A story of a brother's devotion-rescuing his sister from a gruesome past and leading her to the ocean of freedom-and a sister's despair, haunted by the indelible bruises on her soul. Beneath the fusion of anime-inspired catchiness and a heavy, loud sound, the song chronicles the tragic end of two souls who realize the limits of salvation and quietly head toward their "final day." A piece of narrative music echoing under the starlight: beautiful, yet cruel.
