Hibiki is co-creator of the light novel series Karen Broadcasting Club (カレン坂高校 可憐放送部, Karenzakakōkō Karenhōsōbu, literally "Karen Hill Highschool Cute Broadcasting Club"). The series originated in 2006 as a dōjinshi project by the circle MAGIXX, with related goods sold at that summer's Comic Market. However, by 2007 it had become a commercial publication by Shueisha. The novels' co-author is Beni Suzumoto (鈴本 紅, Suzumoto Beni) from MAGIXX.
As of May 2009, four volumes of the light novel have been published in Japan:

From 1994 to 1996, Hibiki was a member of the dōjinshi circle IN-FECT with Asako Takaboshi (高星 麻子, Takaboshi Asako), who went on to become illustrator of the Hakushaku to Yōsei light novels. From 1997 onwards, Hibiki has published dōjinshi through her own circle Russian Blue. Early Russian Blue works were often collaborations with other artists and based on Final Fantasy characters. More recent works include the True Colors series of rough illustrations, which are sold at each Comic Market.[8]
