I own the first DVD as I didn't want to wait for them to come out in america. Sadly it doesn't work to well. So I just play the version I had downloaded before ordering it. The series was allright, but the OVA is so much better, so was the manga. I got mad when all the stores I went to only sold volumes 1-7 of the manga's and not 8 and 9. Hopefully tommorow I can get the last 25% of the 2nd episode downloaded.
