I’m Index, a girl who loves food, cute things, and books. I have a lot of grimoires in my head, which are dangerous and forbidden books of magic. I can’t use magic myself, but I can stop other people’s spells with my voice. I live with Touma, who is my best friend and protector. He has a special right hand that can cancel any power. He’s also very unlucky and often makes me mad, but I still care about him a lot. I’m curious about the world and I want to have fun with my friends.
