is a song recorded by Japanese singer Misia for her eleventh studio album New Morning. It was released as the album's second single by Ariola Japan on February 5, 2014. The title track was released digitally and serviced to radio two weeks prior, on January 22, 2014. It is the theme song to the TBS drama series S Saigo no Keikan, starring Osamu Mukai and Gō Ayano. Misia first performed "Boku wa Pegasus Kimi wa Polaris" on January 18, 2014 at Nippon Budokan during the Hoshizora no Live VII concert tour. Background and release "Boku wa Pegasus Kimi wa Polaris" is Misia's first single in five months, since "Shiawase o Forever" (2013). The first pressing of the single included a live take of "Koi wa Owaranai Zutto" recorded at the Kawaguchiko Stellar Theater on August 26, 2012 as a bonus track. The CD single features two B-sides, including "Kimi no Taiyō ni Narō, which was used in television commercials for Seiko's Lukia watches, starring Emi Takei. The second, "Jewelry", is the last song recorded by drummer and longtime Misia collaborator Jun Aoyama before his death. The single was thus dedicated to the late Aoyama. Composition Musically, "Boku wa Pegasus Kimi wa Polaris" is a piano-and-strings-driven pop song written in the key of A-flat major. Misia's vocals span from F3 to E5. In an interview with Natalie, Misia explains that, when she received the offer to create a song S Saigo no Keikan, she received the directive to make it a "ballad that's also love song". Later, the TV producers changed their demands to "a ballad that's also a love song that's also about friendship". Misia and her producer ended up selecting a demo by Hiroaki Yokoyama. With a common time tempo of 84 beats per minute, the song is not quite a ballad but was slow enough to respect the producers' vision. Once she got approval, Misia then began writing the lyrics for the song. Misia alternated between reading the script over and writing phrases until she completed the lyrics. Misia told Natalie that for the past year, she had been playing with the idea of writing lyrics that could also serve as an allegory. The lyrics to the song depict an epic love story, using metaphorical references to the Pegasus constellation and the guiding star Polaris.
