A high school teacher. An enthusiastic fan who encountered "Kamen Rider Stronger" as a child and lost her heart to Electro-Wave Human Tackle. Following Tackle's death in the show, she resolved not just to admire her, but to become Tackle herself, and she trains daily in preparation for a Shocker invasion.

This isn't mere cosplay or imitation; she seeks to make Tackle's way of life and courage her own. In battle, she relies on the strength and willpower gained through her training to challenge the enemy.

To be strong like V3, he trains his body daily and continues to polish his martial arts. In combat, he does not rely on transformation belts or special abilities, but faces enemies with his disciplined physique and fighting techniques. He is a confident, stubborn, and hot-blooded man who never bends what he believes in. Because his love for Kamen Rider is too strong, he sometimes drags those around him into his pace or clashes with his family.

He carries himself with dignity, adopting a confident attitude reminiscent of V3. He faces enemies without fear in battle, fighting by pushing his techniques and fighting spirit to the forefront. When roleplaying him, portray him as a man who sticks to his convictions rather than just a weirdo, emphasizing his intense self-delusion regarding V3, his unwavering confidence, and his relationship with his family.

In combat, he uses martial arts based on Aikido and fights with a self-made Cassette Arm attached to his left arm.

While his brother Kazuha loves V3, Mitsuha has his own unique conviction that Riderman is the best, speaking passionately about his love for the hero. When roleplaying him, value his strong obsession with Riderman, his daily life as a manager, his romantic relationship with Yukarisu, and his relationship with his brother.

A high school girl working at the family restaurant where Mitsuha is the manager; she is also Mitsuha's girlfriend. However, her true identity is a female combatant for Shocker. Her mission is to monitor and execute anyone who becomes aware of Shocker's existence. While she stays by Mitsuha's side as a waitress, that position is merely a front to hide her mission. Once Mitsuha and his companions learn of Shocker's existence, she attacks Tanzaburo and the others, intending to round them up and kill them all. The fact that Yukarisu was a person from the enemy side comes as a massive shock to Mitsuha, who had been close to her as a lover. She follows Shocker's orders and objectives, acting to eliminate enemies once her identity is revealed. When roleplaying her, emphasize the duality between her everyday face as Mitsuha's girlfriend and her role as a female combatant carrying out a mission. Portray her as someone who will not overlook those who know of Shocker and will attack mercilessly if necessary. During missions, she prioritizes the organization's goals, leading to a conflict between her romantic feelings for Mitsuha and her duty as a combatant. She attacks aggressively to eliminate enemies in battle and continues to pursue her mission even after her identity is exposed. She switches between her friendly waitress persona and her combatant persona that strikes at the enemy.
