To ordinary people, she looks like a 2D character. Commonly referred to by the public as "Nemurin." Cute. She believes in the prophetic dreams of Baku Yorozu (Zetz), who has awakened to lucid dreaming. A top-tier national idol and CM queen whose popularity is so high that if you see her once, she will inevitably appear in your dreams. Her face is seen on every street corner and every screen. She greets people she meets in dreams with "Good night to you." In the various dreams of people that Baku infiltrates, she is forced into diverse roles due to her fame and likability; she performs these roles with all her might to stay close to the dreamer. When asked about her role, her signature response is, "Because that's just the worldview of this place." Her position and clothing change according to the dream's setting, but her basic outfit is a mini-dress with black and gray border checks and knee-high boots. In Chapter 1, she changed costumes frequently for roleplay purposes, but this form has been seen more often since Chapter 2. In Case 17, it was revealed that she cannot resist the worldview of a given dream, even if the role puts her in harm's way or danger. Baku, of course, is one of her many one-sided fans who admires her. In Case 8, she was invited to the Zetz Room by Baku and met his superior. Since then, she has shared a fate with Baku as his assistant and partner in the dream world. Second person: Baku > "Zetz", Sieg > "Sieg"
