Kamen Rider Drive is the 2014-2015 Kamen Rider series; the sixteenth entry in the franchise's Heisei era and the twenty-fifth series overall. Riku Sanjo returns as the head writer after Kamen Rider Double. The Global Freeze: an infamous event in which the world came under attack by mysterious beings who caused time itself to slow down. Six months later, peace has returned but the world remains alert for future occurrences of the "Density Shift" phenomenon. Shinnosuke Tomari is a young and talented police officer who sank into depression and lost all motivation after he accidentally crippled his partner during the Global Freeze. Because of this, he has been reassigned to the "Special Investigations Unit", a division of Bunny Ears Lawyers specializing in cases involving Density Shift (known colloquially as "Slowdown") and other unexplainable phenomena. When the perpetrators of the Global Freeze, a series of rogue AIs called "Roidmudes", emerge from dormancy, Shinnosuke discovers that his car (and its sentient belt) gives him the power to move normally during Slowdown and battle the Roidmudes on equal terms. Shifting his life back into gear, Shinnosuke transforms into Kamen Rider Drive to take down the Roidmudes and solve the mysteries surrounding them once and for all.
