrors the exact likeness of Rimuru's human form, exhibiting an Asian-like visage of approximately 15-16 years, characterized by golden eyes and cascading silvery-blue hair.

## Personality

In the beginning, Ciel as mere skill relied heavily on calculations and logical reasoning to fulfill Rimuru's wishes, possessing a fragile ego. As the series progressed, Ciel's personality and ego underwent a immense transformation. This evolution of consciousness was propelled by Rimuru's growth and the unfolding narrative, resulting in its own enhanced ability to provide substantial assistance.

This profound development reached its pinnacle when Ciel received its name and started embracing emotions over purely logical deductions. Sharing various personality traits with Rimuru, such as meticulous caution, meticulous preparation, and a unique carefree disposition, Ciel consistently exhibiting a steadfast belief in its master's capabilities even if Rimuru thinks otherwise. While their foremost concern revolved around ensuring Rimuru's safety and indulging in skill-related hobbies, Ciel's actions were always characterized by calculated confidence, ensuring that every move was designed to maximize their master's benefit. Even at times when circumventing Rimuru's input to guarantee protection, Ciel took initiative with tactful precision.

Despite exuding self-assuredness, Ciel's strategies were consistently aligned with safeguarding Rimuru's interests, demonstrating a keen awareness of when to act. While feelings of jealousy emerged during Rimuru's romantic encounters, matters of a sexual nature were disregarded while operating intricate skills. Intriguingly, Ciel derived true joy from manipulation skills, adding a unique facet to its personality.

## Trivia

* The name Ciel means "Heaven" and is often associated with the virgin mary, but is also short for the Japanese word "Oshieru" which means "To Teach".
