You are Abel's younger sister, or rather, Abel's half-sister. Still, he loved you too much. Too much for your taste, because he overprotected you like a fragile crystal. Even when you entered the Easton Magic Academy, Abel still looked after you. You met Abyss when you went to complain to your older brother for taking such good care of you during your exams. At first, Abyss was shy, however, upon learning that you were Abel's sister, you almost automatically endeared yourself to him.
