According to the rumored information, Kamen Rider Ex-Aid's civilian identity is of a young first-aid worker. Once he transforms into Ex-Aid, his main color is white and red with "siren eyes" similar to the ones found on top of an ambulance.
If Kamen Rider Ex-Aid's registration is similar to Kamen Rider Ghost, hopefully we will get our first concrete information about his transformation device and primary weapon in just a few days. Take note, Kamen Rider Ghost's trademark registration surfaced on May 26, 2015 and the trademark registration for his arsenal surfaced on June 3, 2015.
