Several years have passed since the events of Ultraman, with the legendary "Giant of Light" (光の巨人 Hikari no Kyojin) now a memory, as it is believed he returned home after fighting the many giant aliens that invaded the Earth. Shin Hayata's son Shinjiro seems to possess a strange ability, and it is this ability, along with his father's revelation that he was Ultraman, that leads Shinjiro to battle the new aliens invading the Earth as the new Ultraman.

Shinjiro Hayata (ULTRAMAN)

Voice Actor: Ryouhei Kimura

Shinjiro is the main character of this story and is the son of Shin Hayata, the original Ultraman. He is 17 years old. Due to inheriting genes of Ultraman from his father, Shinjiro has a superhuman power. He originally dons the Ultraman suit in order to save his father and fight enemies before becoming involved with the SSSP. He has feelings for his idol Rena Sayama, but he’s really just your average high schooler on the inside.

Dan Moroboshi (SEVEN)

Voice Actor: Takuya Eguchi

Dan is also a youth who belongs to the SSSP. He resembles something very close to a human, but is actually an alien. Just like with Shinjiro, he, too wears Version Seven of the Ultraman suit to fight. Unlike Shinjiro, Dan is merciless in battle against his foes.

Seiji Hokuto (ACE)

Voice Actor: Megumi Han

Seiji is a first-year student at Shinjiro’s high school. After losing his parents in a massive accident, he too was severely injured. He underwent surgery at the hands of aliens and become a cyborg. He fights with the suit, ‘Ace Suit’. He knows the true identity of Ultraman, Shinjiro, and Seiji hopes to be allowed to join the SSSP, referring to Shinjiro and his friends as ‘onii-san’ and ‘senpai’. At the same time, he steals money from evil beings and companies in their society who blackmail others, and uses it to fund Ultraman’s activities.
