As a war rages on between a machine-based empire and a magic-focused empire, a witch and a soldier meet and fall in love. Will their romance bring an end to their nations' conflict?

As graduation nears for Kyouko Hori, Izumi Miyamura and friends, they reminisce about their high school memories, cherishing the fleeting yet vibrant moments spent together.
