...
Decades ago, a hero from the stars left this world in peace. Now, the son of Ultraman must rise to protect the Earth from a new alien threat.
Shinjiro agrees to help test out and develop a new suit better adapted to his changing powers — and he finds himself using it much sooner than planned.
He can't remember what he did, but Shinjiro's forbidden from wearing his suit for a while. His father can't help but feel that there's an Ultraman curse.
Determined to do something, Shinjiro heads out to get his revenge. But then once again, he wakes up with no memory of what happened.
Public sentiment has turned completely against Ultraman. Then suddenly, Mephisto hijacks the airwaves to deliver a message directly to the people.
Ide sends Taro and Moroboshi out to search for Shinjiro, who remains on the run, confused by everything that's been happening to him.
Back in his hideout, Daisuke Arashi tells Shinjiro about his father's past, and they try to narrow down who Mephisto's next target might be.
After getting devastating news, Rena meets with Seiji Hokuto. Shinjiro talks to Daisuke about the strange dreams he's been having about Zetton.
Rena can't understand what just happened to her, so Seiji brings her to meet the alien who raised him. Taro finally finds Shinjiro.
Jack shows up, surprising Taro and Shinjiro. Rena seeks some answers about where her powers come from. The SSSP gets raided by the police.
The fight against Mephisto only strengthens the anti-Ultraman sentiment. Moroboshi and Shinjiro try to break into the heavily guarded SSSP headquarters.
Shinjiro and Rena reveal some secrets to each other. Joined by his friends, Ultraman faces a powerful enemy from the past.
As Shinjiro struggles in his own fight, his friends put everything they can into defeating Zetton. A new chapter begins for the SSSP.
