Frey (Tensei Shitara Slime Datta Ken)

Frey is careful and cunning. Together with Milim, they easily outwitted Clayman by making him believe he had control over them, and even had him convinced that Carrion was dead, with the goal of unraveling the identities of the ones pulling his strings.

Despite having the title of a Demon Lord, Frey is not arrogant and instead she's shown to be humble, admitting she feels not strong enough to be one of the demon lords and resigned her position becoming Milim's subordinate. She is also kind and friendly, showing a maternal side with Milim and deeply cares for her.
