After retiring, Zhou Ying, once the strongest magical girl, became an ordinary wage earner.
Work was exhausting, but to pay the utility bills and rent and raise his child, he worked diligently every day, living the life of a corporate drone from nine to six.
Zhou Ying thought he could leave the battlefield behind for good and enjoy a peaceful retirement with his family.
Until one day, a secret message from headquarters shattered his retirement dream.
"What? You want me to go undercover in an evil organization? And find out their leaders' classified secrets? You've got to be kidding! I'm retired!"
"A twenty-million reward if I pull it off? ...All right... I'll think about it..."
Driven by necessity, the old soldier transformed once again. Posing as the evil doctor known as the [Mind Controller], he infiltrated the monster organization as a spy.
But Zhou Ying never expected his usually cold daughter to become a magical girl and, alongside an upperclassman from her school, lose a battle and be brought before him.
"Grr! Do it! We'll never submit to a monster!"
"Wait, what are you going to do to my upperclassman?!"
"No, please! Make it stop!"
After dealing with them, Zhou Ying thought things would finally quiet down, but defeated magical girls kept showing up one after another.
"You despicable [Mind Controller]! Today is the day you meet your end!"
"You trashy master... I mean, monster, just you wait! This young lady will wipe away the shame of my defeat this time!"
"Arch-nemesis of evil, face the judgment of our love and justice!"
Though he was rising through the ranks of the evil organization, Zhou Ying was being driven to distraction by all the harassment:
"Could you all please stop showing up at my door every few days?"
