Another really good story from Rumiko Takahashi's mermaid series.
The animation was really good - even though it didn't look like "Rumiko Takahashi" at all. I like her simplistic but endearing and rather funny character design which has been missing here. The character design itself - epecially of Masato - reminded me sometimes more of Saki Hiwatari.
All in all it is a really good horror story with a nice twist.
