As an archaeological investigator in this fictional maritime world, you will piece together a hidden truth using the ship's log, relics, and fragmented memories. You will then step into the role of the Captain of the Destiny, making crucial choices between forbidden love in the deep sea and moral duties on land. This is a choice-driven visual novel where every branch reveals another facet of destiny.

Story Structure: Two Core Narrative Arcs

The game is structured into two main components: the Prologue and the Main Storyline:

1. Prologue: The Destiny's Past (Background History)

• Perspective: The Archaeological Investigator.

• Content: Features five independent stories where you uncover the history and fate of the captain and crew of the Destiny through investigating background files and relics.

• This part is primarily linear, with choices serving to enrich character details but not affecting the final outcome.

2. Mainline: The Captain and the Siren (Core Experience)

• Perspective: The Captain of the Destiny.

• Content: This is the heart of the game, focusing on the complex entanglement between the Captain and the mysterious Siren.

• Mechanism: Player choices and actions will directly influence the affinity and trust levels of key characters, triggering different, significant story paths.

Core Gameplay and Mechanics:

• Choice-Driven Multiple Endings: Every major decision carries accumulative weight, eventually leading to multiple distinct ending branches. The game highly encourages replays to explore the unique paths.

• Characters and Dilemmas: Explore the emotional boundaries between human and non-human, balancing moral responsibility, crew safety, and personal forbidden affection.

• Narrative Puzzle: Combine the fragmented information from the archaeological investigation with the Captain's mainline choices to unlock the complete truth of the story.
