The train of time, DenLiner. Will its next stop be the past? The future?
The world of KAMEN RIDER DEN-O is a world of Heroes and Villains, a world where the memories of the past dictate the path of the future. One day, an unassuming young man named Ryotaro Nogami finds a small item called a Rider Pass, which allows him to transform into a Kamen Rider, an armored warrior charged with defending the flow of time. With the help of Yuuto Sakurai, a figure from his past chosen as the mysterious Kamen Rider Zeronos, and Hana, a figure from his future with a grudge against the enemy, Ryotaro seeks to defend time and those important to him from the menace of the monstrous Imagin, as the mighty Kamen Rider Den-O!
