Rail Wars! manages to contrive a fairly logical reason to have a beach episode: Defense Four is appointed as the security detail of the pop idol Kashima Noa, who is having a concert on the beach in Izu in order to promote the National Railway, which so effortlessly, comfortably conveyed them to Izu. Wouldn’t it be nice to take a train with panoramic windows to the beach? I’m living in the wrong dang country!
Noa comes off as most idols initially come of in these kinds of situations: aloof and largely indifferent to her latest minders (she even dozes off as Naoto waxes poetic about the train they’re on being named after a famous short story “Izu no Odoriko”, for which there’s probably been an anime or two at some point.) But when they alight from the train at Ito station and an overzealous fan goes for Queen Noa, Naoto is there to stop him, though Noa and her manager end up making a Naoto sandwich.
It’s the latest in a series of incidents and threats, including one that promises Izu will be Noa’s final show, but this is where Noa shows her grit. She got to where she is by never stopping singing, and she’s not cancelling the concert under any circumstances. Since she’s not backing down, it’s up to Defense Four to protect her, and judging from their past exploits, it was never in any doubt that they’d succeed; only a matter of how they’d do so.
What struck me is that even in a beach episode where the camera spends an inordinate amount of time on various parts of the girls’ bodies, the show still sweats the practical procedural details. When talking about searching a place for dangerous people or objects in earshot of the public, its better to use euphemisms so as not to induce worry in said public. Iida also insists Defense Four and in particular the lovely Aoi and Haruka don swimsuits that make them stand out in a crowd; a clear, busty message to any bad guys around that they’re out in force.
The day of the concert arrives. After her first (very catchy) song, JNR reps join her on stage to make her an honorary security captain. The crim shows himself and brandishes a knife, but again Naoto is there to shield Noa from harm. The blade pierces his Kevlar vest (which all D4 members wisely wore while on duty) but is stopped by, of all things, the station stamp book Noa had returned to him after the sandwich incident that knocked him out. Because of that, in a way, after saving her, she saved him right back.
Aoi, however, fears the worst when she sees the stabbing, and treats the perp to a righteous take-down, not missing a beat despite wearing a sultry one-piece and flip-flops, not her preferred garb. It’s a very cute reminder that Aoi really does have a thing for Naoto, who once again was looking at another woman most of the episode. And all of Naoto’s dedication, courage, and heroism has the effect of successfully wooing the idol, making me wonder if she’ll ever show up again.
