Kamen Rider Ex-Aid: Chronicles of a Lone Ride-Player

Kamen Rider Ex-Aid: Chronicles of a Lone [Ride-Player] (仮面ライダーエグゼイド: 孤独のクロニクル [ライドプレイヤー]) is a Japanese tokusatsu drama in the Kamen Rider series created by Toei Company and Ishimori Productions. Made as an alternate retelling of the second half of the events of Kamen Rider Ex-Aid, it was produced for a full run after the success of Kamen Rider Ex-Aid in Japan, and worldwide. Beginning its airing on the 5th of January, 2019, Inoru Toki writes and directs the show in his first ever Kamen Rider series, alongside returning writer Yuya Takahashi (who was the main writer behind the original series).

The taglines of this spin-off are "Game start!" (ゲーム開始!) and "Defy the rules of fate, and explore the endless paths of destiny!" (運命のルールを無視し, 無限の運命の道を探る!). The main motif of the series is video games, and retro video gaming in particular.
