I absolutely love Kyo kara Maoh! I have all of season 1 and only part of season 2 (stupid Geneon)
This series made me laugh so hard so many times! Towards the second half it does get more deep and serious but still funny. I watch all of season 1 and 2 through subs and I want to see the OAV and season 3 eventually. Hopefully another company picks up the licensing in North America but I wont hold my breath.
