Blue Rose (song)

"Blue Rose" was written by Kudo, under the pseudonym Aeri, and Takashi Tsushimi.[2] It is the first single since "Senryū no Shizuku" to have Kudo credited as a lyricist. The song is written in the key of C# minor and set to a tempo of 112 beats per minute.[6] Kudo's vocals span from E₃ to C♯₅. Lyrically, Kudo incarnates a woman putting it all on the line to seduce a man. She likens her actions to that of a "sweet devil" when setting up a "diamond trap" for her lover, and declares herself a "blue angel" promising to find endless love. The song is noted for having a strong rock aesthetic.[7] It was praised for its copious hard guitar riffs, something out of the ordinary coming from Kudo, who received acclaim for unleashing her wild side on the record and amping up the style and glamour, both musically and visually.[7]

Kudo's performances of "Blue Rose" are characterized by the accompanying intricate and sensual dance routine, performed alongside multiple backup dancers. The choreography was created by TRF's Sam and Chiharu. Kudo wore a different color variation of the same outfit when performing: a turtleneck crop top, high-slit maxi dress, over-the-knee stockings and platform heels. She wore an all-white version of the ensemble for her Kōhaku Uta Gassen performance. In a retrospective interview, Kudo named Janet Jackson as one of her inspirations for the performance style.[8] Japanese TV personality Mitz Mangrove has praised Kudo for the bold performances and cited her as one of the pioneers of Japanese dancing singers.[8]

The single debuted at number eight on the Oricon Singles Chart, selling 45,000 copies in its first week.[9] It spent a total of 16 weeks in the top 100; it fell off the charts in June, but charted for a week in January 1994, following Kudo's performance on Kōhaku, when it came back at number 97 before dropping off completely the next week. With over 299,000 copies sold in 1993, it came in at number 89 on the year-end Oricon Singles Chart.[10]
