- Similar to Kamen Rider Scissors and Kamen Rider Tiger. Gai is a melee fighter who relies on brute strength and his intellect more often than anything else, Gai's attack methods usually involve his Confine Vent card to cancel any weapons from the other Riders while using the Metal Visor on his left-shoulder to conjure his Metal Horn gauntlet as well as summoning his contract monster Metalgelas to fight alongside him and execute his Heavy Pressure Final Vent, carried by his Contact Monster as a lance, with the Metal Horn extended in front of him to pierce through the opponent.
- Like other A.R. Ryuki Riders that appeared in Kamen Rider Decade, either his real identity or his full name never be revealed by Toei, but he only appeared in suit and voice.
