A woman who may or may not be Naga the Serpent from the Slayers movies can be spotted briefly in the foreground after the cockroach incident in town. While her head cannot be seen, she is wearing Naga's outfit and she has the same build. Her hair is brown instead of purple though. Either her hair color is an animation error, or it is just someone who looks like Naga. Either way, Amelia notices this woman and seems to recognizes her. Although it is never stated in the series, Naga is Amelia's older sister. Explaining her reaction.
