Thirty-two-year-old narrator Kensuke Yazaki takes a nostalgic look back at the year 1969, when he was an ambitious and enthusiastic seventeen-year-old, living in Sasebo, in western Kyushu, where he gets into antics with his equally ambitious and enthusiastic best friends, Iwase and Adama. Their priorities are girls, cinema, music, literature, pop culture, organising a school festival to be called "The Morning Erection Festival", besting teachers and enemies, and finding a way to change the world somehow.
