is the third single of J-pop duo FictionJunction Yuuka. It was released on September 22, 2004.
This single includes an insert song of the anime Gundam SEED, composed by Yuki Kajiura. There are two other versions of the song on the single (piano and acoustic), along with its karaoke version. Its catalog number is VICL-35646. Coincidentally, the insert song of Mobile Suit Gundam SEED Destiny (Gundam SEEDs sequel), "Honoh no Tobira", was released exactly one year after this single.
Originally, this song was released on "Suit CD vol.4 Miguel Ayman x Nicol Amarfi", an EP from Gundam SEED, under the name "FictionJunction featuring Yuuka". Due to the song's popularity and the fact that September 2004 was Gundam SEEDs one-year anniversary, it was later released as a single obtaining the twelfth place on the Oricon charts, which later rose to the tenth. The song has been FictionJunction YUUKA's best-selling single.
