Hina is lower because people don't know her or have voted for girls whose names have been repeated or they don't like Loli God.
Sleeping Princess in Demon Castle is just all about cute things done by Princess Syalis Loli, 1-4 episode, She's always funny, she's always cute, she keeps repeating it, and it's boring now. (I'm thinking of dropping it because it's getting too boring) At first, I was thinking of replacing her with Hina but after a recent episode, Hina got even better IMO.
There are still some girls who are also good like Swindler from Akudama Drive (For some reasons I was thinking she is doing a job of Sakura), Miyuki from Irregular at magical Highschool: Victor Arc, Mion from Higurushi: When they Cry, Shimizu Kiyoko from Haikyuu!!
As for Nobara, I agree with Fandy. But still I like her [New Chapter Disappointed me Wtf Why did they do that to her?]
