Seishin Nadia is a powerful goddess within the Akuma vs. Tenshi Seal series. She bestows two young gods upon the leaders of the Tenshi and Akuma factions: Super Zeus to Shaman Khan and Black Zeus to Shiso Jura. When Shiso Jura consumes Black Zeus to amplify his power and launches an attempt to conquer the world, Seishin Nadia responds decisively. She cleaves the planet into two distinct halves, creating a physical separation between the Tenshi and Akuma realms. This act establishes the fundamental division between the factions. Additionally, Seishin Nadia empowers Saint Phoenix, transforming him into Head Rokoko. Her pivotal role in delivering the Zeus beings and subsequently dividing the world forms the origin story for the Tenshi-Akuma conflict, depicted in the film *Bikkuriman: Daiichiji Seima Taisen* and referenced in the video game *Bikkuriman World: Gekitō Sei Senshi* where her actions initiate the global split.
