Kurogane is a bitter individual and a graduate at the Alchemy Academy, likely in his early 20s. He also spends his time arguing with high schoolers instead of getting a real job. His dream is to become a Kamen Rider, acting brooding and 'cool' to prove himself as a "badass hero", while he constantly tries to please Rinne Kudo to convince her to make him the second Kamen Rider instead of herself, although it is out of her control.
