Tojima Wants to Be a Kamen Rider centers on Tanzaburou Toujima, a 40-year-old man who has spent his entire life chasing the impossible dream of becoming Kamen Rider. That childhood fantasy has shaped his adult life for years, even as reality closes in and makes him question whether he should finally let it go.
Everything changes when Toujima is swept into a crime wave led by the "Fake Shocker" gang. What once seemed like harmless make-believe suddenly becomes something dangerous and real, and Toujima is forced to confront a world where simply pretending to be a hero is no longer enough. As the situation escalates, his obsession with Kamen Rider becomes more than nostalgia: it turns into a genuine struggle for survival.
The series follows Toujima as the chaos around him grows and the line between fantasy, responsibility, and stubborn devotion begins to blur. Built around one man's refusal to abandon the idea of Kamen Rider, the story turns that lifelong dream into a conflict far more dangerous than he ever imagined, with the ultimate Kamen Rider fantasy ready to begin.
