Harp still had doubts that this man was a demon, but when he phased right through solid matter, it became obvious he was. Or at least, something to that caliber. One thing was perfectly certain: this man was not a human. At least, Harp couldn't imagine him being one, after he demonstrated his particular ability to phase.

Slowly, Harp would take breaths. If this man was in fact, a demon, he didn't want to aggrivate him. A creature of sin... would not hesitate to extinguish the light he radiated as an angel. The choir took note that there were no other customers I the store at this particular moment. The air, now that he noticed, smelled faintly like hairspray and cheap chemicals. A human would describe it as 'smellin' like a sex joint'. 

Taking more notice to the fact Darri seemed to respect and even fear Bel a little, Harp wondered what exactly the demon he had entranced was capable of. He had proven stronger than an elite angel, but not much was known about the demons. It was very possible Bel could be one of the higher-ups in the demon power pyramid. There was also the chance that there was no pyramid, just chaos. Actually, that seemed pretty likely. 

As Darri slid a box of what Harp presumed to be hair dye to Bel, the cupid grunted. It was probably just regular old hair dye at a rediculous price... Wait, did bel even pay? If not, then it was a win-win situation. When Bel asked him to stay there while he applied his hair dye, Harp gave him a blank stare. Unlike some angels, that could phase, or burst into light, or made spears out of nothing, Harp's power was emotions. And he needed to prick someone with an arrow for that to even work. In other words, he was pretty much defenseless should the demon try something. 

Nevertheless, the pink-eyed angel grinned. "Sure. But don't keep me waiting, okay?" With that he turned his attention to Darri, carefully backing away, showing he did not want a scuffle. Than again, what kind of fools made deals with demons? His eyes sparkled as he thought about it. Oh, right, the ones who got their souls eaten. Well, that was.... not nice to know... at all...
