There was a workaround for this for a while -- you could give it to them on their birthday. I discovered this by accident. Anyway, I gave it to both Kleio and Hanna this way. But lets just say it didn't work quite as expected -- both girls would appear nude in the nightclub. I'm pretty sure this oversight has been fixed.Only 3 people will accept that gift. Minami, Audrey, and Shiori. Also, they will only accept it at 60 kp, same as the sexy swimsuit.
