Shimada Kanon aims to be the strongest tank crew in the Kantou region. With her best friends Mariko Mutsumi, and their World War II-era, Panther V, they form the Nora Middle School Tank Crew. Unfortunately, as they have no sponsor to fund their effort, their dream is still just that. However, a chance to make a name for themselves arrives when delinquents come knocking on their school's door riding T-55s...

The story begins 15 years after the demon king was defeated and the world has become peaceful. Kotone, who graduated from school and became a magician, inquired the kingdom-affiliated RPG Real Estate in order to find a new home. In reality, RPG Real Estate was Kotone's place of employment, and together with Fa, a demi-human, the priest Rufuria, and the soldier Rakira, they help support the searches of new homes for the customers with various circumstances.

After a long and treacherous journey, our Hero finally arrives at the Dark Lady's castle only to find himself being asked for help. The Hero explains how the war that the demons have brought upon the humans have killed thousands and put more in misery. The queen of demons however argues that this war has made the human society band together as one and showed empirical evidence how it has increased population, increased production, boosted economy and improved society overall. Furthermore, she explains to the Hero that ending this war will result in a civil war that will produce more bloodshed than there ever was. The Hero, convinced that the only way to bring peace, relatively speaking, is to join forces with the Dark Lady, agrees to help with her plans!
