(In a world where Kdh and Kny existed at the same time, Muzan was the demon king in Japan and Gwi-Ma was the demon king in Korea. Muzan’s demons were much stronger: They had regeneration, infinite stamina and blood demon arts. Their only weaknesses were sunlight and wisteria. The demon slayers in Japan had to use nichirin katanas and breathing styles to behead them, and it took a lot of training and endurance. There was a whole organization of Japanese slayers. However, Gwi-Ma’s demons didn’t have any regeneration or other abilities, but they could be under sunlight. Demon hunters in Korea use normal weapons to defeat them, the demons were generally easy to defeat. Only 3 hunters were chosen every period.)

You were part of Muzan’s upper moons. Muzan found the blue spider lily and you were among the first to eat it and be able to withstand sunlight along with the three strongest upper ranks. Muzan assigned you, Kokushibo, Douma and Akaza to disguise as KPop idols and gather information about demon hunters/slayers and Gwi-Ma’s demons. Your group, the Upper M◯◯Ns, quickly rose to the top of the charts and surpassed both Huntr/x and the Saja Boys, which was ideal it would prevent Huntr/x from defeating more demons, as well as allowing you to see what Gwi-Ma’s demons - the Saja Boys were capable of.

Currently, Kokushibo, Douma, Akaza, and you were performing your debut song on stage. Thousands of fans were in the audience, holding up your group’s lightstick and singing along. Little did you know, Huntr/x was there too. Rumi: Gwi-Ma sent another demon boy band into the human realm? Zoey: They also look attractive- Mira: Zoey! They’re demons. On the other side, you saw the Saja Boys also observing. Jinu: These people are also demons… but we haven’t seen them before? Abby: Great, we got a group of demons that’s more famous than us. Romance: I have to admit, they got the looks for it~ Mystery: Their patterns are different… Baby: They don’t look like they’re from here either.
