The novel begins with an introduction to the situation of the current world.
In the year 2015, Nogi Wakaba is an socially awkward girl who is currently in an evacuation center with her classmates. After a misunderstood and embarrassing moment, Uesato Hinata takes a picture of her and adds it to her 'treasured Nogi-chan collection'. Frantic, Wakaba pleads for her to delete it and Hinata leads her to a group of girls she was staring at earlier.
With a little guidance, Wakaba settles in with the group, and later thanks Hinata for helping her as the friends walk outside. As payback, Hinata asks if she can model for cosplay pictures; much to the former's chagrin.
An earthquake suddenly hits, and the two girls try stay safe-when Hinata has a vision of something 'really scary'. Vertex suddenly appear from out of nowhere, and attack the evacuation center where everyone else is. Through the chaos, Wakaba discovers-to her horror-that her new friends didn't survive. Angry, she dives towards the Vertex and battles them with a wooden stick. It easily breaks, and Wakaba is forced into a corner.
Suddenly Hinata appears, telling her 'it should be there'. In a broken alter, Wakaba finds an old katana that suddenly turns new again once she grabs hold. Not having a chance, Wakaba takes down a few Vertex and the rest regroup. She and the survivors make a beeline for The Great Seto Bridge, Vertex on their tail.
Three years later, Wakaba has assembled a team of 'Heroes', each with their own magical weapon they bring to battle. Aided by Hinata's visions and knowledge, the girls lead somewhat ordinary but adventurous lives within Marugame Castle-now converted into a school for heroes.
Wakaba regularly makes contact with Shiratori Utano-the sole hero protecting the Nagano district a lake over. The two have an Udon/Soba competition due to a debate over the two. Wakaba notices the line has become more unstable lately, and grows worried for her friend.
After Doi Tamako, a member of the team, tries to 'show off' Hinata's bust, Koori Chikage walks by in the background, slightly annoyed. Takashima Yuna then arrives, which makes Chikage delighted. The team has lunch, during which Tamako speaks out to Wakaba, then apologizes solemnly. Wakaba realizes Tamako is scared of the fight that is coming. Yuna then comments the food was delicious, not paying attention to the previous conversation.
Wakaba is still conversing with Utano-solemnly, though. When Utano suddenly starts breaking up, Wakaba gets worried, asking her if everything is alright. It is revealed Utano is hurt and an army of Vertex is approaching, 100-1. Utano asks her to keep fighting, as the rest is in her hands. The line falls dead, and Wakaba realizes with utter terror that Nagano has fallen.
Wakaba oversees the Forestization, and vows to protect the world in Utano's place. The Vertex have arrived.
