Upon agreeing to testify against the corrupt Katsuhiko Jinnai for his involvement in bribery during the student council elections, Makoto Mizuhara is relentlessly pursued by the boisterous student council president. In a strange turn of events, Makoto finds himself alone in a world where time has stood still, except for himself. Puzzled and startled, he stumbles upon a basement in the school and discovers an unearthed relic, surrounded by a mysterious glow. As he approaches the relic, a mystical woman emerges from it, proclaiming that she has been eagerly waiting for ten thousand years to encounter him. Although weakened by time, she possesses enough power to transport a bewildered Makoto to an otherworldly realm known as El-Hazard. To his surprise, several others from his school also find themselves in this strange place due to the spell, including Jinnai, Fujisawa, and Nanami Jinnai. Together, they embark on an adventure through this stunning and mystical land, while becoming immersed in the intriguing lives of its residents, and experiencing vast laughter, danger, and even romance.
