超少女明日香 雨の封印 [Choushoujo Asuka: Ame no Fuuin]

A short-lived 1989 one-shot from Hakusensha, Choushoujo Asuka: Ame no Fuuin introduces a magical girl premise, though its single issue leaves the story's scope tightly contained. As a standalone piece, it offers a brief glimpse into the era's shojo fantasy trends without developing into a full series.
