Juna Ariyoshi is an ordinary Japanese schoolgirl, who possesses a childlike curiosity and a strong admiration toward nature. One day, while on a trip with her boyfriend, Tokio Oshima, Juna dies from a motorcycle accident. However, she is given a chance to live by an individual named Chris Hawken. He offers her powers that make her the avatar of time; in exchange, she must fight to protect the Earth from evil forces called raaja, which are born out of the toxic pollution human beings have caused. She soon discovers that this is no easy task. While trying to master her newfound powers, she must also seek answers to deep questions about the ways science and technology have taken away humans' primal and instinctive connections with nature. With the help of Chris, his assistant Cindy Klein, and a powerful international organization named SEED, it is up to Juna to overcome her fears and find a way to stop the raaja from destroying everyone and everything she cares for.

Seven Japanese high school students enjoy international renown for their remarkable talents. One day, these friends survive a plane crash only to find themselves in the medieval fantasy world of Freyjagard, where two human races live side by side in a feudal society: the byuma, who have animal features and formidable strength, and the hyuma, who have a small chance of magical aptitude. After being rescued by the byuma Winona and her adopted elven daughter Lyrule, the group pledges to use their advanced skills and knowledge to pay back the people of Elm Village for their hospitality and find a way to return back home. Tsukasa Mikogami, the prime minister of Japan, acts as the leader of these young geniuses and organizes their efforts to intervene in Freyjagard and gather the information and resources necessary for achieving their goals. Believing that there is a connection between their current situation and an ancient legend about seven heroes from another world who defeated an evil dragon, Tsukasa directs the others to learn about the culture around them and search for any clues leading them back to Earth. But he also gives another instruction: to take it nice and easy, lest they ruin this world by giving it their all.
