Lilith is a princess from the royal capital of Kadan in the world of the series. She is fifteen years old, with long pink hair and blue eyes, and is described as headstrong and stubborn, yet curious about the people around her. As a member of the former royal family, she initially interacts with the protagonist, Kenichi Hamada, as part of her duty, but over time she becomes genuinely interested in him, finding him an "interesting man." Her role in the story begins when Kenichi arrives at the royal capital seeking an audience with the king; instead, he is received by Lilith. From that point, she becomes a recurring figure in his life, eventually developing romantic feelings for him. In the latter half of the narrative, Lilith becomes one of Kenichi's partners alongside several other women. Her personality shows growth from a duty-bound princess to someone who acts on her own desires and curiosity. She does not possess any special combat or magical abilities beyond those typical of a royal of that world; her main strength lies in her social position and her evolving emotional connection to the protagonist. Her key relationships include her father the king, her maid Mailen, and eventually Kenichi, as well as the other women who share his affection. Lilith’s development is marked by her transition from a sheltered royal to a more open and affectionate individual, driven by Kenichi’s unusual perspective and modern Earth goods, which fascinate her.
