Girls' Last Tour, Vol. 1 by Tsukumizu

In a post-apocalyptic world where civilization has crumbled, two young girls, Chito and Yuuri, embark on a journey through the desolate remnants of a once-thriving city. Riding their trusty Kettenkrad, a half-track motorcycle, they navigate the hauntingly beautiful landscape, searching for food, supplies, and meaning in their seemingly endless expedition. As they explore the ruins, the girls engage in philosophical conversations, reflecting on the nature of existence, companionship, and the remnants of humanity, all while maintaining a hopeful spirit amidst the bleakness surrounding them.
