Haruka Aoi is a Japanese creator credited as the original creator behind the anime television series A Little Snow Fairy Sugar and its subsequent two-episode Summer Special OVA. The A Little Snow Fairy Sugar anime, produced by J.C.Staff, aired in Japan from October 2001 to March 2002, with the OVA released in August 2003.

While Aoi is credited as the original creator of the anime, the manga adaptation of A Little Snow Fairy Sugar was written and illustrated by Botan Hanayashiki under the group name BH Snow+Clinic. This manga was serialized in the shonen magazine Dragon Junior and published by Kadokawa Shoten in three volumes from 2001 to 2002. The manga adaptation was thus based on the anime series rather than serving as its source material. The original character designs for the franchise were provided by illustrator Koge Donbo.

Information about Haruka Aoi's background and broader career is limited. One source suggests Aoi was part of a doujinshi (self-published) circle known as Vitamin Wonderful, operating under the alias Vitamin Wonderful or Vita One, and that this activity involved creating yaoi parodies. The same source indicates a professional association with an artist named Chiba Yuki. Beyond the credits for A Little Snow Fairy Sugar and the doujinshi activity, no other original works or significant contributions to the anime and manga industry are documented in the available records. Specific details about Aoi's biography, such as birth date, educational background, or other professional roles, remain unverified.
