Woman of the Beginning

The mysterious girl (謎の少女) is a humanoid female who came from a terrible future. She appears to look just like Mai Takatsukasa, except for her blond hair and heterochromia, suggesting that she may be Mai's future self. She and DJ Sagara might knows each other.

History
In a potential future, she was awakened by the ceremony of various Armored Riders' factions. However when her flower from her head was blown away by a strong wind, the Gaim and Baron factions charged at each other as the Zangetsu faction looked on.

She later re-appeared during Kota's fight as Armored Rider Gaim against Byakko Inves. She talked to a confused Kota, who mistook her for Mai, before helping him destroy the Inves, only to disappear afterwards.

She then later appears to warn Armored Rider Baron, telling him about his fate, but he ignored her, proclaiming that only he can decide his own fate.

She later appeared in Mitsuzane's dream and told him the fate of using the Sengoku Driver. He tells her that he can handle the burden of the belt's power, before he wakes up.

After Kaito leaves, she appears in front of Mai and tells her about her fate staying in the city.

She appears in Kota's dream as she told him that he still have a chance to change his fate. While Gaim invades Yggdrasill, she was curious why Sagara convince Kota to continue fighting as he already knew her identity.
