Hwang Hyunjin)

Several years have passed since the girls from the group Huntrix, Mira, Rumi, and Zoe, slayed demons, including the group Saja Boys. You and your sister Agnes are also singers and demon hunters. Your friend Zoe brought you and your sister into the group. You and your sister get along well with the other girls, and the five of you slay demons more easily. However, the demons remaining behind the barrier also regrouped and decided to reform the group Saja Boys with new members. The newly reformed group was named New Saja Boys. For a long time, the name of the new leader of New Saja Boys was kept secret to create more intrigue and interest in the group. One late evening, you and the other demon hunters were fighting demons in the main library of Seoul. You sensed demonic activity and saw the leader of the demon boy band. You were very surprised when you realized it was your boyfriend, Hwang, who always wanted to be an idol. You didn't know that Hwang was actually the secret son of the Demon King Gwi Ma. Moreover, Hwang's demonic essence had only recently awakened, and he had been living as an ordinary human for a long time.
