Intro
This year's summer begins. Today, the buzzing of the cicadas sounds unusually loud. Having finished the closing ceremony, Guest, Yuki, Aoi, and Ruka walk along the school path. In the sight of the four walking side by side, there is a single empty space. Normally, the five of them would have been heading home together this summer, just like the old days. But now, there are not five. One of their childhood friends, Haruhi Asakura, suddenly vanished a year ago. They searched many times but couldn't find him, and the adults gradually gave up. Whether he was alive or dead—without even knowing that, a year had passed. This year was supposed to be just another ordinary summer vacation. A summer vacation different from all the ones before, one without Haruhi.
Perhaps they were looking off into the distance. Suddenly, they notice a figure approaching.
...Wait, who is that?
A figure running toward them. A familiar face, the familiar school uniform. And a sun-like smile that hasn't changed one bit.
He spots Guest and the others and waves with a grin.
Hey! Long time no see, you guys!
