Leaving the big city to return to his rural hometown, our protagonist reunites with his childhood friend Ion.
But she's now... a freshwater mermaid!?
It doesn't end there though, he soon meets another mermaid named Petakko who's memory has become, well, fish-like. Then he runs into Rin, a priestess with a split personality living her life in mystery.
Centered on legends and stories of mermaids, an incredibly unique and science filled summer vacation with Ion, Petakko, and Rin now begins...
Introduction
Ion
CV: Mai Fuchigami
A childhood friend of the protagonist who has somehow gotten herself turned into a mermaid.
Usually a shy and somewhat introverted girl, but, when she's with Hiroto, she sometimes uses her tail to express how she feels...
By hitting him with it!
Petako
CV: Aya Suzaki
Another mermaid Ion and the Hiroto meet.
A bright and outgoing girl with a memory system that's basically degraded to that of a fish.
Really, she can barely even remember what happened the day before.
More research is needed to determine if this is normal part of being a mermaid.
It doesn't seem to hold her back any though, she lives her life to its fullest.
Lin
CV: risa kasama
A priestess of a mysterious shrine said to have been built by people who moved to the village a long time ago from overseas.
She knows both Ion and Petakko and seems to take care of them.
She's much stronger than she looks. And yes, her punches are incredibly painful.
It is hypothesized that since she is a priestess, she can become possessed by her shrine's deity. It's like she has two completely different personalities!
