It is revealed that she intended to use her position to covertly learn the truth behind the cover-up of an industrial accident at Namba Heavy Industries that killed her father and ten others. When Misora exposed her cover, Sawa is punished by being turned into the octopus-themed Stretch Smash before she is defeated by Ryūga with Sento extracting the Nebula Gas from her system. After that, she decides to atone for her actions and join forces with Sento's group to fight against Namba and Faust. During the time she spent with them, Sawa becomes protective of Misora, especially after learning of the younger woman's backstory. Sawa's father was a researcher working for Namba Heavy Industries. Three years ago, when Faust lost one of the panels of the Pandora Box, a gas explosion occurred at one of Namba's laboratories, with her father among the eleven researchers who had died in that explosion.

The explosion was supposedly set up by the Touto government to cover up the loss of the panel. In order to find out the truth behind her father's death, Sawa began working for Namba under the pretext of helping spy and gather information on Build. In reality, this was because she wanted to prove a connection between Namba and the Touto government.
Sawa came to Gentoku Himuro for information about the Smash, as well as his thoughts on the rumored Kamen Rider. Much to her disgust, Gentoku suggested "continuing the conversation" at the nearby hotel. Later that night, Sawa herself was saved from Needle Smash by Kamen Rider Build. When he canceled his transformation and walked away, he dropped a nascita card and Sawa was able to put two-and-two together.
Sawa and Sento later witnessed Touto's operation to take down Faust, where Nariaki Utsumi was seemingly exposed as "Night Rogue" and Faust's creator, before being gunned down by Gentoku Himuro. Regrouping at nascita, they found out that all the evidence gathered from Faust's hideout pinned everything onto Utsumi, with no implication of any involvement by Touto or Namba. Having believed that her job was done and that she was no longer needed, Sawa decided to leave, though she was persuaded to stay and continue helping Sento and the others, which she gladly agreed.
Alongside Misora, Sawa was a spectator at the proxy battle between Build, representing Touto, and Grease of Hokuto. Learning that Misora was holding Sento's killswitch which would break the Hazard Trigger at the cost of his life, Sawa rushed back to Nascita where she urged Banjo to intervene, leading him to save the lives of both Kazumi and Sento.
