Elluka and Gumillia progress East on their quest to find the Twin Blades of Levianta. After they come upon a great wall, the two are stopped by the wall's watchman, who tells them to leave, explaining he had an order from the king to only let their country’s people through.
Leaving the wall, the women paint their hair dark and approach the watchman again; shaking his head, the watchman states that their country’s people didn’t have such pale skin. The women leave and cover their skin with mud; approaching again, the man then tells them the people of their country didn’t have eyes such a ghastly color.
The watchman then implores the two not to think badly of them, stating he and the wall are necessary to protect their great country. Losing her temper, Elluka summons a gust of wind that blows him away and the two finally pass; on the other side, they see nothing, and wonder what the watchman had been guarding. They proceed East on their journey, only to suddenly come upon a vast sea. At the end of the PV, their ship can be seen sailing toward the distant island nation on the horizon.
The song uses GUMI'sVOCALOID2 voicebank. Piano, drums, flute, bass guitar, and accordion are used for instrumentals. The song opens with an instrumental melody, preceding the first verse starting at 0.24. A chorus-like part is sung, then the verse ends at 0.47 and shifts into a brief instrumental break.
This pattern is used throughout the first half of the song, with the beginning of the verse starting at times 00:55, 01:25, and 01:56, chorus-like verses 1:10, 1:41, and 2:12 at and the entire verse ending at 1:17, 1:49, and 2:19. At 2:29, a bridge begins, and lasts until 3:02, when the song shifts back into its original melody. The original pattern of the song continues, with the verse beginning at 3:06, the chorus-like verse at 3:21, and the end of the verse at 3:26. The song briefly trails off for less than a second, then snaps back. The verse begins at 3:46, and ends at 4:00. Afterwards, the opening instrumental plays until the song's end.
Prior to the song's creation, mothy had wanted a song that portrayed both Elluka and Gumillia together rather than just Elluka alone, then decided to have it be sung from the apprentice's perspective.
In a similar vein, mothy had wanted a song that portrayed immigration and was inspired by the video game Papers, Please, particularly the frustrating experience of immigrants having to be turned away because their papers weren't in order.
While creating the song, mothy wanted its sound to have the essence of socialism, including Russian folk song phrases and other tunes from different socialist countries.
Although important to the setting, mothy admitted Chartette and the Twin Blades of Levianta weren't actually relevant to the song's plot, though he enjoyed making the little side story all the same.
