Thunder 3 follows three inseparable childhood friends, Pyontaro, Tsubame, and Hiroshi, known as the 'Small 3.' But their ordinary lives are shattered when Pyontaro's cheerful younger sister, Futaba, suddenly disappears. This urges the trio, determined to bring her home, to set out on a desperate search that quickly grows into an extraordinary adventure.
