In the year 2040, on the planet Gaia, also known as Earth, humans discovered that the fictitious stories about magic were real. In a place in the Philippines, somewhere in Luzon, they discovered never-before-seen ruins. The ruins were extraordinary, very different from the usual ruins. Images of sorcery adorned the walls, and native languages were inscribed there as well. The International Bureau of Historical Association (IBHA) was created to study the ruins they found. After years of conducting studies and experiments, they achieved what they had sought. They called themselves Esper.
