In the peaceful little town of Sakuranomori, a group of young friends are about to bid farewell to one of their own. Due to his parents’ business plans, Sana Hidaka has to move away from his quiet childhood home to the boisterous city of Tokyo. Though it pains him, he must say goodbye to his precious friends—the kind-hearted Aoi Oribe, the spunky Wakatsuki twins, Shuri and Shuusuke, and the cheerful and upbeat Nanaka Yatsushiro. But even though he is reluctant to leave them behind, he believes that no matter how far apart they are, they will always cherish the memories of their friendship. Five years later, Sana, now a 16-year-old high school student, returns to his hometown with the hope of restoring his old life. However, he quickly realizes that although his town may not have changed drastically, the friends he left behind are not who they used to be. Unsettling shadows loom over Sakuranomori as his friends hold new secrets and bear burdens that threaten the bonds they once shared.

Phantoms: supernatural entities such as ghosts or youkai that, until recently, were thought to be superstition. However, when a virus that infects the brain spreads throughout society, people's perception of the world changes as the mythical beings are revealed to have been living alongside humanity the entire time. This virus has also affected those of the next generation significantly, allowing them to develop special abilities that they can use to fight against dangerous phantoms. Haruhiko Ichijou and Mai Kawakami are two of those that were granted such power as Haruhiko wields the ability to summon and seal phantoms through drawings while Mai imbues the power of the elements into martial arts. Together, along with the friendly phantom Ruru, they form Team E of Hosea Academy which is dedicated to dealing with these often mischievous beings. In a world where the real and surreal intertwine, Musaigen no Phantom World follows the adventures of a group of friends as they handle the everyday troubles caused by phantoms.
