花とゆめプラネット増刊 [Hana to Yume Planet]

A special-edition spin-off of Hana to Yume, this magazine ran 27 issues from 1989 to 1997 under Hakusensha, offering a curated platform for the publisher's shōjo manga stars to experiment with shorter serials, one-shots, and side stories. Its limited run made each issue a focused showcase for the distinctive romantic and fantastical storytelling that defined the era.
