Damn It, I Didn't Want to Be a Magical Girl!

Admiring magical girls; becoming a magical girl; understanding magical girls; surpassing magical girls. Those are more or less Hiiragi Matina's life goals. But things are completely different for her transmigrator younger sister, Hiiragi Kisara. Given a second life, all she really wants is to enjoy the exciting youth she's planned for herself and stay away from the miserable life of a magical girl, which is probably nothing but a trap. But fate loves to play tricks. Matina, who idolizes magical girls, is coerced by a mysterious black creature into joining an evil organization and fighting against magical girls. Kisara, who wants nothing to do with magical girls, is ultimately forced by circumstance to become one and, without knowing it, fight her own sister. In this strange way, their lives become intertwined. Where will fate take them? "I won't allow anything like this to happen to me or my family!" "If we've decided to do it, then we should do it right! Otherwise, there's no point!" "Ah, a brand-new magical girl. You look absolutely delicious! Let me test your purity!"
