Hatafuri Mermaid

"I'm going to get her 'voice' for sure!" Unsatisfied with the bad ending of "The Little Mermaid" when he was a kid, Yoshitoshi decides to create a happy ending for the Little Mermaid in his own animation! However, he just can't find a voice actor to play the role of the Little Mermaid. But he suddenly hears an ideal voice. The voice belonged to his classmate Kohamo, who had also entered the same high school. However, she is a girl who never speaks, but instead uses "hand signals" to communicate...!
