Movie
Description
Kenji Seki, a high school student living with his grandfather and younger sister, walks his dog on the beach every morning. There, he observes his classmate Kahori Harukawa surfing, struggling to confess his feelings for her. He shares a close yet contentious relationship with his neighbor and childhood friend, Natsuki Suzuura, marked by frequent arguments and teasing. Despite appearing absent-minded and habitually tardy, Kenji displays underlying intelligence through his room filled with mechanical inventions and construction plans.

His life shifts dramatically with the arrival of transfer student Ryoichi Kyogoku. Kenji witnesses Kahori developing feelings for Ryoichi while simultaneously experiencing emotional distance from Natsuki whenever he discusses his romantic interests, creating a complex relational triangle.

Unknown to Kenji initially, latent psychic abilities were sealed within him during childhood by his grandfather. This sealing followed a life-threatening coma incident where Natsuki sacrificed her own psychic potential to ensure his survival. When Ryoichi begins recruiting students with psychic capabilities for a mission tied to humanity's future survival, Kenji remains passive during Natsuki's initial withdrawal from school. He only intervenes when Ryoichi recruits Kahori.

The revelation of Kenji's sealed powers occurs during confrontations with Ryoichi, who reveals himself as a time traveler from a future where psychics inhabit the moon. Kenji's grandfather unseals his abilities, acknowledging their necessity for the escalating situation. Kenji's unlocked powers position him as a counterforce to Ryoichi's objectives.

In the climactic confrontation, Kenji disrupts a battle between Ryoichi and his familiar—later revealed as Ryoichi's father—by saving Ryoichi's life, demonstrating his compassionate nature. Kenji then volunteers to accompany Ryoichi back to his future timeline, seemingly disappearing from his own time. His departure leaves amnesia regarding the supernatural events in Natsuki and Kahori's wake. Kenji reappears after the credits, returning to his original timeline and restoring the memories of those affected.
