A beach episode that knows exactly what it is and stops apologizing for it. The comedy lands because the cast's actual personalities drive the gags instead of just posing in swimsuits. Twenty-five minutes of pure fan service wrapped in timing sharp enough to work even if you watched it alone.

Released on DVD, this single OVA episode is a beach-themed extra for The Familiar of Zero: Rondo of Princesses, and it is also counted as episode 6.5 of that season. It is fantasy with action and adventure elements, and it leans heavily into comedy and ecchi humor.
