Emu Bugster surgery

Emu Hojo's surgery

In 2010, Emu Hojo was abducted by the Next Genome Institute, who had been hired by Kuroto Dan to remove the now-mature Bugster virus from Emu's body. After the matured Bugster later known as Parado was successfully removed from Emu's body, the members of the Next Genome Institute vanished and believed to be dead. As Michihiko Zaizen explained in his encounter with Emu, he and his fellow researchers were sent to the Game World and reborn as Bugsters only to return 6 years later with plans of revenge. Zaizen also mentions that Proto Gashats can somehow sent their user to the Game World, as he tries to send Emu in "same hell he suffered" by inserting Proto Mighty Action X Gashat in his Gamer Driver along with the standard Mighty Action X Gashat, resulting in Emu's transformation into his new form.

Failed Return of Kuroto Dan

Emu reappears in this world, soon meeting Kaoru Kino/Another Agito, Kazuma Kenzaki/Kamen Rider Blade, Kaito Kumon/Kamen Rider Baron, Yoko Minato/Kamen Rider Marika and Kiriya. The six do battle with a being known as Totema, but Another Agito, Baron, Marika and Lazer are all overwhelmed, while Kenzaki turns out to be somebody else as he mortally wounds Emu and Totema gives him a Game Over.

Game world ending

World ending

When Emu re-enters the world, he reveals that the Kenzaki standing before them is actually Dan Kuroto/Kamen Rider Genm. The real Kenzaki eventually shows, due to Dan's use of Undead powers, and the world soon begins to crumble. Kenzaki proceeds to reveal that, by nature of him being the only Undead in the Game World, he has been declared the winner of the Undead Battle Fight, which will result in the world's destruction due to him being the Joker Undead. Dan proceeds to fight the six and, after getting a power boost, Emu gives the other five Riders the power to become the GoRiders. They manage to defeat Genm, but he attempts to take the lives of Emu and Kenzaki. Lazer, Baron, Marika and Another Agito sacrifice themselves to allow Ex-Aid and Blade to get out safely. The world's fate after these events is presently unknown. Maze 3: Gorider Forever

Power of Level 0

Poppy Pipopapo was having visions from the memories from her host, where one of them was a young Kuroto told the host that he was developing a way to prevent Bugster infection, so Poppy went to investigate Kuroto's abandoned game studio. Suddenly, a vision of a young Kuroto was passing by, Poppy follows the vision, leading her into a hidden room.

There was a treasure chest in the room, containing a brand new Gamer Driver and the Proto Mighty Action X Origin Gashat. There's also a manual right next to it.

Ex-aid 29-63

Poppy sees a treasure chest and a Level 0 Manual.

Poppy later brings what she found back to CR, telling the others that Level 0 has the ability to nullify a Bugster's powers. Believing that this is the way to save Emu, she activates the Proto Mighty Action X Origin Gashat and enters the game itself via its title screen. In the world of this game, she finds a Bugster Virus grunt, which turns out to contain data on Kuroto himself. Poppy later attaches the Gamer Driver on the grunt and inserts the Gashat, restoring Kuroto completely, albeit as a Bugster. After which, Kuroto declared he was truly immortal while madly laughing gleefully. Kuroto then transforms into Genm Level 0 and heads to the Next Genome Institute operation theater where Parado is about to finish off Emu. Surprising everyone with his presence, Genm proceeds to attack Parado. Parado then attempts to possess Emu, but fails due to Level 0's Bugster-nullifying effect.

Back at CR, as Poppy explains how she brought Kuroto back, Kuroto proceeds to threaten the doctor Riders once more, though he is hindered by Poppy absorbing him into the Bugvisor II as punishment, due to his status as a Bugster. Strongest VS Strongest!
