[Crossover] What Could Yokai Possibly Do Wrong?

Many years later, Qianshou Hongye finally understood that being a monster meant you really couldn't have any wicked ideas. As a frail, pitiful maple tree demon, the first time she had a wicked idea, she set her sights on the Four Souls Jewel worn by a strangely dressed priestess. She was just thinking about how to get her hands on that huge piece of the Four Souls Jewel when, before she could even get close, a half-demon with dog ears spotted her, slashed her, and kicked her into a well. For some reason, she ended up as a baby in a human woman's belly. The second time she had a wicked idea, she heard from a white-haired ninja, a deputy leader of the Hidden Leaf Village who had become her older brother because she was now human, that her eldest brother had fought a battle to the death with his old friend, who had left the village long ago, and had ultimately won. Hongye thought that her eldest brother's old friend came from such a clever family, and wondered if he might be faking his death. But the moment she stepped into the morgue, she was caught by that very man, who was, in fact, still alive. Her frail human body couldn't take much, and she died in no time. The last time she had a wicked idea was after she arrived in yet another strange place and became human again. She decided to seek out the nearby creature she'd heard about, one that only came out at night, couldn't be killed even if its limbs were cut off, and supposedly ate people. It sounded a lot like a monster, so she wanted to ask if it knew how to turn her back into one. In the end, she earnestly tore off the head of the demon in front of her, who was yelling that he would eat her and her teammates, and earnestly taught him a lesson. Monsters mustn't have wicked ideas. Theme: The hero defeats the dragon.
