Plot
A sky-blue mermaid-like creature comes to invade the surface world for fun. However, she ends up working at the local beach house.

Why It Sucks

 * 1) The Characters Have Been Flanderized
 * 2) * Squid Girl has gone from wanting to invade the world to want to use her tentacles for tickling and one point rape
 * 3) * Eiko's personality has been dialed up to 11
 * 4) * Chizuru is no longer the secretly scary girl but rather a sweet girl major facepalm
 * 5) * Sanae has become a simp
 * 6) * Nagisa has become a scaredy cat
 * 7) * Cindy Campbell has become a mad scientist
 * 8) * Takeru, Goro & Nagisa have become minor characters
 * 9) On that note, the male characters have their original personalities, while almost all of the female characters were changed, which comes off as a sexist lesson males can't be flanderized while females can.
 * 10) They cut out Squid Girl's squid talk because they said it wouldn't be localizable.
