Can someone explain to me how you unlock costumes? I want to get a different costume for Hanbei but I'm not getting one. while the other two characters in my team (that I don't use much -- Kunoichi and Taigong) got a third costume.
Someone explain what I should do?
I read that it has something to do with Proficiency, but Hanbei's proficiency is at S. I mostly use him.
