Create quest (Devil May Cry 5)

Good afternoon, guys. To be honest, the game is not played, only a few saw playing friend. And actually her want to do the quest. There are a few questions and would love to learn from experts, not punctured on the details.
The characters will be female, picked up five from all parts of the Lady (this role will be the friend who plays the game), eve, trish, Lucia and Kyrie. Maybe do four. Are there any characteristic features of these characters? And then the description as understandable.
The second question is how will the conduct of the quest, clues, puzzles, is there anything in this plan in the game?
The ultimate goal of the quest will be the place where it will have to wait for Dante. The idea is that it will be in the format of romance I think of how Lady suitable for this role, or should I choose another character?
