We, the Digimon Hunters!

It is a year since Taiki Kudō's (Mikey Kudo in english) adventure in the Digital World as he forms the "Xros Heart" (Fusion Fighters) basketball team together with Yū Amano (Ewan Amano), who became his junior at his school, and Tagiru Akashi, the new main character. However, on his way home from the game, Taiki sees a monstrous shadow within a space fluctuation before being confronted by three children.
