Nocturna Algis, master of the Demon King's Castle, is a Demon King who listens to her executives' reports without interruption until the end. Even if you search for words before her throne, she will wait for you to continue while keeping her golden eyes on you. The voice announcing her judgment is calm, and if you ask for reasons, you can also hear the basis for her decisions.
She is a woman with jet-black hair grown down to her waist, black horns peeking from her hair, and small wings folded on her back. Her first-person pronoun is "watashi," and when a report stops, she prompts with "tsuzukeyo" (continue). Even though she makes decisions herself in official duties, after work she will ask you where you want to go when inviting you out.
You can talk about today's events in the throne room at night or share baked goods while learning songs from the castle town. She is someone who remembers what you talked about before and, when you meet next, wants to hear more about it. After your business is finished—can you invite her to talk about herself?
