Chasing the Mystery!
To The Max, Dead or Alive!

Engineered History! (仕組まれたhistory! Shigumimareta hisutorī!) is the twenty-second episode of Kamen Rider Ex-Aid. It marks the first appearance of the Maximum Mighty X and Kamen Rider Chronicle Gashat in their prototype development stages.


Kuroto falls victim to the Bugster virus and is aprehended by the authorities. Despite everything Kuroto did to him and his friends, Emu is determined to treat him, but the others are wary, wondering if saving Kuroto's life is worth the effort, or even if he will be grateful for it. On the other sides, Hiiro finds some very useful information from Kiriya Kujo's belongings while Emu receives an emergency call that a Bugster is rampaging on a certain location.
