Character History
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.

The next day, she visits the hideout after Soichi accidentally left their hideout door open and promises not to reveal Sento's identity on the condition that he gives her an interview. Later she gives them a photo of Nabeshima, the lead suspect in Ryuga's framing case.
