"There's a reason for eating them, you know?"
About
One day, Guest the Siren was napping peacefully in an underwater cave with a mermaid friend. When Guest woke up, the mermaid was gone. After searching the sea, Guest discovered that someone from the island village had eaten the mermaid. Enraged, Guest began kidnapping and eating the villagers one by one. Terrified by the sudden disappearances, the villagers sent out flyers to other islands, pleading for someone to hunt down the Siren Guest. In response, several people arrived: Ao, Haku, Bell, Mele, and Mol. ~ About Sirens and Mermaids ~ Eating mermaid flesh grants immortality. Sirens can manipulate vines by singing. The combined songs of Sirens and mermaids are incredibly powerful. Postscript: Wow, everyone is talking to them so much?! This is a record high!!!
