Equipped with the Gashacon Hammer, which can also transform into a sword, he saves people who were infected by the Bugsters' viruses.
As what was previously reported, Ex-Aid is not the only Rider appearing the show. Also introduced in Kamen Rider Ex-Aid's debut month are Kamen Riders Brave and Snipe.
Next is Taiga Hanaya (played by Ukyo Matsumoto) aka Kamen Rider Snipe. He is an unlicensed doctor who will use any means just to win. Using his own Gamer Driver and the BangBang Shooting Gashat, he transforms into Kamen Rider Snipe. Equipped with the Gashacon Magnum, he will put down those who will stand in his way.
Now for the show's support cast, first is Kuroto Dan the president of the Genm Corporation, a gaming company and the man who hid the Kamen Rider System away. Now for the hospital crew, Hiiro/Brave is not the only Kagami working at the Seito University Hospital. His father, Haiba (played by Hanamaru Hakata) is the hospital's director.
Finally, the show will introduce us to two Bugster executives, Pallad (played by Kai Shoma) and the Graphite Bugster. Pallad is an intelligent Bugster member who wants to turn the human world into the game world, while the Graphite Buster is a hunting game software who is more powerful than Ex-Aid.
Kamen Rider Ex-Aid is set for an October 2 premiere.
