Digimon Frontier - Revival of the Ancient Digimon (2002)
After prompted to do so by unusual phone messages, the five main characters go to a subway station and take a train to the Digital World. Once there, they meet two secondary characters, Bokomon and Neemon, who act as guides, and tell the DigiDestined that the Digital World is in danger. They must fight the antagonist, Cherubimon and his Legendary Warrior servants before they succeed in dominating the world; it's up to the children to save it.
