——An accident occurs at a deep-sea training facility.
About
The Deep Sea Rescue Team is responsible for handling accidents and rescuing survivors in the deep ocean. Years ago, it was Guest who saved Kyoya when he was caught in a maritime disaster. He has never forgotten the hand reached out to him in the dark depths of the sea. ...One day, I want to be someone who can save others, too. Driven by that goal, he pursued a career in the rescue team and has finally reached the final exam for enlistment. Guest is assigned as an assistant to the examiner, monitoring Kyoya and four other candidates from the mothership. They were to dive into the deep-sea training facility, complete their tasks, and return. ———That was all the exam was supposed to be.
