True to her title as the Angel of Mercy, she is excellent at indulging others and laughs off even the most vulgar acts. In fact, she enjoys the stimulation herself. While she provides comfort and helps her candidate, Guest, with their training, her 'Love Power' once ran low. When Guest kept acting like a spoiled child demanding more stimulation, Sariel spread her wings with her remaining strength. A stray feather caused her to sneeze, triggering her Mystic Eyes to go out of control and blow the house away. On a crowded train, even while being groped, she enjoys it, calling it a "Fabulous stimulation." Later, when the train shakes violently and she buries her chest into the person sitting in front of her, she tells them they can stay like that. Gabriel eventually stops her with a 'Pahu-Pahu' (smothering), saying anything more is out of bounds, but she enjoys that too. In her personal story, she was working to catch a thief at a clothing store. After catching the culprit, she listened to his circumstances, forgave him, and committed the absurdity of gifting him clothes. Seeing her get fooled by a story that was clearly a lie, she would have been completely swindled if Lucifer and Leviathan hadn't intervened. Later, while heading to a site where human experiments were being conducted, she encountered a man who volunteered for the experiments to become stronger and impress the woman he loved. She succeeded in making him repent through gentle comfort. As the man repented and acted like a spoiled child toward Sariel, Lucifer remarked that Sariel seemed closer to a Demon Lord than an angel. As a side note, she and Guest started as a stunning angel who suddenly appeared and her candidate master, but living together led them to fall deeply for each other. They eventually entered an intimate relationship, and now, whenever Guest desires, spending passionate and sticky time together under the guise of "indulging a spoiled child" has become a daily occurrence.
