Other than Miki, Mitsuki Sanada's astral also forms the core of Kiriko Masaki, the Renza agent Karen, Tsukiko Masaki (Kiriko's mother and also the model for the AI that Hiroshi created and became Miki), and others. Other than Fuku, Yayoi Schwael shares her astral pattern with Amane Kaunaq, the Renza agent Gyokuren, Mikami Kuramitsu, and others. Other than Kirche, Mitsuki Rara shares her astral pattern with Ryoko Balta, the Renza agent Suiren, Ringo Tasuki, and others. Other than the D that is her astral copy, D/Dee shares her astral pattern with Neju Na Melmas, the Renza agent Hakuren, and others. When four of the girls that share an astral with their Dual counterpoint join Seina, his bad luck (described as a "biased probability" in the novels) is lessened and can even create good luck. Others that surround Seina, like Airi Masaki and Seto Kamiki Jurai probably represent other primary characters in Dual, such as Akane Yamano, Reika Nanjoin, and Ayuko Rara, but this has not been confirmed. Seto does have a separate "mirror self" called Kuis Panta that has been confirmed to share the D astral, but while they are practically copies of each other- they do not seem to share the same astral pattern. Cameo appearances Sasami and several other Tenchi Muyo! characters were featured in inserts found in the Dual! Parallel Trouble Adventure'' releases in Japan. Kiyone Makibi, Ramia, and Misao Amano appear in a brief easter egg cameo in the series' OVA special ("Final Frontier", also known as episode 14). Production Dual! was inspired by the popularity of Neon Genesis Evangelion when it aired in Japan in the 1990s with the main characters inspired by the dynamics of Shinji, Asuka, Rei and Misato. Media Dual! was released in Japan via VHS, Laserdisc and DVD from June 25 to December 22, 1999. A Blu-Ray version was released in Japan on October 11, 2018.
