Amyuu and the Black Torch artist are my favorite that are currently serialized. Ikeda Akihisa would be my overall favorite, wish he would come back with a new series already.

I think Sagiri is the best as well. She's a stereotypical tsundere but it's a breath of fresh air when she blames the ones at fault when Kogarashi gets into generic ecchi situations. Her cousin on the other hand is the worst:mono
