But she… is now a mermaid!?

Centered on legends and stories of mermaids, an incredibly unique summer vacation with Ion, Petakko, and Rin now begins…
Ion CV: Mai Fuchigami / Jung Hyewon
A childhood friend of the protagonist and the main heroine, she was a mermaid when he returned home.
She is a shy girl and usually finds it hard to express her feelings to others, but when she’s with the protagonist, she sometimes uses her tail to express how she feels…
By hitting him with it!
Petakko CV: Aya Suzaki / Cho Kyungyi
Another mermaid girl Ion and the protagonist meet.
She appears to be a bright and outgoing girl, but for some reason she’s very forgetful.
In fact, she can barely even remember what happened yesterday…
It’s currently unknown if this is a normal part of being a mermaid, but she doesn’t seem to mind it.
She lives her life to its fullest extent.
Lin CV: Risa Kasama / Kim Hayoung
A priestess of a 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 is in charge of taking care of them.
She’s also incredibly strong for her looks and, as a priestess, she can become possessed by the shrine’s deity.
It’s like she has two completely different personalities!
