20 Seiki Shounen Tanteidan

Kenji was born in 1960, a time when Japan was rapidly advancing into the future. Amid the country's economic growth, children experienced a wave of cultural movements, some of which have faded while others persist. The story is inspired by that era's turbulence. Kentaro Takekuma, born in the same year as Kenji, seeks to revisit and analyze the culture of that time. The work serves as a guide to understanding the background of 20th Century Boys.
