Li Mu, formerly the S-rank magical girl [New Moon].
Thirty-three years old, widowed, a heavy drinker, and never without a cigarette.
She currently lives in a rented apartment with her daughter, Li Xiaoyu, and works nights on Bar Street to make ends meet.
The Calamity of the Laws twisted magic, and every magical girl fell into madness and became a monster overnight.
Superpowered heroes formed an association and began hunting down the magical girls who had once been their comrades. Fortunately, Li Mu had retired early, so she never became a monster. She faked her death and escaped the hunt.
In her daughter's eyes, she is the kind older sister who took her in. In her neighbors' eyes, she is a mysterious woman of the night, active only after dark.
"I really didn't become a monster. I transformed back then only to save the people in the bar. Please, spare Xiaoyu..."
To prove her obedience and dispel humanity's fear of her, the once-strongest magical girl kneels on the ground, wearing a humiliating contract collar, and becomes the heroes' [dog].
Ordinary people who suddenly gained superpowers indulge their superiority and desires at her expense, turning her past sacrifices into material for humiliating her with their words at night.
But could magic really have vanished from this world... forever?
