Re-reading this while on ski trip, DAMN is this route short. The common route scenes are all but one about Otonashi being taught ukemi, so you can pretty much skip right to Episode:Matsushita. If this was in English, it’d take like 2-3 hours to read. The route is actually just 2/3rds backstory and a conclusion.
I probably would never guess that this was the Kashida route. My image of Kashida mostly comes from how he does foreshadowing, but there is barely any foreshadowing in this route. There’s a blink-and-you’ll-miss-it line foreshadowing the misconception about sunflowers turning. Instead, I’d probably say the biggest strength of the route lies in its immersion(Sure wasn’t the plot). Because they keep visuals to a minimum, we get a lot more traditional text-based environmental immersion which also plays in with the theme of taking vision for granted.
There’s another important part to this route even though it’s soured slightly over the years: how it relates to the rest of Angel Beats!. First we got how Godan actually has a lot of things figured out similar to Yuri and Kanade. He’s spent decades in that world after all; it doesn’t make sense to not learn anything from everything around him. Hopefully, the same would hold true for the other characters. Second, this route kinda feels like a tutorial. Otonashi’s plan is retarded; it’s Kanade-level dumb even though he’s supposed to be the brain to her brawn. However, it works out in the end, but the story acknowledges that it was basically a stroke of luck, and Godan emphasizes that Otonashi’s got a whole lot more ahead of him… crickets chirping …Awkward…
