Touru is the top honours student of the adventuring school. While studying abroad, he came across his childhood friend Nikka. However, he soon discovered that Nikka, who he assumed was human like him, was actually descended from ogres and towered over him in size. In this city of giants, everything seemed to be on a mega scale. As a result, Nikka happened to be 100 cm taller than Touru, and he found himself surrounded by a class full of girls in miniskirts. Though unintentional, his mere presence seemed to make their skirts flutter. In this harem tale, experience the thrill of sword and sorcery in a school setting!
