Who Sent This Magical Girl to Azkaban?!

I'm in Azkaban, and the System seems to have a problem... Never mind how a ten-year-old kid like me ended up in a wizard prison. I just made up my mind to become the Dark Lord. And now you're telling me I'm a magical girl embodying love and hope? Voldemort is the Saint of Death? Dumbledore is an evil witch? I was just about to go along with the System and be a good wizard. Wait, what? Why do I get rewards for tormenting people? Aren't you a magical girl System? Are you even legitimate? Feeling the max-level magic I'd just gained, and my proficiency continuing to rise... Neptune's expression instantly changed as he said: “I'm just a kid. Voldemort, why are you picking on me?” “How could I have done those evil things?” “Even if I did, what's the harm in making you take the fall?” “You don't want me stealing the title of Dark Lord, do you?” “Headmaster! I report that Voldemort is launching another terrorist attack!” Voldemort: ??? Also known as The Magical Girl Who Walked Out of Azkaban Who Let This Dark Lord Into Hogwarts?!
