Rias Gremory from High School DxD (Pole Dance Version) (NSFW)
I like mindless harem well enough, but I dislike worthless male leads many tend to have or, Generic-kun as I name them all and also loathe the tsundere archtype.
She does occasionally show a vulnerable side, particularly when around her family, and she remonstrates Issei whenever another girl makes a move on him.
Maybe FREEing will do some bunny figure versions of Akeno and Asia; Rias is getting one and it seems like they like making their bunny girls in full sets.
