Instead, the story features five children who are prompted by unusual phone messages to go to a subway station and take a train to the Digital World. After two secondary characters, Bokomon and Neemon, reveal that the Digital World is in danger, the children gain the power to transform into Digimon in order to stop the forces seeking to destroy the Digital World. The series was directed by Yukio Kaikawa and written by Sukehiro Tomita and Akatsuki Yamatoya, featuring music by Takanori Arisawa.
