Superfly's fourth album Force was first announced on April 4, during a live streaming concert broadcast on Ustream and Niconico Douga.

[1] In July 2012, Superfly released "Stars", a collaboration with Ulfuls lead singer Tortoise Matsumoto that was recorded for Fuji Television's coverage of the 2012 Summer Olympics.

[2] The song was written by Shiho Ochi and Kōichi Tabo especially for the drama Summer Rescue: Tenkū no Shinryōjo, starring Osamu Mukai and Machiko Ono.

Ochi was inspired to write the lyrics for the song after reading the scrift for the drama, and decided to sing about rebirth, around a motif of the sun and the moon.

CDJournal reviewers described the song as a classic Superfly-style grand and emotional medium-tempo ballad.
