You just go in every couple of hours, beat up as many trainers as possible, then repeat until the maid at the entrance tells you your rank has increased. When your rank increases you encounter new trainers and when you reach the Marchion rank, you encounter Furisode girls that uses Audino. Now, if you haven't played Gen 5, Audino gives a huge load of exp when defeated. Marchioness girls use two Lv. 35 Audino but Duchess girls use three Lv. 45 Audino. Using the o-power for exp gives incredible amounts of it and with exp. share, you can level up an entire team very quickly.
