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.

In modern-day Japan, 13-year-old Hajime Yasaka moves to the countryside to stay with his grandfather. On the way to his new home, a lost Hajime finds himself in a cafe called Ark, where he immediately falls in love with one of the waitresses: the gorgeous Sayoko Arashi Arashiyama. While Arashi is initially unconcerned with the boy, her attitude quickly changes after she grasps Hajime's hand, leading her to believe they are connected.

By touching a man she connects with, she gains the ability to travel back in time. Delighted to have found someone who can unlock her powers, Arashi asks Hajime to help with her mission: to save civilians from the carnage of the war that claimed her life. Smitten with Arashi, Hajime readily agrees. But as the two get further involved with Arashi's past, they soon discover that she is not the only one able to transcend time.
