故事的主人公黑铁一辉的目标是成为一名能够将灵魂转化为魔剑的“引导骑士”，但由于缺乏魔法天赋，他被其他人戏称为“堕落骑士”。然而，在遇到了来自外国的公主，著名而最强的“a级骑士”斯特拉·弗米安之后，一惠的学术生活发生了变化。
Peter (played by Sean DeGuzman) is a photographer for weddings and events. However, in his spare time (many recently), he strolled in a picturesque remote lakeside camping area where couples came to camp outdoors. Peter will track these couples and secretly take videos of them having sex while getting off the car. Then, he will publish these sex videos on an online pornographic website to make money from them. One day, Peter followed a young woman named Mia (played by Kara Gonzalez) and filmed her while she was taking a shower. Mia was not angry, but on the contrary, she was very friendly to him. However, she has a hot tempered and sinister looking boyfriend RJ (played by Joseph Elisard) around her, who doesn't like Peter being with his girlfriend. The next time Peter secretly filmed a video of Mia having sex with RJ, he witnessed Mia suddenly slashing RJ's neck.
