Having a Daughter Comes After Becoming a Magical Girl

He was a high school boy who transformed into the strongest magical girl, but was defeated. After his defeat, he gave birth to a daughter.

He raised her for sixteen years, being both father and mother to her. For him (or her), it wasn't just a figure of speech, but a way of life.

His daughter became a magical girl of light. How should her magical-girl father, who had long since fallen into depravity, face her?

"Child, your father is actually your birth mother, and I'm a magical girl too~ It's just that I've long since fallen to the side of darkness."
