In Search of the Lost Future

Sou is an ordinary high school student. His biggest worries are his Astronomy Club's project, the zany antics of his fellow club members, and his childhood friend who's suddenly not her usual cheerful self. But then, things take a strange turn...

After Yui's sudden and mysterious appearance, the Astronomy Club gang tries to make her feel welcome as she struggles to figure out what she is doing at Uchihama Academy.

Airi reminisces about how she met Kaori and Sou. The Astronomy Club once again takes on the Judo and Karate Club dispute, with a slightly different outcome. And they also make headway on the case of the school ghost.

Sou enjoys getting to know his new camera. And to give Sou more quality time with it, the Astronomy Club uses the fine weather as an excuse to skip classes to go for a picnic. But things go slightly awry when they miss their bus stop.

The kids yawn through a lecture on quantum theory and Schrödinger's cat. And after classes, the Astronomy Club gets to the bottom of the oddly low-tech school festival project of the Computer Club.

The Astronomy Club members discuss the career paths everyone plans to take after high school. But Sou finds out that Nagisa's path is further complicated by an arranged marriage looming over her head.
