Three years have passed since the bombing of Hiroshima and Gen is now a fourth-grader. Hiroshima is still a ruin, and Gen must scrounge for scrap metal to help keep himself and his remaining family fed, but at least commerce has returned to the land. As his mother gradually grows ill from radiation sickness, Gen and Ryuta befriend a group of orphans led by a tough-nosed older child and including a girl who still bears ugly burn scars from the day of the bomb. An old man suffering from depression is also drawn into the group as they come together to support each other and form a makeshift family. Reality is still harsh, however, as many orphans still die lonely deaths and the grim reminders of what happened linger everywhere. (Source: ANN)

School clubs usually advertise their activities, but the goings-on of the GJ Club are a mystery. Kyouya "Kyoro" Shinomiya recently joined and became the sole male member of the five-person club. Besides Kyoro, there is Mao Amatsuka, the club president who has a tendency to bite Kyoro when she gets mad or bashful; Megumi Amatsuka, Mao's composed younger sister who always makes tea and desserts for the club's members; Shion Sumeragi, a demure chess prodigy; and Kirara Bernstein, a meat lover with a strong feline personality. All four girls have some form of interest in Kyoro. With the girls' idiosyncratic and cute personalities, Kyoro's time in GJ-bu will never be a dull one, for better or for worse.
