The girl standoff is defused in the ep’s first two minutes, which I thought was a good move. Goofy harems? Not so exciting. Emergency organ delivery runs via draisine? Way more exciting…not to mention topical! The story is simple: a storm has caused rockfalls and mudslides, knocking out rail service, but one of the train’s passengers is delivering an organ that won’t be viable by the time service is restored.
Enter D4, who are in earshot of the dilemma and are ready and willing to do what they can to get that organ to its destination. Naoto, Aoi, Haruka and Shou have the blessing of both Narita and a high-ranking JNR official, and are assigned to a vintage four-man draisine to make the trip along the abandoned but possibly open old line.
Naoto comes up with the idea, after Haruka offers to deliver the organ on foot, which is admirable, but would probably take too long. The draisine itself is a nifty mechanism in which to place D4: a small, temperamental machine in which the four members of D4 must work together as a cohesive unit, relying on one another’s individual strengths to traverse the not unperilous 11.2 km distance.
I also like how this draisine’s operation isn’t as simple as pedaling and braking, as D4 finds out. Due to time constraints, Haruka speed-reads the manual and fills in the others in transit. Notably, the numerous bends in the track make the little car lean to one side, requiring the muscle of the group, Shou and Aoi, to lean out of one side or the other to provide counterbalance.
It’s super-dangerous, daredevil work, but it’s absolutely necessary to prevent catastrophe, and neither hesitate in their task. Aoi even tears up her best dress in order to gain more freedom of motion. This crazy roller coaster ride turns out to be a far better test than any simulation without being as heavy a responsibility as driving a full-size train loaded with passengers. They still have lives to protect: their own, and one life to save: the organ recipient.
At episode’s end they’re halfway there, reaching the old part of the line fouled by branches, roots, and other obstacles. That is, the “easy part” is over, and it didn’t feel that easy, which means the hard part should be that much more interesting. What I know for sure is that this episode was a lot of fun, which along with the bomb threat and concert episodes, form the three reasons I’m glad I’ve stuck with this show.
