Top 5 in order:1.
Gekikara - Definitely my favorite out of all the characters in Majisuka, she's not only insane, she's also a scary fighter, but when I saw her side in MG 2, I liked the fact that she also has this soft side of hers and that she's willing to keep her promises, I never expected a fierce crazy yankee to have this soft side. I find it adorable when Gekikara reverts to Amakuchi, she's like an innocent child.
My oshi is Rena and I have to say, Rena's acting is seriously good, its a real bonus that she's acting Gekikara, it makes me like Geki all the more with Rena as the one portraying her. I also love Geki's laugh, no matter how creepy it sounds, also her famous line, 'Ne, Okotteru?'
2.
Black - Although I didn't get to see her much in MG 2, except in ep 10 and ep 12, I still love Black a lot, especially from MG 1, although I find her reading out some paragraphs and saying them while fighting as something weird, I like her as a fighter, she's very swift and strong, a bit disappointed that Atsuko's friends beat her, but hey, one against many is too much.
I also like how cool Black looks and when she smiles its like gazing at an angel...
3.
Nezumi - I like smart and cunning schemers like Nezumi. I also like how much she denies Center's friendship and that she doesn't seek human companionship, but after a few episodes, she gets soft and learns to accept it a little, or so I would like to think. I really like how Nezumi steers up some problems, even though they fail due to some intervening people and happenings.
4.
Team Hormone - I like them wholly, their the comic relief in MG and I can't get enough of them, they seriously make things good.
5.
Otabe - Though I didn't get to see much of her or what her real purpose or use in MG 2 is aside from taking Atsuko's place as president and keeping things at bay, or so I'd like to say, I like her, she's definitely calm, even at pressuring moments and she's also a good fighter, also her accent makes me love her so much, I like her Kyoto-ben.
Truthfully enough, I kind of ship her with Atsuko, next to TakaMina in MG for certain reasons.
