Mei really Isn't respected as a char, but fap material.
Konan is known for being hard core by a great amount, but still lands second to no other.
Kushina, whom is the only female char I know to have such respect and awesome fans with about like 20 panels XD
Flawless personality, skills backing her up, great choices.
IMO Kishi did well with her. I guess he didn't have the time to screw her character is all.
