Tabi ni Deyou, Horobiyuku Sekai no Hate made  

Our Journey to the End of the Ceasing World, 旅に出よう、滅びゆく世界の果てまで, Hành trình đến tận cùng thế giới

The story revolves around a boy and a girl who travel together through a world that is gradually nearing its end. A mysterious illness has emerged that erases the very existence of everyone who suffers from it. The story does not, however, focus on the tragic aspect of this fairly post-apocalyptic setting, but rather shows the people and events the two travelers come across during their journey.(Source: Baka-Tsuki)
