I hope Jurina is only a minor one episode character b/c there were so many more interesting characters. Hope Nachu isn't as prominent either b/c she got annoying. Part of me hopes it's a prequel series showing what happened before Majisuka 1 but that's probably not likely so Yuko and Takamina will be stuck to having flashback scenes.
As long as Gekikara, Kabuki Sisters, Team Hormone and Rappapa are back, I'll definitely check it out. Hopefully Yabakune doesn't come back (Amina and Yukarin were the only good thing about them).
Some new rivals would be nice as well. Maybe Yokoyama, Yuka and Chikarina perhaps?
