Criminal Girls: Invite Only

First, learn all skills in the first tier (Maintenance). After learning the first skill in the second tier (Edgeplay), the girl should make a request. Complete the request and reduce the cost of MP for their skills or CM to motive them in the future. Active requests can be checked by checking the Status of the girl in the menu. If there is an active request, it will say so over the portrait of the girl. Press for details. It should tell you what floor of which dungeon you need to visit to complete that request. Open the map to see the whole floor. Your objective(s) should appear as a heart mark on the map. Complete the same process on each tier and you should have their final request after learning the first skill of the fifth tier (Aftercare).
