The Cieln that closes off Phase 2 of Ar nosurge: Ode to an Unborn Star, this Song was created by Undou Quinquem and Sarly Planck in an attempt to solve the problem Zillillium Rimonite caused by switching the power source of Colony Ship Soreil. Soreil has two power modes: one in which it harvests energy from other dimensions using the Ar nosurge Tube, and another in which it converts the life force of the living creatures that have been imprisoned in the Flask Sea into energy.
