蝶 by 工藤静香

"Chō" (蝶（ちょう）, lit. "Butterfly") is a song recorded by Japanese singer Shizuka Kudo for her eleventh studio album, Doing. It was released through Pony Canyon as the album's second and last single on March 21, 1996. The song featured on TV commercials for the Takano Yuri Beauty Clinic. The B-side, "Melody", served as ending theme to the 1996 AX tanpatsu drama Ren'ai Zenya: Ichido Dake. "Chō" is the second in a consecutive trilogy of singles with titles made up of only one character: "Chō" is preceded by "7" and followed by "Yū". It is Kudo's last single to be released in cassette format.
