One element from the plot I did find somewhat puzzling was how totally glossed on the side story with regards to the original DigiDestined, that precede the people we see in Digimon Adventure, that was introduced in Chapter 4: Loss, but wasn’t given much screen time considering how important it seemed to be to the franchise all together. I was expecting for Coexistence to Digimon Masters Online Tera shed a lot more light on that whole plot thread, yet we have a meagre two scenes, and also the whole thing seems to search nowhere, and I’m fairly certain that whole subplot is completed with. I won’t spoil anything, but it really does appear like very little was achieved by showing us any one this, a shame. It’s a neat concept, but without actual substance, it makes for more filler.
As I have go to expect through the Tri franchise, action in Chapter 5: Coexistence is sparse, but I’m not overly bothered from this, as I prefer to see them focus within the story and characters than an over-abundance of flashy action DMO Tera set pieces. That being said, once we do start to see the Digimon tussle, it's, as usual, pretty spectacular. In this entry, our climax sees a four way free-for-all between mega level Digimon, and that is every bit as exciting to watch the way it sounds.
