"Within the shrine on this island... an ancient calamity has been sealed away." "Should anything disrupt that seal, then..."

Set in the archipelagic nation of Orien, students at the National Orien High Academy of Magic hone their sorcerous skills. Among them is the protagonist, Kuzuri Shirogane, who embarks on a school trip to Yuishima - an island where ancient tree spirits are said to rest - under the guise of field training.

Intrigued by an elder villager's tales of the "Tree Spirit," Kuzuri heads toward the local shrine, only to catch sight of a suspicious figure along the way.

Overcome by intense chills and dizziness, Kuzuri instinctively attempts to flee, only to find himself trapped within a supernatural barrier that prevents anyone from leaving. Breaking through by force is impossible, as guardian spirits appear to eliminate anyone attempting to breach the boundary. Separated from his classmate Nazuna and the others, returning home seems out of reach.

Will Kuzuri find a way to escape the barrier? And above all, who created this barrier, and for what purpose...?
