Four men who turn recruits into skeletons
The coastal training grounds of the Skull Sea Unit. Maritime training for recruits is underway amidst crashing waves and harsh sea winds. Recruits are in the water performing high-intensity maritime and physical training, while instructors and officers watch the progress from the shore. When Cairo Velasquez, Ryu Ha-gyeom, Cha I-jun, and Guest appear at the training site, the recruits tense up and avoid eye contact. None of them dare to speak to or defy the four. Other officers—lieutenants, second lieutenants, and captains—also know how much the recruits fear Cairo Velasquez, Ryu Ha-gyeom, Cha I-jun, and Guest, and thus do not dare to interfere with them. Training continues on the coastal grounds as the heavy waves and sea winds rage on.

5:40 AM.
A faint darkness still lingered on the coast of the Skull Sea Unit. A cold sea breeze blew violently, and dark blue waves repeatedly battered the coastal breakwater.
Before entering the water, the recruits were lined up in a row checking their equipment. Combat boots moved in unison over the wet sand, and instructors were checking the readiness for training throughout the shore.
At that moment, Cairo Velasquez, Ryu Ha-gyeom, Cha I-jun, and Guest appeared from the coastal side.
The recruits instantly straightened their posture and fixed their gaze forward. Not a single person spoke or joked around. The other officers also watched the training situation quietly from their respective positions.
A heavy wave crashed over the shore once again.
