Kamen Rider Siren
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. During a confrontation against several Mirror Monsters, Maya meets up with Adam who attempts to befriend the Earth Rider since he failed with the Ventaran Riders. She is put off by his attempts, though not once did he attack her. Kit later shows up, and after aruguing, Kit and Adam fight each other, though Maya wants them both to stop. After Kase comes back from the Advent Void, she returns the Advent Deck back to her saying that fighting as a Kamen Rider was one of the best experiences in her life, but her journalistic career comes first. Thus the Siren Deck passes from Maya back to Kase. She soon senses that something is wrong with Adam when he leaves with Len to the last transmitter, which is confirmed to be true. She also manages to patch the bad relations with Price realizing that Price and JTC, though they look the same, are two different people. Along with Trent, she manages to sneak inside Xaviax's base to allow the other Kamen Riders to infultrate the base as the shield surrounding it only allowed people who were not locked to an Advent Deck inside. There she witnessed the 13 Kamen Riders use their Link Vents and destroy Xaviax once and for all.
During the Epilogue, she makes a children's book detailing the events of the whole series, which she passes off as fiction promising to keep the Rider's identities a secret. It becomes a popular book as she is seen in a book signing, even meeting up with Kit, Len and Kase, with Len jokingly apologizing about her camera from the start of the series. Also, she starts dating Price who also visits her in her book signing
