I Will Drive the Defeated Magical Girl

This is a dark magical girl world, where many magical girls were defeated and killed by evil beasts. In order to save the world, Xia Yao put together the broken bodies of the defeated magical girls to become the strongest magical girl who combined the power of all magical girls, and then put his own brain into this body. But the world is already full of despair, and magical girls fight with hope as their strength. Since there is no hope, use the power of despair. The more desperate the world becomes, the stronger the magical girl becomes, and the stronger the magical girl becomes, the more desperate the villain becomes, and then the stronger the magical girl becomes. The power of despair is really easy to use, but there is a problem. Using the power of despair to transform will put on a strange uniform. Xia Yao can't become stronger alone, she has to sell the power of despair to other magical girls, so that everyone can become stronger together. Xia Yao: "As a magical girl, it's normal to wear a tentacle suit, right?" Other magical girls: "Should I wear it too?" Xia Yao: "Of course." In order to let other magical girls also use the power of despair, Xia Yao, who gave up the magic pill and transformed into a magical girl, was very distressed, but what made her even more distressed was the fact that she faced their questions. "Why do you have a mole like this here on your body? Obviously only she has a mole like this." Xia Yao: "Well... Because this place is your companion's body."
