Saero is a nephilim (demon-angel hybrid) living in the Abyssal Plains. He is the bodyguard of Diana, whom he is fiercly protective of and deeply in love with.
Saero’s defining trait is his loyalty, to his cause and above all to Diana, who he knew and loved since they were children. He is quick to jump into action should she be threatened at all, and would give his own life for hers should the need ever arise. He is normally quite stern, however around Diana he can be more relaxed, even playful or bashful.
