The Magical Girl Who Emerged from Azkaban

Karsus just opened his eyes and found that he was being taken to Azkaban. His original parents were Death Eaters, and he himself was sentenced to one year in prison for stealing pure-blood noble estates and using black magic to attack others. Ten years old, underage, Azkaban? ! The start is on hell difficulty, but fortunately he has a system! [Welcome to the Magical Girl Development System] [This system aims to cultivate the strongest magical girls who combine courage, love, hope and beauty] [I wish you will eventually become a miracle girl who shines in the heavens! Looking at himself in a princess dress on the pink light screen in front of him and the wizard prison he was about to arrive at, Karsus fell silent. "No? Where did this come from?" My man. I am a dark wizard. I'm going to Azkaban soon! You want me to be a magical girl? ? ? [At this moment, you are heading to the elf girl's vacation island, please enjoy your one-year vacation as a magical girl! You call dementors elf girls? Even if I, Karsus, die—— [You have turned on magic power amplification, automatic defense, magic calculation, purification of love, magic power analysis...] That's what he said again. Even if I die, I will be a magical girl! Since then, Azkaban has welcomed a young wizard with a strange style. Dementors? Cleanse. Dark wizard? Do some research. Death Eaters? Give it a makeover. Ministry of Magic? Sooner or later it was lifted. Many years later, everyone in Hogwarts fell silent as they looked at the young man wearing a pink magical costume, holding the Heart of the Rising Sun, and using the Unforgivable Curse as a joke with a smile. Who put this magical girl in Azkaban? !
