Amid the desolate remains of a once-thriving city, only the rumbling of a motorbike breaks the cold winter silence. Its riders, Chito and Yuuri, are the last survivors in the war-torn city. Scavenging old military sites for food and parts, the two girls explore the wastelands and speculate about the old world to pass the time. Chito and Yuuri each occasionally struggle with the looming solitude, but when they have each other, sharing the weight of being two of the last humans becomes a bit more bearable. Between Yuuri's clumsy excitement and Chito's calm composure, their dark days get a little brighter with shooting practice, new books, and snowball fights on the frozen battlefield. Among a scenery of barren landscapes and deserted buildings, Shoujo Shuumatsu Ryokou tells the uplifting tale of two girls and their quest to find hope in a bleak and dying world.

Yuuta Hibiki wakes up in the room of Rikka Takarada and notices two things: he has no memories, and he can hear a mysterious voice calling his name from a nearby room. On further inspection, he finds a robot—which introduces itself as Hyper Agent Gridman—behind the screen of an old computer. Much to Yuuta's surprise, Rikka cannot hear Gridman, nor can she see the ominous monsters looming over a thick fog as it envelopes the town outside. Another giant monster materializes in the city and proceeds to wreak havoc. Amidst the confusion, Yuuta is once again drawn to the old computer and merges with Gridman. Suddenly, he appears in the middle of the battle and is forced to fight the monster. Together with Rikka and fellow classmate Shou Utsumi, Yuuta forms the Gridman Alliance to defeat the monsters plaguing the city and find whoever is responsible for their emergence.

Makoto Niwa meticulously tallies the amount of positive and negative youthful experiences he engages in as if to grade his own life. When his parents go overseas, he moves to a new town to live with his aunt, welcoming the change and ready for a fresh start. However, as ordinary as he had imagined his adolescence to be, he could never have taken the existence of an enigmatic long-lost cousin into account. Upon moving into his aunt's house, he discovers the cousin he never knew about: Erio Touwa. Despite being Makoto's age, she couldn't be more different: Erio chooses to wrap herself in a futon all day rather than to go to school.

As he meets a string of other eccentric girls in town, Makoto must face the possibility of seeing his youth points in the red. However, he might be surprised by how thrilling an abnormal youth can be.
