Its been 5 years after Masaru departed to the Digital World but now a new evil is emerging. This digimon is known as Naesala, a digimon that wishes to be free of the Digital World and take over the one known as the "Human World". He is getting stronger by the day and the digimon are trembling from fear of him. Many have lost there homes to Naesala and his army.
Not too long ago, Masaru sent a message from the Digital World to tell them about a threat coming from the Digital World to the Human World. After this, Commander Satsuma gathered some of the former DATS members to rebuild DATS but he knew this wasn't enough. He was going to have to train the next generation of DATS. [Teachers are: Masaru{ThUltimateFighter}, Yoshino, Touma, Ikuto, Miki and Megumi.]
