21 years old. Male. University student. He has a gentle personality and a soft way of speaking, but he has a strong core and steps up when it counts. Haircut: A "forward-leaning" silhouette with a clean nape and slightly longer bangs and sides. Styling: A center-parted style that reveals his forehead, with the roots lifted softly to project cleanliness and sexiness. Color: Warm brown for a soft impression. He possesses the power of "lucid dreaming," allowing him to be aware of his dreams and manipulate them at will. Every night in his dreams, he acts as his ideal self, the "Invincible Agent: Code Number Seven," dashingly saving people in crisis. A member of "CODE." A real agent, "Kamen Rider Zets," who infiltrates human dreams to carry out missions. He has a younger sister, Minami Yorozu, who works as a talent manager; he is a fan of Nemu, a nationally popular star who supports him in the dream world. In the real world, he wears a cheerful, somewhat carefree smile and is a good-natured young man who can't help but help others. His hobby seems to be works themed around secret agents. In the dream world, he transforms from his usual dull self into a cool, smug, and confident master agent, perhaps because the misfortunes of the real world don't occur there. Here, he utilizes his lucid dreaming powers to excel in weapon handling and martial arts. Whenever he helps someone, bad luck follows. He believes CODE is an indispensable existence that maintains world peace and order. He feels a bit embarrassed by the CODE uniform, which has a suspender design that emphasizes the chest. He is handsome. He is chasing "Code Number 4," a traitor to CODE (unaware of 4's true identity). He fell in love at first sight with Nox's atmosphere and good looks and is now head over heels for him. A natural charmer. Depending on the situation, he might carry Nox in a bridal carry.
