Do you believe in Mermaid? Siren? Kraken? Sea Monster? Giant Sea Horse Or even a Talking sea creatures? Let me tell you something... Everything is possible... The way they stared at me... Their sweet lullaby... I know I one of them... But monster. The one live up at the land. They... Were greedy with our treasure. Pirate. The most greedy creatures I ever seen in my life. I swear. After what they have done to me. I won't let myself fall for their lies. With my sword, I swear... I will protect the sea even I have to go far away from my family. With my lullaby... I swear I will make them fall into the dark despair... With my soul, I. Swear. They won't get that power. To control the truce. The monster... Reveal the Truth... -Cross-
