This Hymmn is the Song that Kanon crafted along with Cosal for the day of the same name (yal fii-ne noh-iar;), which the Sharls yearn for as the time in which the true paradise will be born, which could be equated to the events that are known in Earth by the names of Judgment Day and Apocalypse. So while the title translates to "Planet of Protective Souls" from Emotional Song Pact, its proper meaning is "may the Demon Hearts lodged within all humans receive purification, and may a new era of light be upon us". It also serves as the subtitle for the first Phase of Ar nosurge: Ode to an Unborn Star's story, though the Phase splash screen gives it the moniker of Song that Protects the Planet 星を護る詩, hoshi wo mamoru uta?).
