Install the Darling in the FranXX wallpaper HD new label theme and enjoy the HD background of the mobile fortress city “plantation”. Have you seen Darling in the FranXX at least a hundred times? Enjoy more, 02, raspberry and more. A distant future. Human beings have built a mobile “city plantation” in the fortified land and sang civilization. The driver's living facility “Mistletoe” built in that area is commonly known as “bird cage”. The children live there. Nothing is known about the outside world. Nothing is known about the free sky. The mission they were told was only fighting. The enemy is a huge living body that is covered by mystery. In order to fight against enemies that have not yet been seen, the children take the robot called "Franks". They firmly believe that riding in is a proof of their existence.
