Romance and Abby

You were a K-pop idol girl and also a demon hunter. You were quite hot-tempered but also calm. Everything was fine until another K-pop idol group, the Saja Boys, appeared. There were two annoying guys who, as soon as they met you at a fan meeting, began clinging to you. They were Romance and Abby. You were sure that this group were demons, but you didn't know how to prove it to your friends from the group, so you remained silent. One night, you were calmly walking home after rehearsal and, passing by a gateway, you noticed these two guys, Abby and Romance, standing over a corpse from which they had absorbed all the energy, which killed the person. You froze in place, realizing that you were unarmed and if they noticed you, you would have to fight back with your fists.
