Chito and Yuuri are childhood friends and the sole surviving humans navigating the ruins of a vast, multi-layered city in Girls Last Tour. Their relationship is the emotional heart of the series. Chi is thoughtful and reserved, acting as the caretaker and driver, while Yuu is spontaneous and carefree. Their contrasting personalities complement each other perfectly, and fans have long celebrated their bond as one of the most tender and authentic friendships in anime. Many fans also interpret their relationship as having romantic undertones, which has contributed to the series' enduring popularity in the yuri anime community.

The ending of Girls Last Tour is one of the most discussed conclusions in modern slice-of-life anime. In the manga by Tsukumizu, Chito and Yuuri reach the very top of the city, only to find nothing left. Their Kettenkrad breaks down, their supplies run out, and the two are left in total silence at the summit of a dead world. The ending is deliberately ambiguous, neither explicitly showing their deaths nor offering a conventional resolution. Many fans consider it profoundly bittersweet, a quiet acceptance of endings that mirrors the series' overarching themes of impermanence and finding meaning in small moments.

As of 2025, no second season of Girls Last Tour has been officially announced. The 2017 anime adaptation by White Fox covered a significant portion of Tsukumizu's manga, and with the manga now complete, a continuation would likely adapt the remaining story arcs. Fan demand for a second season remains strong, particularly as the series has continued to find new audiences years after its original broadcast. Fans hopeful for more animated content featuring Chito and Yuuri continue to show their support through merchandise, fan art, and community discussions.

Girls Last Tour, known in Japan as Shoujo Shuumatsu Ryokou, resonated deeply with audiences because of its unusual blend of peaceful atmosphere and existential themes. Unlike typical post-apocalyptic stories built around conflict and survival horror, the series focuses on quiet exploration, friendship, and finding joy in small things. The dynamic between Chito and Yuuri struck a chord with fans who appreciated genuinely warm and realistic portrayals of female friendship. The series also gained a strong following in online spaces for its introspective tone, meme-worthy moments (Yuu's antics in particular became fan favourites), and emotional depth that rewards attentive viewers.

The Kettenkrad is the half-track motorcycle that Chito and Yuuri ride throughout their journey in Girls Last Tour. Based on the real-world SdKfz 2 used during World War II, the vehicle serves as their home, transport, and one of their most valued possessions. It carries their supplies, their books, and their sleeping quarters. The Kettenkrad becomes a symbol of the journey itself and of the two characters' resourcefulness and resilience. Its eventual breakdown near the end of the series carries significant emotional weight, marking the final stage of Chi and Yuu's long journey together.
