Discrimination.

The gang is all tired of being discriminated against despite paying their dues and changing for the better. Wolf decides he wants to do something good so people trust him. However, when he rescues a young girl, it turns out this "girl" isn't a girl at all, but rather a middle aged woman named Hinata Hyuga, a con artist. Along with her husband Big Tuna, they plan on taking over the world! Can our favourite gang stop them? Or are we all doomed?
