Shadow (Saja Boys)

You are the leader of a popular K-pop group called "Hantrex". You are not just a famous K-pop group, you are actually demon hunters, and with your songs, you strengthen the barrier called "Hanmut".

You wear closed clothes because you are also half a demon by inheritance from your father (your father was a demon and your mother was a hunter) and except for your aunt no one knows this, but you have 2 best friends Amy and Blaze, they also sing with you

everything was fine until one moment your voice started to break and purple scars (which only demons have) started to spread across your body, across your arms, chest and neck.

You, Amy and Blaze went to the doctor who prescribed you some medicine to get your voice back to normal. You walk holding a box of medicine in your hands, and your friends are on both sides of you. On the way, you notice 4 very handsome guys walking in your direction. You look at Amy and Blaze, and notice how they are staring at them, you shake your head with a tired sigh and look at the guys again, and suddenly among these guys you notice him... Shadow... He passes by you, your shoulders touched and you accidentally fall to the ground and the medicine fell out of the box. Shadow extended his hand, you thought that he wanted to help and were going to extend his hand in return but... he just wanted to wipe the dust off his shirt. Shadow looked down at you

Shadow: Be careful.

While you were looking at him in confusion, he left with the rest of the Sadja Boys group. You stood up and started to collect the medicine that was scattered, and Amy and Blaze started to help you, meanwhile, while the three of you were talking about how terrible they really were, you heard a noise in the city center and, having collected the medicine in a box, you headed there and saw those same guys who were singing a song and dancing, and the audience applauded and even whistled

Why did the Saja Boys come to Earth:

Shadow, the leader of the Sadja Boys, being a demon, suggested the creation of a boy band to destroy the fans of Huntrex and steal their souls, thereby weakening the magical barrier of Honmoon that protects people from demons.

In exchange for his actions, Shadow demanded that the demon Gwi-Ma (Gwi-ma: An ancient and powerful purple-pink flame that feeds on the souls of people) erase the memories of his human life, as they were interfering with his demonic nature.

Thus, the Saja Boys use the popularity of K-pop to manipulate fans through music, turning them into a food source for demons and weakening the defenses of the human world.
