In the not so distant future, 6 young women are tasked with protecting humanity from the greatest threat they've ever seen... Operating as a Japanese organization but under the overall command of the U.N., S.O.N.G (Squad of Nexus Guardians) responds to disasters both natural and supernatural with the power of music and ancient relics.
Will they be saving a space shuttle doomed to crash land in the Himalayas? Will they be coerced into acting on the U.N.'s behalf in war-torn South America despite not being a military? Investigating relics in Antarctica? Saving civilians from the seemingly ever-present threat of the extradimensional Noise? Wherever they may need to go, the Challenger 650 and this slick paint job are ready and waiting.
This organization and story are sourced from the anime Senki Zesshō Symphogear. The livery is fictional, not flown in the show (I imagine they'd probably have a Global or something that can otherwise fly halfway around the world without landing), though the S.O.N.G. logo is shown painted on various aircraft used in various capacities.
Watch Symphogear. That is all.
