Prologue: 'Revol'ution

No; this is not related in any way to the masterpiece entitled The Games we Play by Ryuugi. That is a RWBY masterpiece of fanfiction. This is some shitty dude writing Kamen Rider ex-Aid stuff. And trust me; it is shitty.

Summary:
A direct tie-in with Kamen Rider Ex-Aid. Nico defeats the Revol Bugster as Ride Player Nico, like in the series (episode 27 as reference) but Poppy dubs her as 'the second player to defeat a Bugster' and that Salty had already been defeated by another player. Who is this mysterious player, and is his agenda to help the Doctor Riders clear Kamen Rider Chronicle?
