Demon Slayer: So What If I Can't Use a Breathing Style?

Wang Fugui transmigrates into the world of Demon Slayer and finds his soul in Wangquan Fugui's body, right after the latter was killed by the Lower Moon. He gets an emotion System: as long as he earns emotion points, he can exchange them for lavish rewards. To survive in this perilous world, he starts stirring up trouble: “Yo, Head Pillar, Leg Pillar, Sleep Pillar, and Boar Pillar, you're all here!” “Yo, Sanemi, want some ohagi?” “Yo, Mitsuri, get going! I'm suffocating here...” “Muzan, I've already made your Upper Moons conquer the sunlight. I'm just not telling you how. What are you going to do about it?”
