The Ultimate Skill Core Manas: Ciel (Divine Wisdom Core) [神智核マナス シエル, ShinchikakuM a n a s u Shieru]. An intelligent core, she can be thought of as that sort of thing. Similar to a Spiritual Life Form, she is incapable of materializing by her will alone.

Personality Edit

Her actions are based on calculations not emotions. She acts only to be of use to her master Rimuru Tempest before she is evolved into a Manas (Divine Wisdom Core). After her evolution (by having Rimuru naming her), she became an intelligent core with feelings. She does not like anyone looking down on her master and experienced displeasure when Lucia looks down on Rimuru.

Background Edit

Being but a concept of a unique skill, without having any self-awareness, but for the sake of serving its master, unique skill Great Sage desired to evolve. After about a million failed attempts it integrated the unique skill Shapeshifter. Thus evolved into Wisdom Lord Raphael. The Harvest Festival bestowed upon it such a gift.

In the depths of its emotionless mind, was an ego tucked into a corner. Doubting her own existence, a small glimmer of a thought was subtly born, unbeknownst to Raphael. After realizing the deep trust that Rimuru had in Raphael it lead to the birth of emotion.

Rimuru whimsically gave Ultimate Skill Wisdom King Raphael a blessing in the from of a name resulting in the birth of Ciel: Manas (God’s Wisdom Core) and it separated from Ultimate Skill Wisdom King Raphael and become an independent existence.
