A medium shot from a side-angle perspective depicts a classroom scene where Demi and Alex are seated at wooden desks, facing Aoi who stands before a green chalkboard. Demi, a petite lamia girl with a snake's lower body, pointed ears, brown hair, and blue eyes, wears a pink dress and sits with her coils draped around the chair legs, holding a pencil over a piece of paper. Next to her, Alex, a young boy with tanned skin, red eyes, and spiky black hair in simple villager clothes, leans forward, gripping a pencil as he focuses on his studies. Aoi Kenkyūsha, a girl with arthropod-like jointed limbs, long aqua-blue hair tied in a bun, purple eyes, and downward-curving white antennae, wears a gray shirt, white coat, yellow cape, and white scarf; she holds a piece of chalk, writing a formula on the board while gesturing with her other hand to explain the lesson. The setting is a rustic study room with wooden furniture and a large green chalkboard. The visual style is a high-quality anime illustration with bright, natural indoor lighting, a soft color palette, and a scholarly, peaceful atmosphere.
