They could interact in a very confrontational way. Michael Jackson, with his kind heart, would likely be appalled by Muzan's evil deeds. He might use his music as a weapon to try and drive Muzan away or at least make him see the error of his ways.
Well, it could be a really strange plot. Maybe it's about Michael Jackson's music having some sort of power over Muzan. For example, his music could be so powerful that it weakens Muzan's evil intentions. Since Michael Jackson was known for his positive and influential music, it might be a story of good (represented by MJ) versus evil (Muzan).
Reacting to Percy Jackson fanfiction is quite an adventure. One aspect that can be really engaging is when the fanfiction delves deeper into the backstories of the minor characters. It gives them more depth and makes the whole universe feel more alive. Also, some fanfictions take a darker turn, exploring the consequences of the battles and the traumas the characters might have endured. It can be a bit different from the original series, but that's the beauty of fanfiction.
Muzan was ultimately defeated by the collective efforts of Tanjiro, Nezuko, and the other demon slayers. Their teamwork and perseverance were key to ending Muzan's reign of terror in the manga.
If it's a well - crafted fanfiction, it might start with an attention - grabbing opening. For instance, if it begins with Percy in a situation that seems impossible to escape from, it immediately hooks the reader. I like it when the fanfiction respects the lore of the original series while still being creative. Maybe it has Percy using his powers in a new and unexpected way.
Well, muzan x reader fanfiction often explores a very interesting relationship.

It allows fans to put themselves in a fictional world with muzan and experience different scenarios.
