The new story is set in the land of dreams and hopes known as Diginarsa, a realm whose very existence depends on the dream energy generated by humanity. As people across the world begin to lose their dreams and ambitions, this vital energy decreases, and Diginarsa faces the threat of disappearing entirely. As a last resort to save his kingdom, the king sends out his three loyal companions—Chamocha, Dettabook, and Pipirupi—to find help.

On Earth, a young girl named Momo is about to celebrate her twelfth birthday. Upon receiving a smartphone as a gift, she encounters the king's three envoys and awakens to her true identity as Minky Momo, a magical princess destined to protect the dreams of others. Resolving to save Diginarsa, she begins her mission to collect dream energy. However, her efforts become complicated when a mysterious new application grows wildly popular in the city. The dreams that children share within this app are not sincere aspirations but rather shallow fantasies driven by a desire for recognition, approval, and increased viewer counts. This trend leads Momo to begin questioning whether these superficial goals are the kinds of dreams she is meant to protect.

The narrative follows Momo as she navigates this modern digital landscape, confronting the difference between genuine hopes and fleeting, attention-seeking whims. She is supported by her three animal companions, who aid her in her quest to restore genuine dream energy to Diginarsa. The central dramatic arc involves her growing doubt about the nature of the dreams surrounding her, forcing her to reconcile her magical duty with the complex reality of a world increasingly influenced by social media and digital validation.
