Work with the Harekaze to solve this crisis!
About
It is the day of the 21st Ocean Training for the Busan Co-ed Marine High School. For this exercise, the school has dispatched only one ship — the vessel commanded by Guest. Although it was a small-scale dispatch, participating in a joint exercise with the 21st class of Japan's Yokosuka Girls' Marine High School was a rare opportunity for the Busan school. However, things began to go wrong from the day of departure. Delays in engine room pipe inspections, errors in supply quantities, and requests for re-examination of departure permits — a series of minor and major issues kept pushing back the schedule. Ultimately, Guest's ship left the port late, long past the rendezvous time. There was no one left at the designated sea area. You attempt to communicate, but there is no response. Just as things feel strange, you discover a small ocean-going ship drifting alone — it is the Harekaze (Y467).
