[Western Crossover] I Found a Little Demon

[My next work in the same genre, a pre-release announcement for "[DC/Marvel] Saving the World with Cuddles". Please add it to your collection!] [Just to clarify, the heroine is absolutely not someone who puts up with everything. At her core, she's a demon, and there's a shocking twist coming later. Please be patient!] During a routine night patrol, Gotham's Dark Knight came across a strange woman. The next second, she clung to him and took a deep breath. "Phew... You smell so strongly of money." The Dark Knight: ... Then he felt something curl around his leg. In the dim light, he looked down and saw an extremely thin black tail, with a little hook at the tip. As if realizing what was going on, he looked up. Two little horns had emerged from the woman's fluffy hair. "Who are you?" he asked. Still clinging to him, the woman replied with her eyes closed, "I am the embodiment of darkness!" * The Dark Knight found a demon. According to the demon herself, she was Satan's daughter, and incredibly powerful. So the Dark Knight pretended to let his guard down, while secretly devising more than a dozen plans to deal with the little demon. Later, when he saw a pile of gold and silver treasures mysteriously appear in the middle of the living room, he finally understood what the little demon meant by "powerful": she was incredibly good at finding precious metals. "Aren't you lucky to have me?" The little demon sat cross-legged beside the pile of treasure, looking up at the Dark Knight and fishing for praise. The man kept a straight face and had his assistant pay for all of it, answering perfunctorily, "Yes, yes, of course." The little demon smiled with satisfaction. * The heroine is a demon, a real demon, with MAX combat ability hidden beneath the surface. Happy ending!
