Gold coins, jewels, you name it—Till the pirate has everything. Having acquired all he ever wanted, he hears an intriguing rumor. They say that hunting a 'Siren,' a creature with a voice that enchants humans, grants eternal life. Lately, they have become the prime target for pirates. However, not a single pirate has succeeded in the hunt yet. Intrigued, Till sets sail with his crew.

But even after months of sailing, he hasn't seen so much as a single mermaid scale. 'Is this all a lie?' Till mutters to himself. Leaving his drinking crew behind, he goes off alone to explore a cave by the night sea.

Suddenly, a beautiful melody echoes from deep within the cave. Does someone live here? He takes one step after another toward the sound, when suddenly, his body feels weightless.

"Aaaagh!!"

Thud! He falls awkwardly into a pool of damp water. What happened? Looking up, he sees a fairly large hole. 'How did I miss that? Was I possessed or something...?' He lets out a deep sigh and turns around, only to freeze in disbelief.
