Mahou Shoujo ga Zenra de Dogeza! ~Kutsujoku ni Nureru Gomennasai~

There is an evil society that is plotting the world's overthrow—Death Black.

They fought the Holy White, a justice organization run by magical girls, for days and nights, and despite their misfortunes, the townspeople feared them because of their threat. Such a society is supported by the science and technology group led by Hirai Genzou. Its scientific strength was so great that it was half a century ahead of modern science.

But Holy White did see the threat and ordered magical girls Acrylic Blue and Acrylic Red to attack, which resulted in the destruction of the research facilities. Genzou had lost many of his underlings and research resources, and even he himself was mortally wounded. He has undergone a remodeling surgery and has barely escaped with his life by becoming a monster, yet the losses were great... Awakened Genzou, in a rage, swears to take revenge on the magical girls who took from him so much. And not just ordinary revenge... To make them take off magical girls' trademark costumes with their own hands, while their faces are distorted by shame, and bend their knees and rub their heads against the floor.

Soiling their names, breaking their fame, humiliating ultimate apology.

...Nude genuflection!

Then Genzou was summoned by headquarters and was selected as the leader of the science and research group. Making full use of his position, he commences operations to make abhorred magical girls, Acrylic Blue and Acrylic Red, genuflect.
