The Flame of Sloth, Acedia
She is one of the Seven Black Flames created by the Witch of Darkness. True to her title, Acedia was notoriously lazy.
Whether this was a deliberate "trait" woven into her programming or simply an innate aspect of her personality remained a mystery.
Regardless, she spent most of her days dozing off in various corners of the mansion. Her inactivity was a constant source of frustration for her sisters, who could only sigh at her perpetual idleness.
For Acedia, there was no greater ambition than the bliss of uninterrupted sleep.
