Selene always has a way to turn serious, dull moments into fun. One can even say she is the heart of the Chaos Dragon Harem.
While she was extremely shameless, her emotional intelligence is very high. She always made her sisters laugh, so when the situation turned a bit dull now, she made her move, and the result was now plain as day.
She lightened the mood for Dia.
During the Primordial Era, when she learned what had happened to Artemis, she became so angry that until the last second before she died, all she knew was hatred.
This followed her through the many lives she had lived. Because she was Kent's heart demon, she followed him throughout the 13 lives.
In all those lives, there was always a reason that led her to hate Kent. Not even once did she have the chance to hear Kent's side of the story. She always hated him, regardless of the kind of person she was.
