Information
Mugen Kigen is the third single by Japanese singer-songwriter misono for her Rock Singles Project, and her ninth overall single. The two prior singles for the project were Zasetsu Chiten and Juunin Toiro. For this single, misono worked with Onsoku Line (Japanese: 音速ライン / English: onoso9line) and their vocalist and guitarist Yoshiyuki Fujii.

Despite debuting at No. 15 on the Oricon Singles Charts, it became her lowest ranking single in the collection, charting at No. 32 for the weekly ranking. As with both Zasetsu Chiten and Juunin Toiro, Mugen Kigen charted for two consecutive weeks. The single was released as both a standard CD and a CD+DVD combo. The CD contained the title track, the b-side "Last Song" and instrumental for "Mugen Kigen." The DVD carried the music video for "Mugen Kigen", video commentary by misono and the television commercials for the single.

"Mugen Kigen" was composed by Onsoku Line's vocalist and guitarist Yoshiyuki Fujii. The song was performed by Onsoku Line and Tanahashi "UNA" Nobuhito from the soft rock band Every Little Thing. For "Last Song," the music was again composed by Yoshiyuki Fujii and performed by Onsoku Line. misono, however, wrote the lyrics for both tracks.

An alternate version of "Last Song" would later be released on the corresponding album to the single, Sei -say-. She would also release all four songs in the project into one melody, which was also placed on the album.
