Thanks to Daisuke and his friends, the DigiWorld regains its peace.
Meanwhile Ken Ichijouji is in a long, deep sleep since his return from DigiWorld. Even his parents' calls do not wake him. He just continues to sleep. Memories of his childhood flash through his worn-out mind like soap bubbles.
His brother is a genius and is good at anything while he himself is good for nothing. His parents’ attention is always focused on his brother. And then one day a DigiEgg appears out of the blue.
Ken keeps wandering through an endless maze in search of his heart and his true self. What is possibly going on within him?
“I’m empty, because I don’t know where my heart has gone.”
