You can now improve your relationship with Bravaelle (guard at the frontdoor of the deeper club). When you first meet them you have to play with the belly and then you can enter and continue the story. As soon as your in the "open world"you can visit the club at night, talk with her and play with her belly again a few nights and than she will take you to her place and... well you can go and find out ;)
Hope this helps
