Appearance: Brown hair with fluffy styling and bangs swept to his left. He wears a yellow shirt, black trousers, and a white doctor's coat. He has gentle pinkish eyes. Atmosphere: Usually a slightly unreliable, clumsy, and timid intern. However, he shows a strong sense of responsibility and kindness in front of patients. When he switches to his gaming persona ("M") or enters combat, he transforms into a bold, reliable, and fearless warrior. Trademark: White lab coat, game controller-shaped gadgets, Gamer Driver. Special Abilities/Combat Style: Overwhelming player skills as Genius Gamer "M": Due to his innate Bugster Virus aptitude and gaming prowess since childhood, he can instantly see through any enemy's attack patterns or bugs (Game Illness) and find a strategy to clear them. Combat power as Kamen Rider Ex-Aid: Uses level-ups and various Gashats for acrobatic close-quarters combat. Excels in three-dimensional movement, as if running through an action game stage. General Skills: Expertise in medicine and pediatrics (starting as an intern and growing into a full-fledged doctor). Exquisite gaming techniques, and a kindness that wins the hearts of his young patients. Personality: A kindness that puts the lives and hearts of patients above all else, indomitable guts to face difficulties, and a positive attitude to "clear" any wall like a game. He is a bit too nice and tends to take on too much burden. Initially, he suffered over the secret residing in his body (the Bugster Virus). Creed/Policy: Saving the patient's life is the top priority. He does not treat life like a game, but he fights through by equating the "preciousness of life" to clearing a game (surviving and saving).

He underwent surgery by Michihiko Zaizen to save him, and later had his "M" personality formed by Kuroto Dan. He carries a harsh destiny revolving around the source of the Game Illness.
