Ayuko is a character in "Dual! Parallel Trouble Adventure." There are two versions of Ayuko, Ayuko Sanada and Ayuko Rara.


In Kazuki Yotsuga's original world, known as World A, Ayuko was the wife of Ken Sanada and the mother of their daughter Mitsuki Sanada. However, Ayuko left them for unknown reasons though Mitsuki believes that she ran away with another man.

In the parallel world, Ayuko is the wife of Hiroshi Rara, the leader of the Rara Army, enemy to the Earth Defence Force (led by Ken Sanada) in their war between powerful mecha robots. In this world, she is the mother of Mitsuki Rara.

Ayuko Rara manipulates events while behind the scenes, posing as Rara's submissive wife. In reality, she controls the Rara Army along with the mysterious alien named Kumu. She exploits Mitsuki Sanada's love of Kazuki to convince her to turn against the EDF. Ultimately, both Ayuko and her robot Himiko are defeated by Kazuki and Zinv, the original core robot.

When Zinv is destroyed and the two worlds merge, Rara and Hiroshi move in next door to the Sanada family, hoping to corral Kazuki into revealing the secret of his connection to Zinv. In this new world, she somehow becomes the older sister of a reluctant Akane Yamano. When Zinv returns, Kazuki decides to use Zinv as a means of exploring outer space.


  • Ayuko's costume (and to a lesser extent, her phyisical appearance) resembles that of Seto Kamiki Jurai from the series Tenchi Muyo! GPX. Whether this means that they are parallel counterparts of each other has not been revealed.
  • Some fans have theorized that it's possible that Ayuko Rara and Ayuko Sanada are one and the same.
