Yoriko has plans to get Ken and Miyuki together with amusement park tickets.  They go but so do Yoriko, Natsumi, Aoi and the Chief to keep an eye on them.  The spies are discovered and so the six of them go to a monster hunt attraction.  They must use paint ball guns to get to the goal against a crazy monster leader who thinks that love requires self sacrifice - and means to prove that no one does that anymore.
