It was released as the fifth single from the album by Victor Entertainment and their subsidiary label Flying Dog on April 27, 2016. The lyrics were written by Yamada Toshiaki and the music was composed and produced by Swedish electronic dance musician Rasmus Faber. Musically, "Ai no Uta (Words of Love)" is an electronic dance song, influenced by four on the floor that features synthesizers and string arrangements in its instrumentation.

Upon its release, it received positive reviews from music critics. Some complimented the composition, noting a departure from her previous J-pop influenced music, and commended the songwriting. Commercially, the song fared better in Japan than her previous releases, peaking at number 47 on the Oricon Singles Chart. An accompanying music video was directed by Nozomi Tanaka, which featured Chisuga in a large aquarium surrounded by bright lights. To promote the single, Chisuga appeared on radio stations throughout Japan including Rajira Sunday and Hiroshi Kamiya's All Night, and was used as the closing theme song for the second season of Japanese anime television series, The Asterisk War.

Background and release
On October 4, 2015, it was confirmed through Anime News Network that Chisuga was to voice over the character Sylvia Lyyneheym for the second season of Japanese anime television series, The Asterisk War. However, Chisuga did not comment about a potential theme song recording for the show. Then in February 2016, Chisuga confirmed that a new song, titled "Ai no Uta (Words of Love)", would serve as the show's ending theme song. "Ai no Uta (Words of Love)" was written by Yamada Toshiaki and produced by Swedish electronic dance musician Rasmus Faber. Musically, it is an electronic dance song, influenced by four on the floor and incorporates "elegant strings" sections, as described by a staff member at CD Journal.

The single was released as the album's fifth single by Flying Dog, a subsidiary label owned by Victor Entertainment, on April 27, 2016. It was released on a CD single in Japan, which included the track, two B-side songs "Lonely Feather" and "Ai no Taiyou", and an a cappella version of "Lonely Feather". It also included the instrumental versions of the first three tracks. The digital EP included the four recordings but omitted the instrumental versions. Through CDJapan.com, pre-ordered versions of the CD single included a large B2-sized poster and a scanned hand-written letter by Chisuga herself, which was then signed.

Reception
Upon its release, it received positive reviews from music critics. A staff member at Amazon.com complimented Faber's production and arrangement, who believed he was able to "expand" Chisuga's sound outside of J-pop. The reviewer also complimented the songwriting and her vocal performance. In a similar review, a CD Journal staff member praised Chisuga's "free" and "vigorous" vocal performance, alongside its "glossy" production. The review concluded with the reviewer calling it a "high degree of completion".

Commercially, the song fared better in Japan than her previous releases. It debuted at number 47 on the Oricon Singles Chart, her highest selling entry and first top 50 single since "Planet Cradle" / "Wandering" in 2013; it sold 1,462 units. Despite falling outside of the top 50 the following week, it lasted eight weeks inside the top 200.
