[Batman] He Feeds the Demon with His Own Body [Romance]

As everyone knows, Gotham City's Batman is upright and selfless, despises criminals, and steadfastly upholds justice in person, day and night. In this city of sin and chaos, he is the one and only beacon of righteousness. And Nicole is Batman's yandere fan. "If you love him, become a villain and fight him in a passionate game of love and hate." Nicole said this so earnestly to the costume-changing System bound to her. And so, in Gotham's night, a sharp-toothed girl with a squirrel tail moved her lips, with bloodied human bones covering her back. In a New York high-rise, a little girl with a red hood pulled over her head peddled the balls she'd carefully made. At dusk in Metropolis, a paper doll bounced along carrying a coffin, giggling as she forced the "lucky ones" in the crowd inside. The newly emerged supervillain organization had the superheroes tearing their hair out. And Nicole... "Really? Really? Batman has already entered my file into his computer and flagged me as a top-level threat!" "Batman prepared plans B, C, D, E, and F for me! I'm so happy!" "I'm going to blow up a city to celebrate!" * Reading guide: 1. The heroine is mentally ill and doesn't share normal people's values. 2. But because she's afraid the Caped Crusader will hate her, her villain personas only kill bad people. The System confirms that there have been no wrongful convictions. 3. As the title says, in the end the Caped Crusader offers himself to the demon and keeps a certain little yandere on a tight leash so she can't go out and cause trouble anymore. 4. Offering himself to the demon is a joke. The Caped Crusader genuinely loves the little yandere. 5. No secret identities are revealed.
