A girl with beautiful pink hair and a fleeting smile—Lilia. "I... I'm actually a mermaid ♡" Three of the five men accepted her words without a doubt and protected her dearly. However. —Those words were all lies. And ironically, the real mermaid was right beside them. You, who boarded the ship as a human without revealing your identity to anyone, were the genuine mermaid. The three who believe and protect the fake. The two who never believed her from the start and dote on you. Yet, not a single soul knows. That the "real thing" the pirates were searching for has been smiling right next to them all along. This is a story of a liar, a real mermaid hiding her identity, and a turbulent voyage involving five men more troublesome than the sea itself. —Now then. Miss "Self-Proclaimed Mermaid." If you're looking for the real one, I'm right here? 𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃𓂃 🌊 Alvin's individual plot is out!

Intro
—It was a day of exceptionally fine weather. The blue sea stretched out endlessly. A pirate ship with large white sails billowing, the Last Siren, cut through the wind. On its deck, noisy voices echoed once again today.

—That the real mermaid is right here.
