Among the Ultraman in Showa, the happier ones are Ultraman Seven and Ultraman Eddie. Ultraman Seven later had a super powerful son, although it was not officially announced. His wife, but the son cannot be his own, and then there is Ultraman Eddie. His girlfriend came to the earth while he was protecting the earth and fought side by side with Ultraman Eddie.

It can be said that when two Ultraman appeared on the earth at the same time, only Ultraman Eddie was a man and a woman, and Ultraman Ace was not counted, because Ace was only a man and a woman, and Didn't become two Ultraman. Although Ultraman Eddie has fewer fans than others, I have to say that he is the luckiest. Ultraman Ace is more miserable. At the beginning, he was a fusion of two people. At this time, Ultraman Ace is the fusion of Hokuto Seiji and Nan Yuko, although there is a beautiful woman in his body. But he couldn't like her. Later, Nan Yuko and Hokuto Seiji separated, and Hokuto Seiji transformed into Ultraman Ace alone, and completely merged with Ultraman Ace.

Although Ultraman Ace could like her at this time, Nan Xizi went back to his hometown again, and the relationship just broke down. In Ultraman Mebius' TV, the two met again and confided that they had always loved each other. Always support yourself with your love for the other person.

In addition to Nan Yuko, Ultraman Ace also had a childhood sweetheart girlfriend when he was young. She was Ultraman Ludia. Maybe many people don’t know her because she is not on TV. Nakaba died at a young age.

She is one of the characters in "Ultraman STORY0". The initial setting recorded in the separate volume is that people with healing abilities belong to the Silver Crusaders. Together with Ultraman Ace, he was transformed into a superman by the influence of plasma sparks.

She is Ultraman Ace's childhood playmate, a female Ultraman. As a constant point observer, he was conducting interplanetary surveys, but fell into a trap by the Baltans and was transformed. After being transformed, he used Ultra's signature to lure the warriors from the Kingdom of Light, and Ace also fell into the trap. However, in the end, he committed suicide in order to save Ultraman Ace.
