"Blue Rose" is a song recorded by Japanese singer Shizuka Kudo, from her ninth studio album, Expose.

[3] The single's B-side, "Door", is the ending theme to the TX television series Tsumiki Kuzushi: Hōkai, Soshite....[4] Kudo performed "Blue Rose" on the 45th Kōhaku Uta Gassen, marking her seventh consecutive appearance on the show.

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.

[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.

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.
