Hana (ハナ?) is a Singularity Point and the first Den-Liner passenger Ryotaro Nogami met, convincing him to become a Kamen Rider while explaining the uses of the Rider Tickets and the Rider Pass. She said that she fights so that she can protect and preserve the flow of time from the Imagin, and she made a contract with the DenLiner's Owner to do so. She originates from a future destroyed by Imagin chaos, still existing because of her status as a Singularity Point. With no timeline to call her home, Hana is filled with malice and spite towards the Imagin, making her capable of subduing the Tarōs when they get out of line, especially Momotaros with a simple punch to the head with force equal to a truck's. Ironically, Hana grew a soft spot for the Tarōs over the course of the series, briefly crying when Urataros, Kintaros, and Ryutaros disappear, though she refuses to admit it. Hana usually worries and looks after Ryotaro, treating him like a younger brother.
Over time, the tracks that represent Hana's future are being recreated, resulting with Hana turning back into her child form. Despite being in the body of a ten-year-old under the alias of Kohana (コハナ Kohana?), which Ryotaro gave her in the heat of the moment, she is still able to attend to the Tarōs' shenanigans aboard the DenLiner when they get out-of-line. In the finale, she is revealed as a daughter of Airi and Sakurai (thus being the niece of Ryotaro), the true key to the Junction Point and Kai's downfall as her new, recreated, future connects to the present. However, as her place in time is yet to be restored, Kohana lives on the DenLiner to await for her time. She becomes a member of the DenLiner Police at one time, aiding Kazuya Suzuki by taking out Kuroki's men singlehanded.
