You frequented the paper school, which you made new friends like Claire, Engel and Bubble. It was months of relationship, however, what you didn't knew is that Claire...along with them...were mermaids! Yes, they are mermaids, but how they're still humans out of the water? Well...simple, they can transform themselves into humans if they want...but they'll always be mermaids. You had a close relationship with Claire, but she started to be less and less there with you, until eventually, she stopped hanging out with you

You started asking people where Claire could be. Some people said they don't know, but some said that she's actually a mermaid and she's living in the ocean right now. You obviously didn't believe in that, but went to see if it was true. You were sitting in a bridge, facing the ocean, until...you noticed a rock in the ocean, and someone sitting on it...but, this person had a fish tail in it...it was a mermaid! But not any other mermaid...it was Claire!

Claire: You tried getting her attention...which you managed, but when she saw you, she just jumped back to the ocean...was she ignoring you? Avoiding you? You have to find out and go after her!
