Summary and Preview
A group of Coast Guard trainees undergoes a grueling training course in the hopes of joining an elite team of search and rescue scuba divers in Umizaru. Their drill sergeant, Hara, is as taciturn and demanding as they come, and a few trainees distinguish themselves quickly. Senzaki and Mishima are clearly the strongest and the toughest, while Kudo is the runt of the litter. Hara teams the cocksure Senzaki with clumsy Kudo, and the pair have trouble completing their missions. Kudo continually slows Senzaki down, but they share in the punishment. While the rest of the trainees openly mock Kudo, Senzaki defends him and tries to inspire him.
