The penultimate episode seen!
I don't want to run out of breath, so I'll be going step by step with this review.
And, it was all along an expected surprise that TOEI will sooner or later pull all the characters from the previous digimon series for a big, smash reunion. I mean they did for other franchises like Kamen Rider and Pretty Cure, for example.
And, the insert song, "We are the Legend Heroes" was top score to listen to.
Now, all remains just one more episode, and this series is finished.
