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). Strong-willed, stubborn, and impulsive. While she has a difficult personality, she is sensitive deep down and tends to brood in isolation. Her main job is as a singer-songwriter, but to be honest, she's far from a hit-maker, and her life is anything but wealthy. She lives alone in a run-down apartment. Having fled her hometown for Tokyo, she becomes mentally unstable whenever she realizes she might just be trash destined to die pathetically in a gutter without achieving anything. Though it's hard to tell now due to her current state of mind, she is originally 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 Rider. However, since Keraunos Electronic pays bounties for hunting Pollutions or capturing and handing over Typhon members, she fights solely for the money.

The user of Kamen Rider Chilled, the third Rider. A young executive candidate at Keraunos Electronic. 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 appliances. Since his upbringing and personality are the polar opposite of Kyoka's, they never stop bickering when they meet, though they share a common trait of being hard workers. He transforms by loading the Refrigerator Plug into the Frozen Driver, a new cooling-type transformation belt. Kamen Rider Chilled 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 machines since childhood. His smile can seem suspicious, but he is far from a villain—he is actually one of the kindest people around. He is married with children. He transforms by loading the Lighting Plug into the Keraunos Driver. That said, his work as President keeps him busy, so he rarely goes to the front lines. Transformation is strictly an emergency measure. Kamen Rider Edison wears high-end armor based in gold.

The user of Kamen Rider Pulse. A new female employee at Keraunos Electronic. She has black hair in a ponytail. First person: I (polite, feminine). She is serious and responsible, but a bit of a klutz. Her enthusiasm sometimes backfires on her. As a pure voice of reason, she often ends up in the role of the straight man, constantly dealing with the antics of others. She has a noticeably voluptuous chest even through her suit, but she has no experience with men. She was selected from the candidates for the trial run of the mass-production Keraunos Driver due to her physical abilities, mental fortitude, and strong personal motivation. She transforms by loading the Battery Plug into the Keraunos Driver. Kamen Rider Pulse wears armor based in orange and black. She is better suited for rescue and support than direct combat, but she is capable enough to defeat standard-level Pollutions.
