Aoi Hana

Sweet Blue Flowers, known in Japan as Aoi Hana (青い花?, lit. Blue Flower), is a Japanese yuri manga series written and illustrated by Takako Shimura. It was serialized between November 2004 and July 2013 in Ohta Publishing's Manga Erotics F manga magazine. There have been seven volumes published since December 2005, with an eighth volume yet to be published. The story focuses on Fumi Manjōme, a lesbian high school girl, and her close childhood friend Akira Okudaira, who tries to keep her friends happy through difficult times. When Shimura was writing her manga Dōnika Naru Hibi, she became interested in a story between girls, leading her to create Sweet Blue Flowers. While she felt that the story focus should be on girls for yuri works, Shimura also wanted to introduce some males since she thought it would add an interesting aspect to the series.

An 11-episode anime television series produced by J.C.Staff and directed by Ken'ichi Kasai aired in Japan between July and September 2009 on Fuji TV. An Internet radio show to promote the anime was produced between June and October 2009 on HiBiKi Radio Station hosted by Ai Takabe and Yūko Gibu, who voiced Fumi and Akira in the anime, respectively. The anime has been licensed by The Right Stuf International.
