The cuckoo does not chirp, what is the help?
Oda Nobunaga: "Make it sound".
Toyotomi Hideyoshi: "Tempt him".
Tokugawa Ieyasu: "Waiting for it"
Oda Nobunaga was the first hegemon of Japan's Sengoku period, Toyotomi Hideyoshi completed the unification of Japan, and Tokugawa Ieyasu established the Edo shogunate that prospered for the next 300 years, ending Japan's Sengoku period once and for all. The three are known as the Three Masters of the Warring States. And on the card map of Yu-Gi-Oh's [Wanting to Smell Its Cuckoo], you can see the silhouettes of three people, all of whom seem to be looking at this shivering cuckoo.
The three masters of the Warring States completed the great cause of dominating the world, so the descendants compiled this fable of "the cuckoo does not sing" based on the deeds of the three. In this fable, the great cause of unifying the world is embodied in a small cuckoo. How to make the cuckoo chirp means what means to unify the world.
As the first king to rectify the troubled times of the Warring States, Oda Nobunaga's answer was "make it sound". This answer means that if the world is not unified, then let it be unified. It is in line with his great achievements in conquering the daimyo of various countries by force and providing the basis for the reunification of Japan.
Oda Nobunaga's plan to conquer Japan ended with the Honnoji Revolution. After Nobunaga was killed by Mitsuhide Senshi, Toyotomi Hideyoshi defeated Mitsuhide Senshi and completed the unification of Japan in the true sense. Before that, Hideyoshi, as Nobunaga's subordinate, tried his best to assist Kuramae Mae. Treating the cuckoo who does not sing, seducing its song is the embodiment of Toyotomi Hideyoshi's good use of power schemes.
Tokugawa Ieyasu, as the terminator of the Warring States chaos, had been holding back before that. He successively attached himself to Oda Nobunaga and Toyotomi Hideyoshi, slowly accumulated power and connections, and after their deaths one after another, it was logical to become the largest power in Japan. "The cuckoo does not crow, wait for its sound" is also the best embodiment of Tokugawa Ieyasu's style.
