The producers of the Sailor Moon Crystal anime confirmed on Saturday that original manga creator Naoko Takeuchi personally wrote the lyrics for "Gekkō," the anime's ending theme song. The idol group Momoiro Clover Z performs the song, and its lyrics are officially credited to "Shirobara sumire." However, that name is actually the penname for Takeuchi.

"Gekkō" was composed by Akiko Kosaka, who composed "Moon Revenge," "Sailor Team's Theme" and "Tuxedo Mirage" for the original Sailor Moon. It has been about two decades since Kosaka and Takeuchi collaborated on writing the music and lyrics, respectively, for "Tuxedo Mirage."

The combined single for the anime's opening theme "Moon Pride" and "Gekkō" shipped in two CD versions in Japan on July 30. The "Sailor Moon Edition" features the five guardians on the cover and include a bonus music video Blu-Ray Disc. The Momo-Clo edition (pictured below) contains a cover of "Moon Revenge" performed by Momoiro Clover Z and features them on the CD cover. Both editions include the karaoke versions of their songs.

The Sailor Moon edition retails for 1,851 yen (about US$18), while the Momoiro Clover Z cosplay version retails for 1,234 yen (about $12). The songs also debuted on iTunes Music Stores in 120 countries simultaneously at midnight local time on Wednesday.

Momoiro Clover Z announced they would perform the opening and ending themes for Sailor Moon Crystal in July 2012. "Moon Pride" was composed by Revo (Linked Horizon/Sound Horizon), who composed "Guren no Yumiya" for Attack on Titan.

Sailor Moon Crystal premiered on Niconico, Crunchyroll, Hulu and Neon Alley on July 5.
