In this touching anime tale, we follow Escha and Chron, two women with opposite personas akin to the sun and moon. Hailing from the desolate, colorless world of 'Terminal' in a post-apocalyptic future, they journey across dimensions to the present, known as 'Transit.' Immersed in the sights and sounds of this newfound era, the once bleak Terminal metamorphoses into a vibrant realm as they embrace the beauty and melody of their surroundings.
