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

White Coat License (白衣のlicense Hakui no Raisensu) is the forty-third episode of Kamen Rider Ex-Aid. It features the debut of Gamedeus Cronus, Super Gamedeus, and Taiga Hanaya's first appearance as the second Kamen Rider Cronus.


Suddenly, the Gamedeus virus begins spreading through the streets! Masamune becomes Gamedeus Cronus and appears before the other Riders, as he summons Nico into the World of Kamen Rider Chronicle! Nico is the one who is qualified to challenge the Last Boss of Kamen Rider Chronicle as a Ride-Player, but it seems clear that Masamune is going to try to Game Over the player who is closest to beating the game in order to reset it. In an attempt to save her but unwilling to let the others follow, Taiga uses the Chronicle Gashats seized from patients and goes to find her. However, the other Riders cannot enter the World of Kamen Rider Chronicle! Just what will happen to Nico's fate?


Kuroto proclaims that he has become a good person and now wishes to help the CR doctors protect the future…asking to be let out of his digital cage; no one's buying it. Suddenly, Kiriya collapses from the game illness, Emu diagnosing a new stronger version of Gamedeus' virus, Hiiro reporting that all patients from the last incident have gotten sick again, writhing in pain. The new "Masamune" confronts Taiga and Nico as they tend to Riku and his mother, transforming into Gamedeus Cronus, the combination of the ultimate villain and the only hero who can stop them. Taiga transforms to Snipe Simulation Gamer Level 50, but can't scratch Gamedeus Cronus, who uses Pause to knock him down before Ex-Aid Muteki Gamer and Brave Legacy Gamer Level 100 step in. He easily fights both of them, using Pause to move Ex-Aid into the path of Brave's attack before hitting them with Aranbura's Fracture spell. Ex-Aid uses Maximum Mighty Critical Finish to Reprogram away Gamedeus Cronus' ability to transform, but it is blocked with no effect by his shield. He jumps forward and hits the Riders with Graphite's Crimson Burst Draconian Blade, knocking Snipe and Brave out of their transformations. He then announces that the only one with the right to challenge him is Nico, a Kamen Rider Chronicle screen sweeping by and absorbing both him and her.

At CR, Kuroto reminds them that the rules of Kamen Rider Chronicle say the Ride-Player who collects the Gashatrophies can challenge the final boss. Nico finds herself in a large cement cave in the woods, the Game Area for the final boss battle. CR concludes Masamune is trying to kill the only player close to winning the game, Kuroto saying none of them have qualified to become Cronus and enter the Game Area. Gamedeus Cronus tells Nico that to win she must become Cronus and defeat him; it's Game Clear or Game Over. Taiga takes out the Kamen Rider Chronicle Gashats CR has been collecting from treated patients, vowing to stop Masamune himself and triggering one, putting it in his Gamer Driver and disappearing. Nico accepts the challenge, triggering her Gashat once, but Taiga appears and stops her, taking the Gashat; Hiiro realizes Taiga's five years with his Driver compatibility virus sample gave him the chance to build more immunity than most, letting him enter the Game Area. Taiga uses Nico's Gashat in his Driver's second slot and transforms into Cronus Chronicle Gamer, attacking Gamedeus Cronus with the Gashacon Magnum, soon switching to the Breaker. Hiiro says Taiga's always fought without self regard and knows the fate of doing this, but Emu doesn't want him to give his life for this or for him or Nico to get hurt; Kuroto inserts that he can, if he were let out, craft a cheat code to get them into the Game Area. With all the talk of people putting themselves on the line, Parado ponders how he can make up for his past actions; Poppy tells him to do it by ending Kamen Rider Chronicle.

Cronus (Taiga) swaps for the Gashacon Sword but loses it in one hit, taking the Sparrow to again lose it quickly, finally getting the Magnum into Gamedeus Cronus' face and bringing the two of them to a stop. Gamedeus Cronus says Taiga hasn't properly mastered Cronus' power, triggering Critical Crews-Aid as Cronus (Taiga) responds with Rider Critical Crews-Aid; the two attack hit each other but Gamedeus Cronus' breaks through, knocking Taiga out of his transformation. Taiga crawls in front of Nico, willing to protect his patient to the end even over her pleads to stop; even with no license, he still wants to be a doctor. Hiiro and Emu arrive through the "divine intervention" of "God Kuroto", telling Taiga if he wants to be a doctor to take better care of himself; doctors need to be healthy themselves so they can properly take care of their patients. Hiiro says the team operation to excise Gamedeus and Cronus is beginning, Emu offering Taiga the white coat of the doctor he is; Taiga accepts. The team transforms to Ex-Aid Muteki Gamer, Brave Level 100, and Snipe Level 50, attacking. Gamedeus Cronus uses Pause to put Ex-Aid between Brave and Snipe's attacks, but upon Restart, Ex-Aid as planned deflects both of them at Cronus; Ex-Aid and Brave duel Gamedeus Cronus as Snipe shoots around them before they knock him away with a double slash. Their teamwork is overpowering an angered Gamedeus Cronus, Taddle Critical Finish and Hyper Critical Sparking knocking him into a point blank Bang Bang Critical Fire, knocking them out of the Game Area.

However, when the doctors claim the fight to be over, Gamedeus Cronus laughs that they know nothing of games. Kiriya and all the other Gamedeus patients suddenly turn into Bugster Viruses, stumbling around and infecting everyone else they touch into more Viruses; a pandemic has begun, and Gamedeus Cronus grows into Super Gamedeus, a gigantic Gamedeus with dragon heads for hands. Whenever defeated, the final boss of Kamen Rider Chronicle will evolve to become stronger, and humanity is invited to play again and again to its heart's content in this eternal game with no ending.
