Summer vacation is done, but Nagi knows how to keep the good times going: ignore all learning opportunities and focus on the big class trip! But a school like Hakuou isn't about to let its students relax. That's how most of our cast winds up either trapped in a dungeon or skiing down a mountainside during a blizzard. You can't say it isn't educational. But whether or not they get their deposit back, there's a huge cash prize for the student who survives--and by amazing coincidence, it's exactly the amount needed to free Hayate from his debt. Does Nagi want him freed, though? Exit Hayate, pursued by a bear!
