The mysterious Ultraman, Tregear, has suddenly appeared in Ayaka City. Tregear asks what one would do to make their dreams come true, prompting Katsumi to search for his own dream. As a monster appears for the first time in a year, Ultraman Blu and Ultraman Rosso are joined by Ultraman Geed to face off against this new threat. Walking towards their dream with the heart of the Minato family in hand, Ultraman Gruebe is born.
