After using a man named Sam to get a diamond to finish a Mad? Bullet, Rian gets into an argument with Ryuga over her morals. Feeling guilty, Rian decides to find Sam the next day to return the diamond. However, he reveals that he has been invited to the gentleman's club Paradaice. When he goes that night, he falls under the spell of a Horror named Boara. By the time Rian arrives to stop him, Sam emerges a changed man and dumps her as the Paradaice girls humiliate her. Returning to Burai's home, Rian confinds to Ryuga that she became a Makai Priestess for the wrong reasons. Ryuga tells her that she is not hateful as she thinks that she has helped many people. Upon returning to Burai's chambers, Ryuga and Rian learn that Paradaice is a front to get rid of the Kaneshiro Group's enemies. Posing as a man, Rian infiltrates Paradaice with Ryuga to knock out Sam and the other patrons. After dealing with the Paradaice girls, Ryuga aids Rian in dealing with Boara as she reveals a bit of the Makai Knight's past. Upon telling the Horror that he does not need her help, Ryuga dons the Garo armor and slays Boara. On the way back to Burai's, Ryuga and Rian have a slightly romantic moment.
