Same here, immediately 5* Westfield, if you want to progress in fight club, get Celene (Healer) asap, she gives a passive rage buff. If you have any awakening items, use them to awaken Captain first. Try to unlock Audrey as well; if not, level up Sienna and awaken her. Their 5th skills are very similar and effective.
Dumble and crocus if you want to.progress in stages
