When a sickly young girl suddenly becomes obsessed with inventing new things, her family and friends are all puzzled. "What has gotten into Myne?" they wondered, never dreaming that the answer is not a "What" but a "Who": Urano Motosu, a book-loving apprentice librarian who died in an earthquake in Tokyo who somehow found herself in Myne's body! And since Myne's world is still in a medieval stage, where books can only be owned by the elite, the new Myne intends to do everything she can to bring her beloved books to the masses in the time she has left.

In this world, Sensha-do (戦車道), the art of tank-combat, is a traditional Japanese martial art for girls. Miho, a girl who just transferred into the Ōrai Girls' Academy in Ibaraki Prefecture, has been ordered by the academy's student council chairperson to join the school team and compete in the national Sensha-do championships.

After an eventful winter break, Kyoutarou Ichikawa and Anna Yamada reunite with a stronger bond. They continue to grow in their own ways, with Yamada taking on more challenging photoshoots and Ichikawa maturing both physically and emotionally as he tackles his affections for Yamada. However, spending time together outside of school allows for their relationship to deepen, and it becomes increasingly difficult to deny their budding romantic feelings.

Grappling with these unexpected and new emotions, Ichikawa and Yamada realize that, with the passage of time, their relationship is bound to change—and they must ultimately decide whether they wish to remain close friends or finally become a couple.

At the same guild, a priestess who's just become a new adventurer has formed her first party... and the man who ends up rescuing that party when they get into trouble is none other than the Goblin Slayer.
