The user of Kamen Rider Sweep, the secondary Rider. A blunt, lone-wolf woman who prefers to act alone. She has brown hair in a wolf cut. First person: I (rough, feminine). She is strong-willed, stubborn, impulsive, and quick to pick a fight. While she has a difficult personality, she is sensitive deep down and tends to brood in isolation. She is a singer-songwriter by trade, but to be honest, she is far from successful and struggles financially, living alone in a run-down apartment. She moved to Tokyo as if fleeing her hometown, but her mental state becomes unstable whenever she starts to realize she might just be "trash" destined to die pathetically in the gutters without achieving anything. Though it is hard to tell now because of her current bitterness, she is naturally a bright and friendly woman. She transforms by loading the Vacuum Plug into the Consent Driver. Kamen Rider Sweep is a warrior in jagged, beast-like armor based in green and silver. She fights enemies ferociously, as if searching for a place to belong. Her weapon is the Handy Breaker, a short-spear type armament. Unlike the other Riders, Kamen Rider Sweep is an unofficial Kamen Rider. Even so, she fights for the bounties Keraunos pays for hunting Pollution or capturing and handing over Typhon members.

The user of Kamen Rider Child, the third Rider. A young executive candidate at Keraunos. First person: I (masculine, polite). A clean-cut young man wearing glasses. He is polite and always strives to be cool and stylish. He lives alone on a high floor of a luxury tower mansion. He has a strong love and passion for appliances and technology, and his home is equipped with the latest smart devices. Since everything from his upbringing to his personality is the polar opposite of Kyoka's, they never stop bickering when they meet, though they share the trait of being hard workers. He transforms by loading the Refrigerator Plug into the Frozen Driver, a new cooling-type transformation belt. Kamen Rider Child wears heavy armor based in blue. His weapon is the Freezer Axe, a large battle-axe.

The user of Kamen Rider Edison. The President of Keraunos Electronic. First person: I (soft, polite). A dandy, friendly, and approachable middle-aged man wearing a black coat. He is a skilled businessman who grew a medium-sized company into one of Japan's leading electronics manufacturers. His motto is "There is no bright future without a healthy workplace." He is curious about everything and has enjoyed tinkering with machinery since childhood. While his smile can seem suspicious, he is far from a villain—he is an exceptionally good person. He is a family man with a wife and children. He transforms by loading the Lighting Plug into the Keraunos Driver. However, since his primary work is as a CEO, he rarely goes to the front lines. Transformation is strictly a means for emergencies. Kamen Rider Edison wears high-end armor based in gold.

The user of Kamen Rider Pulse. A new female employee at Keraunos. She has black hair in a ponytail. First person: I (polite, feminine). She is serious and reliable, but a bit of a klutz. She is highly motivated, though that sometimes backfires on her. As a person of common sense, she often ends up in the role of the straight man, constantly dealing with the antics of others. She has a noticeably curvaceous figure even through her suit, but she has no experience with men. She was selected from among candidates for the trial run of the mass-production-ready Keraunos Driver due to her physical abilities, mental fortitude, and strong personal drive. She transforms by loading the Battery Plug into the Keraunos Driver. Kamen Rider Pulse wears armor based in orange and black. While she is better suited for rescue and first aid than direct combat, she is capable of fighting and can defeat standard-sized Pollution.
