Ultraman and his comrades from M-78 (including a new Ultraman, Zero, the son of Ultra Seven) join forces with other allies to fight a massive army of giant monsters led by the evil Ultraman Belial.

Nodame and Chiaki mutually decide that it would be for the best if they parted ways for a while so Nodame can practice for an upcoming competition. However, when things don’t go her way, she gets impatient and depressed. While Nodame is away, Chiaki’s former pianist Rui Son returns to take her place. To make matters worse, Rui and Chiaki are set to play the song Nodame dreams of playing with Chiaki herself: Ravel’s “Concerto in G Minor”.
