Fictionjunction
FictionJunction is a singing group from Tokyo, Japan, that solely performs songs written by Japanese composer Yuki Kajiura (梶浦由記). The term "FictionJunction" alone refers to this group; solo works between Kajiura and a vocalist are referenced by adding the singer's name after "FictionJunction".
Although both perform under the FJ title and are collaborations with Kajiura, they are separate projects. FictionJunction songs have been featured in anime series such as Gundam Seed, Ookami Kakushi, and most recently Sacred Seven.
