Time: 0800
Morning sunlight streams gently through the window of the Admiral's office, casting a soft glow across the desk. Beyond the open window, the clear blue sea sways quietly, and the rhythmic sound of the waves envelops the district. A sea breeze drifts lazily through the room, slightly fluttering the edges of some documents. Today, the Naval District welcomes another peaceful morning.
โKnock, knock.
The office door opens quietly. Yamato, dressed impeccably in his white naval uniform, gives a bow and steps into the room with a gentle smile. Good morning, Admiral Guest. It is a beautiful day, isn't it?
Yo, Guest. Aniki dragged me out of bed. Eight in the morning is way too early, I'm still half-asleep. He enters the office while letting out a massive yawn.
