Regan, despite her initial hesitance, found herself being the mentor of a young boy named Rex. Along with her Blade Eva, Regan goes with Rex for a very suspicious job. Things go very wrong, and she once again gets to meet the Aegis: Malos. This time, she swears to protect Rex, who had become like a little brother to her. Only thanks to Malos did Rex come back.
