Kamen no Maid Guy: Ano Natsu, Ichiban Yutaka na Chichi.

Naeka, Kousuke, Fubuki, Kogarashi, Eiko, and Miwa head to an isolated beach for what should be a quiet summer break. Their vacation quickly collapses when they disturb the lingering spirit of an ancient fisherman whose fixation on well-endowed women has survived far longer than he has.

When the spirit targets Naeka and the other women and attempts to place them under his control, Kogarashi's idea of protection once again turns a ridiculous crisis into destructive maid-powered mayhem. The deserted island soon becomes anything but peaceful.
