Helluva Dad

Loona had been Blitzo's adopted daughter for about nine years and since then she had never once called him "Dad" until after doing a mission with him in the human world. Doing so raises all kinds of weird feelings for Loona, as she tries to figure out why she called him such. However, she finds herself dealing with an old bed partner of hers who will not take "no" for an answer. When he goes to far in his efforts to get her, Loona can only hope Blitzo comes to help her in time.
