Kaichou wa Maid-sama!, Beelzebub Recommendations
Well, the story may differ from each other but from what I have noticed is that the main character in Maid-sama, Misaki has some similarities with the supporting character in Beelzebub, Kunieda Aoi.
First of all they look somewhat similar -> face
Secondly, they both hate men and protects the girls from the boys in school.
Also, they both got feared by the most boys, except for the main guy character! Well, you know what I'm talking about right, the boy giving her some attention and finally she falls for him.
