This illustration gives us a rare look at Rika's casual, everyday clothes. She wears this outfit in the final scenes of
Phantasy Star IV, but it is not shown in detail there. The top is pink with a white collar, while the pants and shoes are black. We also get a another rare view - Rika's back. Her adventuring outfit includes a short cape, which typically covers her back. The second sketch here gives a peak under the cape. This would have been used by the game artists, so that they would know what is under that cape.
