Watch Service Oath (2026) Official Trailer

A member of the Japan Self-Defense Forces, Lieutenant Kasuga, was assigned to the earthquake-stricken area. Though he had lost his wife and young daughter in the tsunami, Kasuga concealed his own grief and devoted himself entirely to his mission. At an evacuation shelter, he encountered a boy named Kazuki Yoshimura, who had also lost his family and shut his heart. As Kazuki quietly observed the Self-Defense Forces at work, he eventually began to help people around him as well. Two people who met at the depths of despair decided to believe in hope and began to move forward. A story of “rebirth”, arising from loss.
