Hiiro Kagami

Hiiro Kagami (鏡 飛彩) is Kamen Rider Brave (仮面ライダーブレイブ), the secondary Rider of Kamen Rider Ex-Aid. He is a surgeon of Seito University Hospital, considered by many to be a genius in his profession, and the son of Haima Kagami.

History
While the details are unclear, Hiiro holds a grudge against Taiga Hanaya, whom he claims took something important from him.

Hiiro was working for a prestigious hospital in the United States before being called back by his father to handle the Bugster outbreak. Given the Gamer Driver and the Taddle Quest Gashat, he had just arrived in Japan when a second candidate, pediatrics intern Emu Hojo, had been chosen to join the CR as Kamen Rider Ex-Aid.

Hiiro appeared in CR after Emu receives his special Stethoscope. He wasted no time in alienating and belittling Emu, seeing the latter's presence as a "No thank you". He arrived with two of his nurses to the location of Rensuke Natori, the next Bugster patient. Transforming into Brave Level 1, he extracted the Aranbura Bugster from Rensuke. However, before he could continue as Level 2, Brave and Ex-Aid were attacked by a black Ex-Aid, allowing the Bugster to escape.

Still frustrated about being interrupted, he asked Asuna to alert him when the Bugster reappeared. He proceeded to eat cake, seeing that as more important than helping the patient, infuriating Emu. Hiiro found Emu later when Aranbura had taken Rensuke's fiancé Asami hostage. Ignoring Emu's warnings (and calling him a failure of a doctor for letting the well-being of his patient get in the way of fighting the Bugster), Hiiro transformed into Brave Level 2, and attacked Aranbura using a sword generated in the game map, which later turned into the Gashacon Sword. Brave and Ex-Aid fought the Bugster together, although Brave was the one to deliver the final blow on Aranbura using Taddle Critical Finish (Ex-Aid attempted to finish the Bugster using Mighty Critical Finish).

Nevertheless, the incident would push Emu to stay in the CR, not trusting Hiiro with patients due to his apathetic nature.

Hiiro was disgusted to learn that Taiga Hanaya had gotten a Gamer Driver and Bang Bang Shooting Gashat, becoming Kamen Rider Snipe. Finding Snipe and Ex-Aid fighting the Revolve Bugster, he transformed into Brave and attacked Snipe in order to take the latter's Gashat & Gamer Driver. The two fought briefly before Ex-Aid reminded them of the bigger priority. However, Revolve was able to lower Ex-Aid and Brave's health meters to critical levels. Brave decide to cancel his transformation, deeming it too risky to fight. However, Ex-Aid bravely fought Revolve & defeat him (Which actually turned to be a clone) using Mighty Critical Finish. Snipe finished off the real Revolve using Bang Bang Critical Finish. After Taiga confiscated Emu's Gashat, Hiiro said that Emu reaped what he had sowed and that's what Emu will get if he operates with high risk. Much to his confusion, Emu seemed unbothered, as Yuki had been saved.

Hiiro and Poppi confronted Kuroto when the latter went to CR to apologize for underestimating Taiga. Hiiro requested one of each kind of Gashat. His request was denied, as only one of each Gashat existed, but he was assured that more Gashats would be ready in a few days. The conversation was interrupted by Emu, who requested Hiiro's help in helping Yoshitaka Nishiwaki, the newest Bugster victim. Hiiro learned of the fourth Rider, coroner Kiriya Kujo, Kamen Rider Lazer. Hiiro observed Lazer and Snipe take on the Bugster after it emerged from Nishiwaki, but joined the fight after the Motors Bugster was separated, primarily to keep Snipe from finishing it off. His duel with Snipe was interrupted by the black Ex-Aid. Both riders were brought to their knees by the black Ex-Aid, only for the intruder to disappear without a trace. Weakened by the ambush, Hiiro could only watch in frustration as Taiga walked away.

Sometime later, Hiiro and Poppi were alerted by Kuroto to the theft of the four new Gashats.

Personality
Hiiro is intelligent and capable, yet cold and arrogant. He is only concerned with the success of the operation, and opposes personal involvement with his patients. As a result, he looks down on Emu, deeming him unworthy due to his inexperience and conflicting ideals. However, his animosity with Emu is nothing compared to his hatred for Taiga Hanaya. He is the only one to question Kuroto's somewhat dubious behavior, showing some level of perceptiveness. Hiiro has a liking for desserts, mainly cake or pie, which he claims is to increase his energy in between operations.

Hiiro treats his fighting with Bugster as an operation. He has a habitual quirk of raising his hands in the position most surgeons use when they are about to operate on a patient, and refers to the Gashacon Sword as his "scalpel". He often also speaks in a mannerism akin to his civilian job after transforming. (Ex. "Commencing Bugster removal operation"). He will cancel his transformation if he deems the situation too risky (primarily when his Rider Gauge is almost depleted). Whenever he encounters someone he doesn't like or doesn't feel belongs in the situation, he will refer to their presence as a "no thank you".
