"Promise" was originally composed by
Inoran and was first played by Luna Sea at the
World Memorial Hall on December 30, 2010 as part of their
20th Anniversary World Tour Reboot -to the New Moon- reunion tour. At the time it was reported to be titled "Promised Night". Originally there were no plans to release the song, however after the
2011 Tōhoku earthquake and tsunami the band decided the best way they could help contribute to the recovery was to
"generate support through music because music is the reason of our presence and our lifetime mission.", and donated all proceeds to the
Japanese Red Cross and
American Red Cross for
earthquake relief and recovery. ==Track listing==
