Maya Young

Maya Young is young woman who is investigating the mysterious disappearances and believes in conspiracies, getting caught up in the Kamen Rider battle. She is a member of the website WayAboveTopSecret.com, which is themed around conspiracy theories and strange anomalies, especially those centering around the Mirror Monsters. To this end, she enlists Kit's help in uncovering the mysteries surrounding Ventara and the Mirror Monsters, although Lacey thinks she's just trying to ask him out.

Due to her attempted abduction by one of the Newt Monsters, she is able to see the Mirror Monsters when no one else can.

Following an attempt to flush out a Kamen Rider by staging a monster attack, Michelle Walsh snapped the pictures of the attempt and Maya is fired from the website. Maya has since distanced herself from the reporter and continues her pursuit of uncovering the mysteries of the Kamen Riders. She finds that her information was stolen and in response, deletes her work as a paranormal investigator so that she would not get targeted by the feds.

While discussing how to counter Xaviax's plans, Eubulon reassigns the Siren deck to Maya to help Len while he goes to retrieve the other Riders. He gives her the ability to fight by installing the memories of the previous Siren owner, Kase. She's now the second Kamen Rider Siren. She later meets Chance, Price and Hunt, some of the original Riders. Due to her past experiences with JTC, she feels uneasy around Price despite his attempts to befriend her.

Maya Young is portrayed by Aria Alistar.
