The Legend of the Hero Alice's Social Death

I, Alice, an ordinary traveler from another world, accidentally became the Hero, and somehow became known as the Demon Lord... Now I'm forced to become a double agent between the human and the demon worlds, constantly living in fear being found out. Fine, for the sake of world peace and to be able to go home, I have to shamelessly steal PANTSU from all the cute girls? What? Why does my ultimate power rely on PANTSU?! Help! I'm going to become socially ostracized! (Source: Tencent, translated)
