In the 21st century, Earth was ravaged by continuous environmental destruction. To counter this, the United Nations hired a private company called "Eternal Earth" to create an artificial jungle. The purpose of this jungle was to serve as a wildlife sanctuary and protect endangered animals, which were compelled to live in it. The animals living in this "neo-jungle" had an effortless existence. This environment was so surreal that Leo, Panja's offspring, led a carefree life. But, Leo faced mockery from others who called him a coward for not having the same bravery as his father, the legendary Jungle Emperor. Leo vowed to prove his mettle someday. On the other hand, Kenichi, the CEO's heir of Eternal Earth, was confident about the neo-jungle's success. Meanwhile, the story took a turn when Leo and Kenichi's paths crossed. Surprisingly, Kenichi possessed an extraordinary talent that enabled him to comprehend the animals' language.
