Kana Ozawa is a Japanese manga artist from Kanagawa Prefecture. Her professional career is defined by a single major work, the manga series Blue Thermal, which she both authored and illustrated. The series, whose full Japanese title is Blue Thermal: Aonagi Daigaku Taiikukai Kōkūbu, was published in five volumes. The National Diet Library of Japan holds records for Ozawa as a manga artist, with its initial catalog entry for her work dating from September 2015.

Blue Thermal is notable as an original creation drawn from Ozawa's personal history, as she was a member of an aviation club during her own student days. The story follows Tamaki Tsuru, a university freshman and former volleyball player whose accidental damage to a glider forces her to work with the university's aviation club, where she develops a passion for the sport of gliding. The narrative incorporates elements of personal growth, rivalry, and romance, including Tamaki's complicated relationship with her half-sister, who is a champion glider pilot from a rival university.

The manga serves as the source material for a 2022 anime film adaptation, also titled Blue Thermal. The film was produced by Telecom Animation Film, directed by Masaki Tachibana, and released in Japan on March 4, 2022. Kana Ozawa is credited with the original story for the film, and she also contributed to the screenplay alongside Masaki Tachibana and Natsuko Takahashi. The film adaptation expanded the reach of her original manga, bringing her story to audiences beyond the print medium. No other manga or anime works by Kana Ozawa are documented in available records.
