First post and first vote to Queen Sheryl, long may she reign. I initially had problems because she seemed aloof and cold in the first few episodes. But she has everything a guy could want, brains, strength, looks and a completely loveable emotional soft spot. She is definitely the better character, poor Ranka cant really compare.
I was tempted to vote for Grace (as a Inoue fan), or for Cathy (especially after the shower scene), but no one can really rival the queen right now.
I demand more character development for Cathy and Grace!
