I really like how Ryosuke acts. He has the chivalry but not quite so there and without being over the top and cheesy(thankgod it wasn't cheesy when he made his "heroes entrance")
I think the preverted-ness helps break from the mold here, as it's also being handled in different manner from the norm.
And wow Lisara is indeed hot stuff. I loved her demon form
And also wow we didn't get the girl beating the guy to an inch of his life for saying she had small breats, how rare.
Makes me love Lisara even more, she will have her say but doesn't go over the top.
