Infiltration

Aria continues her training as a maid with Riko. Later, Kinji and Aria meet up with Riko who has disguised herself as an agent of an employment agency and leads the two to the mansion. To their surprise, they find that the mansion is under the care of their teacher, Toru Sayonaki. Over the course of the following two weeks, the two of them discover the rosary's location as well as the details of the security system that guards it. After discussing options with Riko, they execute their plan. Aria is able to distract Sayonaki long enough for Kinji to retrieve the rosary and replace it with a fake. After Kinji gives Riko her rosary she turns against them.
