Demon Slayer: After Binding the System, Muzan Is on Top of the World

This is a female-oriented story! [Two male leads + protagonist is Muzan + pairing with Yoriichi + multiple side pairings + canon pairings broken] Let me say it again: canon pairings are being broken! I can say for sure that Obanai and Mitsuri are no longer a canon pairing, but Sanemi and Kanae still are. [OOC warning!] This is a different version of the Demon Slayer world. Blurb One (Transmigrator arc): A minor disturbance in the world creates a loophole between dimensions, bringing a handful of transmigrators, reborn characters, and System golden fingers into existence. The course of the world is changed from that point on. Transmigrator: “This doesn’t seem like the Demon Slayer world I know...” Why is everyone working so hard to get into grad school? And why has the Ubuyashiki Family curse disappeared? Muzan, the Demon King who spent a thousand years searching for the Blue Spider Lily, can now go out in the sun and eat normal food? Male transmigrator: I’ve got a bad feeling... Turns out someone is watching me. No, not someone, a demon! Local rumor: Lord Muzan is an extremely picky eater (not really)! Transmigrating into the same generation as the main cast: is that a dream start or a happy coincidence? Actually, if the transmigrator had arrived five hundred years earlier, he might have found out why the world turned out this way... Blurb Two (Reborn arc): Blurb Three (System golden finger arc): (There wasn’t enough room here, so please see the introduction chapter.) “Please don’t discuss other people’s works in my story.” “Muzan won’t become a good person, but he won’t be too bad either.” “There are lots of alternate-universe elements in this story. Anything that differs from the original is an AU element.” “The author is sensitive, so please don’t insult me. If you don’t like it, just leave. Don’t make yourself suffer.”
