Lilith

Lilith stands as the legendary founding matriarch of the Dark Clan, a demon lineage of immense antiquity, and the most distant known ancestor of protagonist Yoshida Yuko. Thousands of years ago, she was sealed away during a great conflict with the Clan of Light, her soul left to slumber within a golden ancestral statue—one that the Yoshida household had unknowingly repurposed as a humble doorstop. Now communicating through the realm of dreams, she serves as Yuko's enigmatic mentor, guiding her descendant on the path to reviving demonkind. Though she carries herself with regal arrogance and a love of pranks, her own clumsiness frequently undermines her dignity, making her an essential source of both comic relief and heartfelt support throughout the story.
