Four at once, that was a bit too much, even for Arad.
Sena had always been lustful around him, taking any chance she got to try and seduce him. She once even tried to turn into a Void Drakaina but failed to get him.
Selica was much like her mistress, or in a more exact term, what Sena wanted, Selica wanted as well. The overprotective, rampaging, explosive woman knew what she wanted, and that was for Sena to be happy. Arad could sense a faint affection from her, but he couldn't look deeper into her intentions. All he could do was guess that Selica's affection was merely shadowing Sena.
Sara, on the other hand, was a bit special but expected. The shy, innocent, and reserved demoness often showed great power and ruthless power, which allowed her to control the criminal underworld. But in the end, she was still Abel's sister. Arad long since suspected that she hid a lustful mind beneath the veil of her innocent smile, and he was right.
