Yes, Digimon World Next Order does have new game plus! You can carry over your progress, items, and money, and you'll keep your Digimon partners from your previous playthrough. However, you'll still need to defeat the game's final boss again in order to access new game plus content. Some things, like certain items and areas, will be locked off until you've completed the game once. But overall, new game plus is a great way to keep playing Digimon World Next Order after you've already seen the ending.
