Digimon Adenture Tri Part 4 is a six part anime film that is a continuation of the original Digimon Adventure. Tai and the gang are back, but now they’re in high school and a new group of Digidestined (Digimon Adventure 2) have appeared and they (original Digidestined) no longer have access to the Digital World.
However, the new group of Digidestined are now nowhere to be found. And Digimon have found themselves inside the human world again. The Digimon who happen to slip in are now much stronger than they used to be.
Tai and the group must now decide whether or not to save the world once again. Now more than ever Tai is unsure whether the group is actually doing the right thing. Extreme Spoilers: At some point their Digimon became reset and lost all their memories. The group believed they may have lost their partners forever in the last battle. They decide to return to the Digital World once again, before they become adults, to find their pals again.
Thus the fourth part of the film is called Shoushitsu (Loss). The office site for the film released a new 90-second clip for part 4. Make sure to check out the film, it’s pretty good. And it’s not as long as an actual series. Each part is about an hour and it’s more than worth it to watch if you were actually a fan of the show.
