The start of summer: Aiuchi Shuuta, a second year at Hokumakidai Academy, is the smartest student in his grade. However, he loses this title for the first time. A girl, Arimura Romi, climbed her way to the top, while continuing to publish cutting-edge research papers online. She's a very mysterious girl: the textbook definition of an enigma. And thus, Shuuta seeks Romi's help on a certain matter. "Aiuchi Shuuta" and "Arimura Romi" It all started from the meeting of these two geniuses-- a distant summer adventure begins.
