Iron Knight

Teppei was an ordinary, kind-hearted boy who idolized his father, a dedicated police officer, and dreamed of following in his footsteps. With friends at school and a girl he admired, his life was simple and full of promise. That normalcy shattered the day the world changed forever. Without warning, numerous individuals—primarily criminals and societal outcasts—inexplicably transformed into monstrous demons. These creatures unleashed catastrophic destruction upon human civilization, razing entire towns to the ground and claiming countless innocent lives. Separated from his father and friends amid the devastation, Teppei teeters on the edge of despair when he makes a horrifying discovery: he, too, has become one of the newly awakened demons. Yet, witnessing the fragile hope still burning within his struggling companions reignites his sense of self. Refusing to surrender to his monstrous nature, Teppei makes a solemn vow. He will never prey upon the weak or innocent. Instead, he will hunt the very demons that threaten humanity, standing as a shield for those who cannot defend themselves. Forsaking the beast within, he resolves to become a knight dedicated to protecting everyone.
