This article is about a/an rider in Kamen Rider Ex-Aid.

Manjiro Doi (土居 万次郎 Doi Manjirō) is a Mighty Action X enthusiast who chose to enter Kamen Rider Chronicle as a Ride-Player (ライドプレーヤー Raido Purēyā) to play the impossible Cronus Capture Quest. The first to arrive at Seito District 9 alongside Hayato Tsuzuki, they were thankfully intercepted and stopped by Asuna Karino and Emu Hojo before they could engage and no doubt sustain a Game Over at the hands of Kamen Rider Cronus. When Ex-Aid was initially defeated, the pair were covered by the arrival of Snipe, Genm and Nico. Ultimately, Ex-Aid accessed the Muteki Gamer and defeated Cronus, freeing the Ride-Players. Perfect Invincible GAMER!
