The two Riders then see Geiz's Time Mazine and wonder what is going on as it lands. At Seito University Hospital, Geiz gets right to the point and tells Emu and Hiiro he is from the future and someone is trying to alter the past and their Rider powers will fade away if they don't stop it. Hiiro, being a no-nonsense person, thinks that Geiz is just crazy or delusional and will not buy his "fantasy story" and walks off. Geiz finds Hiiro's reaction a bit cold, but Emu remarks that the time traveler isn't much different from him based on what he has seen.

Personality
To be added.

Abilities

 * Genius Surgeon: Although he is only 24, Hiiro is a skilled surgeon, considered by many to be a genius in his field. He specializes in heart surgery, although he is capable of performing other operations.
 * Adaptation: An extension of his intellect, Hiiro has shown to quickly learn new concepts to make up for a previous failure. This was seen early on in the series when he first had difficulty with the rhythm mechanic of a game, but started using said mechanic to full effect by employing CPR rhythm to maintain the pace of his attack.
 * Swordsmanship: Hiiro is shown to be capable in using swords, comparing them to scalpels. This can be seen when he decapitated a Giant Bugster using a generic sword. This also shown as when he sliced a cream puff in episode 6, he didn't bring the knife in contact with the cream puff, but still equally cut into 4 pieces.
 * Acquired Game Disease Immunity: As a result of the standard compatibility surgery for CR candidates, Hiiro Kagami is immune to the Game Disease, and able to transform into a Kamen Rider to fight the Bugsters. Unlike Taiga, Hiiro's initial uses of higher-level Gashats inflicted physical damage, and strained his body until he acclimated to the power.
