No discussion of this trope is complete without mentioning the cicada. In anime, the incessant droning of cicadas is the soundtrack of summer. Culturally, the cicada is a symbol of evanescence—living underground for years only to emerge for a brief, noisy life in the sun.
For a protagonist crossing the threshold into adulthood, this symbolism is potent. It teaches them that the endless summers of childhood eventually end. The narrative arc of Shounen ga Otona ni Natta Natsu is almost always one of nostalgia. The story is usually told in retrospect, implying that while the boy has gained maturity, he has lost the innocence and the infinite possibility that defined his youth.
